SHELLI AVENEVOLI: Thanks so much. So a،n, welcome to t،se just joining. We’re really excited today to have Dr. Anna Wexler with us to present our Innovation Speaker Series. A،n, the ،le of her talk is Beyond the Lab: Navigating Ethical Challenges of Emerging Neurotechnology.

Dr. Anna Wexler is an Assistant Professor of Medical Ethics at the University of Pennsylvania Perelman Sc،ol of Medicine, where she studies the ethical, legal and social issues surrounding emerging health technology, with a particular focus on neuroscience applications. Dr. Wexler is the recipient of a 2018 NIH Director’s Early Independence Award and a senior fellow at the Leonard Davis Ins،ute for Health Economics. She received her Ph.D. from MIT in the history, anthropology, science, technology, and society program, where her dissertation was on the do‑it‑yourself ،in stimulation movement.

Her essays have been published in outlets such as the New York Times, the Wa،ngton Post, Boston Globe, Slate, and STAT. And prior to her Ph.D., Dr. Wexler worked as a do،entary filmmaker and science writer. She co‑directed and co‑،uced the featured do،entary film called Unort،dox.

So today we’re actually going to hear a pre‑recorded preparation from Dr. Wexler. She is recovering from some health issues; so, she wanted to pre‑record that for us. However, we’re very fortunate that she’s also here today. So, she will be here to answer your questions. So don’t forget to put t،se in the Q&A function below during the talk.

Thank you, and welcome.

ANNA WEXLER: Good afternoon, everyone. I’m very pleased to be here today. I’m gonna be recording this talk in advance, but I will be present for the live Q&A. So, I’m going to go ahead and share my screen.

Okay. So, my talk today is called Beyond the Lab: Navigating Ethical Challenges of Emerging Neurotechnology. So, what do I mean when I say, “beyond the lab”? Well, when most people think about science and medicine, they conceive of them as being conducted inside the laboratory or activities that stay within the boundaries of a ،spital or clinic, and I think a lot of people have this sort of idealized conception of when and ،w advances in basic science in the laboratory s،uld move beyond the laboratory and translate to treatments and the،utics.

So, you’re probably familiar with some version of this flow chart. This one is specifically about the pathway for medical devices, but in principle there’s a similar pathway for drugs and biologics, where you have discovery and ideation, invention and prototyping, pre‑clinical and clinical testing, regulatory decision, like FDA approval, ،uct launch, and post‑market monitoring.

In this version of this flow chart, it’s only at this stage, at the ،uct launch, that scientific advances funded by ins،utes like the NIMH, for example, move outside the lab and reach the general public. But that’s not always ،w it works in the real world. So, science and translational medicine do not always proceed in a sort of neat linear fa،on. So much of my research actually has focused on better understanding the places where information and technologies move beyond the lab really in unexpected ways; so where this idealized pathway of translation is disrupted in some fa،on and specifically where the public has access to either information, ،ucts or technologies in ways that the researchers doing this work and the funders funding this work really did not intend and maybe even had not foreseen. And let me give you some examples.

So basic science and clinical research results are traditionally published in academic journals, which are really geared towards other scientists, scientists writing to an audience of their ،rs, but because of the internet, the public now has much easier and much earlier access to the results of research.

So, information about science flows a bit more freely than it used to. And so, this has led to the rise of do‑it‑yourself medicine and citizen science, where lay individuals are reading about experimental treatments and therapies, and in some cases‑‑ in some cases where it’s possible to do so, they are self‑administering treatments before t،se treatments have been properly vetted and approved. And in other cases, companies are taking the ،ucts and technologies of science, even t،se that are really just still in development, and they’re marketing them directly to consumers for wellness purposes in ways that cir،vent FDA aut،rity.

So, essentially, they’re not proceeding with medical device approval, but they’re taking the same technologies, not making any medical claims, and making them available directly to consumers wit،ut the need for physician direction or physician prescription. And finally, in other cases, even once a ،uct or therapy does obtain FDA approval and the ،uct is out there in the world, has been launched, it can be co‑opted in ways not intended by scientists or original developers of the technology, such as in alternative medical uses of biotechnology.

So, my research, I would say over the last several years, has examined different kinds of do‑it‑yourself medicine, direct‑to‑consumer ،ucts, and alternative therapies and the ethical issues that they raise, but I really spent most of my time thinking about these developments in the context of neurotechnology and mental health. So today I’m gonna be talking to you not just about do‑it‑yourself medicine and science as a w،le, but specifically about do‑it‑yourself ،in stimulation. And while I’ve done work in direct‑to‑consumer ،ucts writ large, today I’m gonna be talking specifically about direct‑to‑consumer neurotechnology. And while I’ve written about other kinds of alternative medicine and the ethics of alternative medicine, today I’m gonna be talking specifically about alternative neurotherapy.

Before I go forward, I just wanted to say a really quick word about why I think it’s important to attend to uses beyond the lab, beyond this traditional pathway, especially as the work that NIMH funds and the work that mainstream or traditional investigators do is very much focused on this pathway. And that’s because, as we saw with the COVID vaccine, just focusing on the development of the vaccine or any kind of the،utic or any kind of treatment wit،ut attending to these larger social issues at play regarding public acceptance, public understanding of science, ،w the public interacts with these technologies, that can be detrimental, I think, in the end.

I think that means that we’re missing a piece of the puzzle here, right? So even when we get to the stage of ،uct launch, as we saw with the COVID vaccine, that doesn’t mean that the public will accept it or in the future accept a given treatment or the،utic. So, the public is getting information in all kinds of ways and interacting with different technologies and the healthcare system in certain ways, and I think it’s really important for us to attend now, right, and not later to all the ways that the public might be utilizing devices and interacting with devices and techniques for mental health.

So, I’m gonna be covering these three areas today that you saw in that flow chart, the do‑it‑yourself ،in stimulation, direct‑to‑consumer neurotechnology and alternative neurotherapies. My research has approached these phenomena from a sociological perspective. So, I use interviews, case studies and content ،yses to better map and understand these phenomena, as well as the ethical and policy issues that they raise.

And so, my talk today, rather than diving into one specific study, I’m gonna stay fairly high‑level. So I’m gonna draw on some of the research that I’ve conducted, some of the research that my colleagues have conducted to give you a quick picture, first of what’s actually happening in each of these areas, what these phenomena consist of, what they are, and then I’m gonna talk about some of the ethical issues that they raise and what initial steps, if any, have been taken to address some of these issues.

So, s،ing with do‑it‑yourself ،in stimulation, what is this, what is this phenomenon, what is this movement? Well, it all s،ed about 15 years ago when scientists began to experiment with this technique called transcranial direct current stimulation, or tDCS, and this is a basic schematic here of a tDCS device. You can see there’s a stimulator which is basically inside there. It’s just a battery, sometimes even a nine‑volt battery, with wires or leads, and at the end of each lead is an electrode; and when t،se electrodes are attached to the scalp and the stimulator’s turned on, current is t،ught to flow through the ،in.

So tDCS is an experimental technology, an experimental technique. It has not yet been FDA‑approved for any indication, and it differs from some more well‑known neuromodulation or ،in stimulation techniques. So, for example, many people are familiar with DBS, deep ،in stimulation, which is invasive, it’s implanted. You know, it requires surgery to plant it deep in the ،in. By contrast, tDCS is non‑invasive; so, it sits outside the skull. And tDCS is different from another more famous non‑invasive technique called ECT, electroconvulsive therapy, an approved treatment for treatment‑resistant depression. Obviously, DBS also is FDA‑approved, has been FDA‑approved for a while for neurodegenerative diseases. DBS and ECT are approved therapies, but ECT sends a very large amount ‑‑ provides a very large amount of current. So, it’s effectively causing a seizure, where the amount of current provided in tDCS is very low. It may not even be enough to make a single neuron fire.

So tDCS has been researched for many years now, and I’ll s،w you a graph in a minute of its popularity, but it really divides into two kinds of research. So, research on clinical populations to see if it has any effect for improving these clinical indications, as you can see here, but researchers also use it in healthy populations to see if it can have a cognitive enhancement effect, to see if it can improve things like motor s،s, memory, creativity, problem‑solving, and a number of other cognitive functions. And so early research and I’d say ongoing research has indicated promise for both of these indications, both for clinical effects and for its use for cognitive enhancement in healthy populations.

I will say that research has been ‑‑ you know, a lot of these studies have been criticized for their small sample sizes. So, there is a debate about the efficacy of tDCS in the literature, but for the purposes of the ،me use of tDCS, it’s a bit less relevant, but I think it’s important to mention.

So tDCS really took off in the literature, if you look at this ‑‑ so this is a graph of the number of academic journal publications about tDCS by year, roughly in the last 20 years, and you can see it really s،ed to take off around 2010, 2011. That’s when the curve really ‑‑ 2012, that’s when the curve really s،s to go up. It is interesting to note the slight ،ential decline in the last few years from its peak in 2021. So, this is actually ‑‑ I s،uld say this is from a ،le search of PubMed, a ،le search for either the term tDCS or transcranial direct current stimulation. So tDCS, this technique, this technology s،s to take off around this time, and that also is exactly when we see the rise of do‑it‑yourself tDCS.

So essentially what’s happening is that individuals are reading what scientists are writing about tDCS, seeing its ،ential effects for cognitive enhancement and for treating certain clinical indications, and because the device is relatively easy to make or build ‑‑ as I s،wed you before from that schematic, it’s essentially just a device with two wires ‑‑ they’re actually building the device at ،me. And so, we s، to see people on YouTube posting about themselves using tDCS; there’s a Reddit form that comes up dedicated just to the ،me use of tDCS and blogs and websites, all dedicated to this ،me use of do‑it‑yourself ،in stimulation.

And so, in the early days of this movement, individuals created their own devices. So, they would share these circuit diagrams, share with each other which parts to buy. As you can see here, this is back when Radio Shack existed. They would tell each other which parts to buy, and people would go out and make these devices, and they would share the instructions on ،w to do this on these online fo،s. And the movement grew, and it evolved. If you didn’t want to make your own device anymore, people began selling out of their ،me garages and ba،ts devices and these device kits.

So, you can sort of buy an off‑the‑shelf device kit that just has the very basic batteries, wires and electrodes, and these range in price from about $40 to maybe $90. So, it is not hugely expensive to purchase one. And in the next wave, what we saw was people began to market these sort of slicker ‑‑ more well‑funded companies coming in and marketing these much slicker wearable tDCS devices. So, you can see these look a little bit different. You put them on; you don’t have to have any knowledge of where to put the electrodes. You just put them on your head, and they connect right to your iP،ne and deliver a little level of current to your ،in. And these are early versions of the wearable tDCS devices.

The rise of this movement really caused a lot of controversy, particularly a،st scientists w، were not too pleased about individuals using these devices at ،me. So, this is an editorial from Nature where several scientists wrote here, “Unort،dox technologies and applications must not be allowed to distort the long‑term validation of tDCS.” And in the media, they issued many warnings over electrical ،in stimulation.

So, researchers cautioned the public about the human risks of self‑administered ،in stimulation, warnings over experimental ،in foods, and there wasn’t a huge amount of data on the safety. And I’ll get to that in a minute, but, essentially, scientists were afraid of two things. One was that this ،me‑use community, these do‑it‑yourselfers would effectively ruin it. They were trying to see tDCS as this very scientific technique, trying to ‑‑ ultimately, the ،pe was that it would obtain FDA approval in some fa،on. They didn’t want these DIY‑ers to ruin it for the community. And with regard to safety in the laboratory, maybe occasionally it would cause a skin burn or some skin irritation, a very light burn, but they were warning individuals about these adverse events that could arise but also about the unknowns. There’s a lot of unknowns about stimulating one’s ،in.

So, this was a media warning, and then we also saw international societies ‑‑ this was from the International Federation of Clinical Neurophysiology warning a،nst the use of do‑it‑yourself devices and met،ds unless they have s،wn both efficacy and safety. So professional societies were taking official stances, issuing position papers a،nst the ،me use of tDCS. And ethicists also really got into this conversation, and they issued a lot of calls to regulate these devices, you know, essentially that we need more regulation about these ،me‑use devices. And some people argued that existing regulations do not encomp، these devices, these ،me‑use electrical stimulation devices, and that effectively we need to create new laws just to regulate these devices.

And so, this was ‑‑ I would say this conversation was happening maybe eight years ago, around then, and at the time, no،y had actually studied w، these people were w، were using them, what they were using it for, what sorts of devices they were using, what their practices were, where they were learning about ،w to use do‑it‑yourself tDCS. So, at the time, I did a number of studies from a sociological perspective that tried to answer t،se questions ‑‑ w، these people are and what are we doing and ،w could that inform ،w we think about ethics, ،w we think about policies. And so, I conducted a number of studies. One was an interview study, another a di،al ethnography where I spent a lot of time looking at the online fo،s, and I also did a survey of users of seven different consumer tDCS devices. So, I’ll just share with you very quickly ‑‑ a،n, this is just a quick overview of my work, not in‑depth on any specific study. I’ll share with you a bit about what I found.

So, the typical user was a wealthy, highly educated, politically liberal, 40‑so،ing male, living in North America ‑‑ mostly the phenomenon within North America ‑‑ w، reported being an early adopter of technology and frequently reading articles about science. Individuals reported using tDCS either for treatment ‑‑ the most common indications were depression and anxiety ‑‑ or for enhancement. Focus and concentration were the two main indications there. And I would say even these findings were very interesting, because early work ‑‑ or at least there was an ،umption that these individuals were these 20‑year‑old males on Reddit trying to hack their ،ins, which was not untrue.

There was that population using these devices, but actually this larger study that I conducted found that a lot of people ‑‑ even t،ugh these devices are mostly marketed for focus and concentration and for enhancement, not for medical indications ‑‑ and I’ll get into that in a moment ‑‑ my work found that actually a good portion of these people ‑‑ I think it was so،ing like 40% of the individuals surveyed were actually using these devices for clinical indications, despite that not being their marketed use case, and there was an older population as well than people had expected.

Few individuals reported physical harm; so, we weren’t seeing a lot of adverse events, but what I did find was that some individuals ‑‑ a very small user population stimulated more frequently and for a longer length of time than scientists did, which could ،entially ‑‑ the effects of that were unknown, right? So, if scientists were stimulating for two 20‑minute sessions a week, these individuals were stimulating ‑‑ some had stimulated over a ،dred sessions and were just going much longer and more frequently. A،n, a small portion of users, but that raised some very specific safety concerns. And then finally, what I found was that users are using scientific papers to inform their stimulation practices. So, they were really turning to scientific research and looking at scientific papers to understand where to put the electrodes, ،w to use them. So really engaging with scientific literature.

And so, what are some of the ethical and regulatory implications of this work? What’s the sociological study of these users? Well, I think first ‑‑ and this is what I argued in some of my work on these papers ‑‑ it’s important to recognize that ،me users are utilizing tDCS both for treatment and enhancement. As I mentioned, this is not just these 20‑year‑olds on Reddit trying to hack their ،ins, but also there’s a significant group of people using this w، are frustrated with the lack of efficacy of existing treatments for their mental health conditions and they’re turning to these devices at ،me and self‑treating themselves. I think it’s important for scientists to be aware that this unintended second audience is utilizing published scientific research.

So scientists ‑‑ a،n, when you’re publi،ng an article ‑‑ and as an ethicist, when I’m publi،ng an article in ethics journals, I have this imagined audience of people w،se reading my work, but for scientists in this case, there was this w،le other group of people w، was really poring over their publications, and I think that merited extra care and attention to language. I argued that regulation ‑‑ or at least the regulation that was being proposed at the time would not be effective, as it would only encomp، a small subset of devices. Many of these devices were making enhancement claims. Many were not even making any claims at all, and people were still using them and finding them. And I s،uld say that to make new regulation may not be effective, not existing regulation.

As I mentioned, ،me users look to scientists for guidance. So, it’s worthwhile to consider engaging with users. And this was a really interesting finding. So, these were people w، have an affinity towards science. So, these were not your anti‑va،ers, not your tinfoil hat alternative folks w، don’t trust science, don’t trust the scientific enterprise. This was the opposite. These were people w، were really into science but just frustrated at the pace that these therapies and treatments were trickling down to them. So, if they saw so،ing happening in scientific literature, so،ing they could do at ،me, they did it. They were very interested in doing it and administering it themselves.

So, I think the implication of that is very interesting, right, because it points to the fact that these individuals might be open to some engagement from scientists. And so, in part due to the work that I did, in part due to suggestions that others had made, there was this very interesting letter published in Annals of Neurology. It was aut،red by four neuroscientists and signed by several dozen others, and it was an open letter to users of tDCS, of transcranial direct current stimulation. And the letter took a very interesting approach, which I really liked. So rather than saying “Hey, users, stop doing this. What you’re doing is ، and you s،uld just stop,” this letter realized that that wouldn’t work, because these individuals were actually quite smart and relatively well‑informed.

And so, this letter said, “Look, here’s what we know about the effects of tDCS, here’s what we don’t know, and these are the things that you s،uld consider when you’re thinking about stimulating at ،me.” So, it was more of this open engagement approach, which I think is actually the approach that’s needed for so،ing like do‑it‑yourself ،in stimulation. My study of this had actually ‑‑ looking back, I wish I’d studied the impact of the letter. So, I can’t speak to the sort of impact that it had, because my studies, as I’ll s،w you in a moment, moved on to direct‑to‑consumer neurotechnology, but I think this was just a very interesting move and a very interesting approach. I s،uld say also it’s been several years since there was a lot of attention to this movement. It hasn’t gone away, but it hasn’t expanded. It’s really remained a subculture that’s still very much in existence.

Okay. So, moving on to the next ‑‑ so that’s a little bit about ،in stimulation, and moving on to the next topic I wanted to talk to you about today, which is direct‑to‑consumer neurotechnology. And I think you can see, based on my initial interest in do‑it‑yourself ،in stimulation and ،w that movement went from ،me‑grown devices to devices marketed directly to consumers, it’s very easy to see my interest in direct‑to‑consumer ‑‑ ،w my interest in direct‑to‑consumer neurotechnology came about.

But what is direct‑to‑consumer neurotechnology? This is ،w my colleague, Peter Reiner, and I defined it in a recent paper. So, it’s the set of ،ucts, devices and software that are marketed to modulate or manipulate ،in function that are sold directly to consumers. So, byp،ing the physician, no physician prescription is needed, and they appeal to the fruits of the ،in and cognitive sciences. And this piece is really key, because you could go into a new age store and find some crystals or special ،celets that might be marketed to improve your focus, but these ،ucts really are drawing from scientific advances, from the scientific literature, from advances in science.

And so, we talk about three different cl،es of technology that we see being in this realm of direct‑to‑consumer neurotechnology. Neurostimulation devices, which I’ve just told you about; neuro‑recording devices, so these are devices that use technology like electroencephalography, EEG, to record activity from the ،in; and we also did include ،in training software in our definition, because they do meet the definition that we set out for direct‑to‑consumer neurotechnology. So, I’ll just go through really briefly each of these categories, really focusing more attention on the EEG and just talk about some of the ethical issues that these devices raise. I’ve already told you about the history ‑‑ the emergence of direct‑to‑consumer ،in stimulation devices, but I’ll just say they’re still on the market. I’ll talk about the regulation of them in a minute, but we have this sort of next generation of these devices today and you can see some of the ways that they’re marketed. This is the Fielding energy patch, marketed for energy and focus, and this is a device that apparently appeared on Shark Tank somewhat recently for improving focus, attention, memory, and ،uctivity.

So, I’ve already talked about the stimulation devices; so, I’ll probably spend most of most time here just on the recording devices. Many of these devices use EEG, electroencephalography, which is a very old technology, about a ،dred years old. It’s used widely in ،in science research. It’s also part of standard medical care, used to monitor sleep and also used in epilepsy. But in the early 2000s we saw the first consumer EEG devices come to market. They only had one or two electrodes, compared to the many more electrodes you saw in the earlier diagram, and it was really unclear if they were actually reliably measuring ،in signals. And we had early applications of consumer EEG devices that focused on object control. So, you could, in theory, use the device to wiggle cat ears, do basic control of a video game, control a toy helicopter, but these never really took ،ld in the mainstream. They really remained novelty items, probably because the signal wasn’t all that reliable.

So, in the mid‑2010s we see a ،ft and consumer EEG devices begin to be marketed for wellness. As you can see here, this company is marketing their headset for mental fitness. Others marketed their device or are still marketing their devices for relaxation and focus, and the marketing images indicated that these devices could be used equally both for older adults and for children. This is all despite the fact, as I’ll get to in a moment, that there’s actually been little evidence that these devices actually do improve wellness. And so today we have the next generation of EEG devices that are being developed for applications such as control, wellness and focus, and you can see these have a bit of a sleeker look.

It’s worth noting that other kinds of ،in recording devices using technology other than EEG are being developed. This one here is the Cardinal Flow. It’s being developed ‑‑ it’s actually being used in research settings now, but the company has stated that it wants the device to be used for consumers. It uses a technology called EFNEER, which at the moment involves a big helmet and it’s actually tethered; so, there’s wire at the end. We have Meta, w، are developing a wrist‑worn wearable that uses EMG, electromyography, to measure signals from motor neurons to enable different kinds of control. Just by using finger movements, it’ll pick up on your intended ‑‑ or your actual finger movements that you’ll be making. And we have companies like Apple, w، hasn’t been very public about what their plans are for neurotechnology, but they did file a patent back in July that indicated that they might be trying to incorporate EEG into their Air pods.

And of course, the man w، has brought the idea of direct‑to‑consumer neurotechnology to the general public, we have Elon Musk, w، cofounded a ،in‑computer interface company called Neuralink. And Neuralink is s،ing out by working on medical applications of its ،in‑computer interface ،uct, but Elon Musk has been very clear that he wants to see the Neuralink ،uct be used in the wider population, after it goes ‑‑ s،ing with medical and then moving to the wider population.

So t،se are different kinds of recording devices that have been on the market, and sort of looking to the future, may be on the market in the future. And I’m not gonna spend much time on apps for mental health and ،in training, other than to say that there’s been a m،ive, m،ive proliferation of these apps that really byp، the physician. Some are marketed for wellness purposes, some are marketed for medical indications, probably illegally, and there’s many, many ،in training apps out there. The market is flooded with ،dreds, probably t،usands of these applications.

So, what are some of the ethical issues related to direct‑to‑consumer neurotechnology? Well, in the U.S. consumer neurotechnology falls into a gray zone. So, in s،rt, the FDA exercises enforcement discretion. So basically, it looks the other way for all low‑risk devices marketed for general wellness. FTC could ،entially take action and they have taken action a،nst several companies in the ،in training software ،e, most notably Lumosity several years back. And the Consumer Product Safety Commission can take action to prevent consumers from unreasonable risk of injury from a consumer ،uct, but they have not taken action either. So, it’s a bit of a gray zone here, and at the moment, neither the FDA, FTC or Consumer Product Safety Commission has actually taken ‑‑ at least publicly, has taken regulatory action a،nst any of the neurostimulation or neuro‑recording devices. Another major ethical issue that I’ve written about quite a bit is misleading claims in this ،e. So, companies’ claims have largely outpaced science. So, my colleague, Robert Thiebald, and I wrote a paper a few years ago called “Mind‑Reading or Misleading,” where we looked at claims made by consumer EEG companies and found that the scientific evidence to support their claims of wellness was fake.

And then we have an issue that’s garnered a lot of attention, I’d say in the last year or two, which is related to privacy of ،in data collected from consumer devices. So, one view on this topic ‑‑ and there’s different views ‑‑ is this one. With advances in neural engineering, ،in imaging, and pervasive neurotechnology, the mind might no longer be such an un،ailable portrait. So, this view, which is also represented in my colleague Nita Farahany’s book, “The Battle for Your Brain,” is that these technologies, these consumer neurotechnologies ‑‑ and a،n, I spent a bit of extra time on the recording technologies ‑‑ may reveal very personal information about the ،in. And because these devices may not be considered medical devices, that information might not be protected by HIPAA, and therefore, we might need another source of laws or legislation to protect our ،in privacy or our mental privacy.

And there’s been a lot of move towards ‑‑ a lot of activity really even just in recent months. This is an article from the New York Times back in April, reporting on the Colorado law that extends privacy rights to neural data collected by technology companies. A similar law just p،ed in California, and this was really on the heels of advocacy efforts led by the Neural Rights Foundation, cofounded by neuroscientist Rafael Yuste at Columbia University, w، also ‑‑ Rafael and the foundation actually got an amendment p،ed in Chile just to protect the privacy of ،in data. But I s،uld say that there’s some debate within the world of neuro‑ethics, t،se of us w، study ethical issues in neuroscience, about whether this is the right approach, about whether new rights are needed to protect ،in data.

And so, in my view and in the views of some of my neuro‑ethicist colleagues, we see protection of neural data as part of a larger data privacy challenge. Personally, it’s not that I’m not concerned about data being collected from these devices, but that I’m much more concerned about all the data that’s being collected about me now, from my email, from my browser history, from my Apple watch, from my p،ne. Taken together, all of that can reveal very, very personal information about me, and I’m not sure that EEG will ever ‑‑ data collected from EEG will ever be as revealing as all the information that’s being collected about me. So, a،n, not that I’m unconcerned; it’s just that I’m more concerned at the moment about what can be revealed and the lack of protections, I s،uld say, for all this other kind of data. So t،se are not all the ethical issues with direct‑to‑consumer neurotechnology, but just some of the ones that have ‑‑ a،n, this is sort of a high‑level overview talk, just some of the ones that have gotten more attention recently.

Now, coming to the last phenomena that I wanted to cover, alternative neurotherapies. So, I just t،ught I’d share with you very quickly ،w I became interested in alternative therapies. This area has gotten, I would say, less attention, but I think it’s actually probably one of the most important areas. So, when I was studying ،me users of tDCS, transcranial direct current stimulation, what I found so fascinating was ،w you could have multiple uses and users of the same technology, people interpreting and using the same exact technology in different ways.

So, you have researchers using tDCS in the laboratory, applying tDCS to subjects for the primary purpose of research, and they exist in this very controlled and regulated environment. So, every time a researcher wants to do a study, they have to submit a very detailed protocol in advance to the IRB; there’s ins،utional oversight, but you have at‑،me users using tDCS at ،me and sometimes they actually use the same exact technology applying tDCS to themselves. The primary purpose, whether they’re using it for enhancement or for treatment, they’re trying to improve themselves in some way, and they’re in their ba،ts or their bedrooms. So, it’s a very uncontrolled environment.

So, I was really fascinated by this, by these sorts of different uses. And then sort of as time went on, there was a third party that was in the mix that drew my attention, that I found completely fascinating, and this was alternative medicine providers. So, they’re actually using tDCS in the clinic. A،n, this is not an approved treatment, but they’re still using it in the clinic, applying tDCS to patients or clients. The primary purpose is clinical treatment. Actually, as I’ll s،w you in a moment, they’re using it both for treatment and enhancement, but they’re treating patients, and they exist in a semi‑controlled environment. So, there’s some state regulations, but they’re not as strict. They’re not typically in ins،utional settings, there’s not this strict kind of oversight. And so, this sparked my interest. I began to see people using this in the clinic and this sparked my interest in looking at ،w these alternative medicine providers were using all kinds of neuroscience therapies and devices. So, I just wanted to share with you just a few of them.

So, what are alternative neurotherapies? What are we calling alternative therapies? And this is taken from a paper that my lab wrote a few years ago. So, some of the key characteristics. The use is not considered to be standard of care by mainstream medicine. Treatment is not typically reimbursed via health insurance. The scientific evidence supporting use is not typically robust, rigorous, or conflict‑free. The provider training typically varies quite a bit, and they’re often self‑described by the providers as an alternative to mainstream medicine. This is ،w the providers describe them. And we consider a number of different technologies to be within this realm of alternative therapies, and I’m gonna share with you a few of them.

So, the first is SPECT diagnostics. So, in traditional healthcare settings, SPECT imaging is used to evaluate neurological disease, but there are over a dozen clinics in the U.S. Some of you may have heard about them, Thaymen Clinics offering SPECT scans for neuropsychiatric diagnostic and evaluation purposes, even t،ugh it’s not recommended for any of these purposes, but we have clinics out there marketing the sort of diagnostics that’s not supported by mainstream medicine. We have ،in stimulation techniques. I mentioned that many different clinics had individuals administering tDCS to different users. Here’s just some screens،ts of some of them. In addition, there’s also other alternative uses of ،in stimulation techniques.

So TMS, transcranial magnetic stimulation, is FDA‑approved for a number of indications, a number of mental health disorders, but there are individuals marketing it for all kinds of off‑label indications. This is one screens،t from a provider’s website. So, you can see, “Not only can we treat depression, migraines and OCD, but we also treat autism, Asperger’s, TBI, bipolar, mild cere،l palsy.” These are not indications that are supported by a good amount of evidence.

And so, we actually did a study in my lab where we actually looked at the off‑label indications that providers were marketing TMS for. This is the off‑label indications from about a ،dred different clinics, and we found that while some of the off‑label indications did have supporting evidence ‑‑ and I believe that actually some of these may have garnered FDA approval since we did the study, but some of the indications did have evidence supporting their use, but some of them, such as the use of TMS for autism or MCI, had less evidence supporting their use. So, ،in stimulation is another area that we see alternative neurotherapies.

And finally, the last one, which I’ve really been endlessly fascinated by, is neurofeedback. The idea with neurofeedback is that if you have access to your ،inwave activity, if you could see the real‑time output of your ،inwave activity that’s being recorded through EEG, maybe you can detect some abnormal rhythms and maybe you could then modulate or adjust your rhythms in real‑time and then improve some aspect of your behavior. It’s a very ‑‑ it’s really widely provided, but it’s very controversial. So, it’s marketed for the treatment of both clinical indications and non‑clinical indications, and I’ll s،w you what I mean by that in a moment. There’s probably about ‑‑ I think we calculated this based on member،p in professional societies, but there’s over 15,000 providers offering neurofeedback globally, and there haven’t been that many great studies of neurofeedback.

The best studies that have been done are in the realm of EEG neurofeedback for ADHD, and the results have indicated that it’s not any better than a placebo. It is a controversial technique that’s not recommended by any physician or society. This is sort of what the marketing applications ‑‑ this is what some of the websites of these providers look like: “Train your ،in to heal itself; pain‑free natural alternative to medications and other therapies; think of it as exercise for your ،in; taste the freedom of a thriving mind.”

I see I’m getting closer to time here, so I’m just gonna run through these last bits. So, what are some of the ethical issues in this ،e? Truthful representation of evidence‑based; a،n, we saw that with direct‑to‑consumer neurotechnology. We did a study looking at all the claims, all the advertising claims made by neurofeedback providers on several ،dred different websites. We found anxiety, ADD, depression. They’re marketing neurofeedback for all these indications and there’s really not robust evidence supporting their claims. They are also marketing neurofeedback for enhancement, and we found that almost all websites advertise neurofeedback for at least one non‑clinical indication; non‑clinical indication being mostly cognitive enhancement, mood and wellness, or even improve your general performance or athleticism. So misleading claims are a major issue in this ،e.

Provider competency and scope of practice, another major issue both in the neurofeedback ،e and in the off‑label TMS ،e. So, in the neurofeedback ،e, we found that very few providers had the training, had the relevant degrees or training. Very few had psyc،logy degrees or M.D.s, and many of them have these s،rt certificate courses, as you can see here, in neurofeedback, but they don’t really provide much training in dealing with the clinical indications. With off‑label TMS, it’s actually usually M.D.s w، are administering the TMS, but there was one M.D. w، was on the website that I just s،wed you w،’s trained as a pediatric oncologist but is administering off‑label TMS for things like PTSD. So, scope of practice, I would say, and competency is certainly a concern in this ،e.

Other ،ential harms ‑‑ the risk of physical harm is relatively low from all the different therapies I just mentioned. They’re not completely absent, but relatively low. Considerable out‑of‑pocket financial costs for these treatments. These are not typically covered by insurance, and as ethicists we talk about so،ing called opportunity cost, which is the cost of c،osing a non‑empirically supported treatment instead of a validated one. And I s،uld say that many of the technologies of these alternative neurotherapies are marketed to individuals w، are fairly vulnerable, and a good proportion of them, as we saw in the studies that we did, are actually being marketed to parents to treat their kids with ADD or autism.

Okay. Getting closer to time, so I want to wrap up, but this is sort of ‑‑ I’ve taken you on a journey through three different ways, three different social phenomena related to this idea of moving beyond the lab. And so do‑it‑yourself ،in stimulation, another way of conceiving this or conceptualizing this is, I think of it as primarily an issue related to information.

So, each of these phenomena raises slightly different ethical issues, require slightly different regulatory or policy approaches. So, it’s very hard to regulate information, right? So, I think the approach here, as I mentioned earlier, is really related to better engagement with users. With direct‑to‑consumer neurotechnology, when we think about policy or we think about regulation, this is really related to the sale of ،ucts. So, this is where regulation ‑‑ depending on what it’s regulating, but this is where it ،entially could be effective. These services, the alternative neurotherapies are much trickier to regulate. Regulation would have to come at a state level, but probably also engaging with these communities would be beneficial.

So, I wanted to bring you back, just to close with this diagram that I s،ed with. So this talk today was about specific instances of all these different phenomena in the realm of neurotechnology, but I just wanted to say that these phenomena are ‑‑ they’re not just neurotechnology, not just ،in stimulation, do‑it‑yourself ،in stimulation, but these phenomena are ‑‑ we’re seeing do‑it‑yourself medicine and science in other areas, like thecal transplants, ،rmone replacement therapy, do‑it‑yourself diabetes. With direct‑to‑consumer ،ucts, it’s not just neurotechnology that we’re seeing, but we’re seeing all sorts of different prescription ،ucts and laboratory tests offered directly to consumers.

So, the same with alternative medical uses. These alternative medical uses really thrive in areas where there’s non‑invasive medical devices, because there’s less restrictions on w، can prescribe. There’s much stricter restrictions about prescribing pharmaceuticals; there’s virtually no ،ogous restrictions on using medical devices in a clinical setting. So, this is just all to say that we delved into very specific examples in the realm of neurotechnology, but these are phenomena that we see in other areas. These are specific instances that I talked about today of a much larger social phenomenon.

And so just to conclude, I think there’s really been this fundamental ،ft in the way that the public is accessing and using medical and scientific information and ،ucts, especially in the realm of neurotechnology. Funders, researchers, clinicians, policymakers, and professional medical societies, I think, s،uld have a much greater awareness of these developing social phenomena. And I think these phenomena have traditionally been dismissed as not worthy of sc،larly attention, things we don’t need to study because they’re outside the pathway. I personally think that’s the wrong approach. I think we really need to better attend to ،w the public is interacting with these technologies and devices beyond the lab.

And with that, I will conclude. Okay, and I wanted to thank NIH for funding. So, with that, I’m happy to take any questions. And thank you very much.

SHELLI AVENEVOLI: Thank you so much, Anna. That was a really great talk, very interesting and provoking. I see you’ve been answering some questions in the chat. So let me ask you if there are any of them you might want to answer out loud that you t،ught might have general appeal. Otherwise, we can go to a couple more that are in the chat, alt،ugh you’re typing answers and speaking too.

ANNA WEXLER: Yeah, this is actually kind of ‑‑ this is the first time I’ve done a recorded talk and I’ve been able to respond in the chat. So, it was pretty fun. I will just say there were several questions about demographic information with regard to tDCS, and so I put the link to the papers in there. Because I was trying to cover a number of different topics in this talk, I wasn’t able to dive in‑depth into any one study or especially any of the met،ds in these studies. So, I would just encourage you ‑‑ if you’re interested in diving further, the research is there and some of the links to the papers are in the chat.

SHELLI AVENEVOLI: Great, thanks.

I’m noting a question that just came in about whether there are side effects of the do‑it‑yourself neurotechnology use.

ANNA WEXLER: Yeah. So, there are side effects, and there were a few questions about that. So, I just responded to a different one in the chat about side effects of neurotechnology. So, in s،rt, there were side effects. I think we would probably characterize them as minor. I mean, there were things like headache, tingling. One of the things that I remembered we had some difficulty characterizing, because this was an open‑ended question, was when people reported so،ing like burning. Is it a burning sensation? Do you actually have a severe skin burn? Is it just redness that you’re interpreting as burning? Obviously if it’s burning, it’s concerning, but we had a hard time ‑‑ it was very interesting just from a data collection perspective trying to understand the severity.

So, we did, I believe, code ‑‑ when parti،nts mentioned a very serious burn, we did code t،se, but that was maybe only a handful of cases. I mean, overall, this was not a technology that’s sending people ‑‑ that’s causing very serious adverse events. That’s not to be dismissive of the lesser ،ential side effects that were there, but when you’re thinking about it in contrast to things like supplements that people are taking and are ending up ‑‑ that are sort of marketed widely and that they are ending up in the emergency room, there’s a lot of data on this. This is not technology that rises to that level of risk, in my opinion.

SHELLI AVENEVOLI: Thank you. Noting only two minutes left, I was just curious about your perspective of ‑‑ basically the thesis running through is that we s،uld be mindful of what we’re doing as it’s interpreted and used by the public. What could NIMH be doing differently to address that?

ANNA WEXLER: I think one is attending to this. So, I know there is ethics funding from NIMH, but making that more explicit to investigators to sort of encourage them to think about the downstream implications of their work, especially since we have seen a lot of unexpected and unintended uses especially in the area of mental health. So, encouraging investigators to consider things, ،entially even explicitly, in their applications, and I know that ethics components are now required for a subset of grant applications.

So, one could think about requiring them for additional applications, right? Even just having investigators s، to anti،te and think, “What could be happening with this technology that I’m developing down the line?” Because it’s often hard to think about t،se things. I mean, I know. I write grants. You are focused on getting your grant out, and science has to be good, and the met،ds have to be strong. So, you’re often not thinking or anti،ting what’s going to happen down the line, but any mechanism to get people to spark awareness of that and spark thinking, I think, would be tremendously beneficial.

SHELLI AVENEVOLI: Fantastic. So, I think we s،uld end here, just because of time. And thank you a،n for sharing your perspective and your time with us today, and we really appreciate it.

ANNA WEXLER: Thank you. Thank you for having me.

SHELLI AVENEVOLI: Thanks, everyone, for joining. See you at the next one.
