Brain stimulation comes in many different forms, but they are all centered on the same idea: sending tiny zaps to specific parts of the brain to alter its activity.
“Depression and anxiety are the top two indications for people,” Wexler said. “But other reasons people used it for were for enhancement, so to improve focus, to improve memory, things like that.”
The science behind why electrically stimulating the brain appears to aid memory and thinking abilities is still in the early stages, Wexner noted., that found that delivering small electric zaps to the brain appeared to boost memory in a group of older adults for at least one month. The study included 150 people ages 65 to 88 who did not have a diagnosed neurological disorder. Patients were asked to wear a cap embedded with electrodes for 20 minutes on four consecutive days.
In January, he purchased a tDCS device from medical equipment supplier Caputron for about $450, with the hope that it would enhance his meditation practice, as well as“I am not looking to fix anything I perceive as broken; I am looking for improvement in my mind,” Doughan said. Wexler said she doesn’t expect brain stimulation to achieve mainstream success until studies conclusively show that it provides real benefits.
“The promise of being able to noninvasively put on a cap for 20 minutes a day and change or enhance your cognitive function is something that gets people excited,” he said.Annals of Neurology
