(NewsNation) — A new health craze growing in popularity is apparently brain zapping while at home.
Transcranial Direct-Current Stimulation (tDCS) sends weak electrical currents to the brain through a device attached to the head. Some of the at-home devices range in price from $40 to $500.
Enthusiasts say the at-home stimulation can give a mental edge and eliminate brain fog in some cases. But, some scientists say they are not sold on the at-home options being a safe, long-term solution.
Anna Wexler, assistant professor of medical ethics and health policy at the University of Pennsylvania, speaks about possible risks or potential benefits of the devices.
