The Rise of Neurotechnology: How Wearables Are Pushing Boundaries Beyond Fitness
•
Oct. 13, 2024
Wearable technology has seen tremendous growth over the past decade, with smartwatches, sleep trackers, and fitness devices becoming mainstream. However, a new frontier is emerging that promises to revolutionize the health and wellness industry: neurotechnology wearables. These are devices designed to interact with and stimulate the brain, offering non-invasive therapeutic treatments for various physical and mental health conditions.
Unlike traditional neurotech, which is often associated with invasive brain implants, wearable neurotechnology works externally—through the skin and skull—to stimulate brain activity. These devices, which apply mild electrical stimulation to the brain, aim to treat chronic health conditions such as depression, anxiety, insomnia, and even metabolic disorders like obesity and diabetes. With decades of research behind them, neurotechnology wearables are now on the cusp of a major breakthrough, and they are set to reshape the future of medtech.
The neurotechnology wearable space is still relatively small, but several companies are working on bringing this technology to the masses. One such company is Flow Neuroscience, which has developed a wearable device to treat depression through transcranial direct current stimulation (tDCS). The device delivers low electrical currents to the user's brain via pads placed on the forehead, stimulating the brain in a way that could potentially lift mood and reduce depressive symptoms.
Another UK-based startup, Neurovalens, has been working for over a decade on non-invasive brain stimulation technology aimed at treating not just psychological conditions but metabolic disorders like obesity and diabetes. As research advances and regulatory approvals are secured, these devices are expected to become widely accessible, creating a new wave of wearable medtech.
Flow Neuroscience’s device, affectionately referred to as a “little zapper” by users, is a prime example of how neurotechnology wearables are already making an impact. One user, who had experienced years of low mood and depression, reported feeling substantial improvement after using the device regularly. Unlike traditional antidepressants, which can come with a slew of side effects such as weight gain, low libido, and emotional numbness, Flow’s non-invasive tDCS offered relief without these downsides.
The user described the experience of using the device as “feeling like little ants biting at your forehead,” but found the process relaxing and calming. They reported a progression from deep depression to anger, and finally to a relaxed state they had not experienced in years. This anecdotal evidence, while not definitive, demonstrates the potential for neurotech wearables to offer new therapeutic options that do not involve pharmaceuticals.
Neurotechnology wearables work by manipulating the brain's natural electrical activity. Dr. Camilla Nord from Cambridge University explains that brain cells communicate through electrochemical signals, and changing the brain's electrical signals can alter thoughts, emotions, and behaviors. While traditional pharmaceuticals target brain chemistry to treat mental health conditions, neurostimulation works by directly altering the brain's electrical activity.
This approach presents a promising alternative to drug-based therapies, especially for conditions like depression that are resistant to medication. With fewer side effects and the potential for earlier intervention, neurotechnology wearables could provide patients with a safer, more effective way to manage chronic health conditions.
For those concerned about the safety of applying electrical currents to their brain, experts assure that the levels of stimulation used in commercial neurotech devices are minimal and fall well within safe limits. The low levels of stimulation used in devices like Flow are unlikely to pose risks when used as recommended. However, long-term effects remain less well understood, and further research is needed to fully understand the implications of sustained use.
One of the most exciting prospects of wearable neurotech is that these devices could be used earlier in the treatment process, potentially before patients are prescribed medication. This could lead to better health outcomes by addressing mental and physical health issues at an earlier stage.
Despite the promise, bringing neurotechnology wearables to market is not without its challenges. The regulatory landscape for medical devices is fragmented, with different requirements in different regions. In the U.S., for example, the Food and Drug Administration (FDA) has tightened its rules for approving brain stimulation devices following a history of less-rigorous approvals. Newer devices must now go through the FDA’s Premarket Approval (PMA) process, which requires clinical trials and evidence of both safety and efficacy.
In Europe, the regulatory process involves gaining a CE mark, a certification that demonstrates compliance with health, safety, and environmental protection standards. Flow Neuroscience, for example, has already obtained a CE mark, allowing it to sell its devices to consumers across Europe. However, for true market penetration, companies like Flow must also secure reimbursement from national healthcare systems, a process that can take years.
Beyond medical applications, neurotechnology wearables are also gaining traction in the consumer market, with products aimed at brain training and mental performance. Devices like Alphabeats and Neurable are pushing the boundaries of how consumers can use neurotech to improve focus, attention, and even mental performance.
Alphabeats, for instance, offers a brainwave-detecting headband that works in tandem with an app, providing real-time feedback on focus levels during activities such as listening to music. Similarly, Neurable’s smart headphones, developed in partnership with audio brand Master & Dynamic, track brain activity to help users optimize their mental performance at work.
While brain training apps have existed for years, incorporating EEG (electroencephalogram) technology into wearable devices offers a more precise and data-driven way to monitor and improve cognitive performance. As consumer interest in mental health and wellness continues to grow, neurotech wearables are positioned to play a significant role in this burgeoning market.
The future of neurotechnology wearables is incredibly exciting. As technology continues to improve, we can expect to see even more sophisticated devices hitting the market. These wearables will not only offer new treatment options for chronic health conditions but could also unlock new capabilities for cognitive enhancement, memory training, and mental health optimization.
While the road to mainstream adoption is still filled with challenges—particularly in the areas of regulation, reimbursement, and long-term safety—there is no doubt that neurotechnology wearables have the potential to transform healthcare. By offering non-invasive, drug-free treatments for mental and physical health conditions, these devices represent a new frontier in both medtech and wellness.
Wearable neurotechnology is a rapidly growing field with immense potential to revolutionize the way we treat chronic health conditions, particularly in the areas of mental health and metabolic disorders. With continued research, investment, and regulatory approval, neurotech wearables could offer a safer, more effective alternative to traditional drug therapies.
Whether through direct-to-consumer products or as part of a healthcare provider’s arsenal of treatment options, neurotechnology wearables are poised to become a key player in the future of health and wellness. As more startups enter the space and regulatory pathways are navigated, the wearable neurotech industry is set to redefine how we approach both preventative care and treatment.
