What’s the buzz? The benefits and risks of ‘brain zapping’
Key Takeaways: In a growing trend, some people are using at-home devices that initiate transcranial direct current stimulation (tDCS)—also known as "brain zapping"—in order to reap a range of purported neural and psychological benefits. Patients are using these devices in hopes of improving mood, memory, creativity, and learning, and also to combat symptoms associated with COVID-19, ADHD, and Alzheimer's disease. Experts say there are risks involved in using tDCS, and as the devices are not yet approved by the FDA to treat specific conditions, they should be considered a “recreational” device as opposed to a medical device.
