Goodbye coffee, hello brain stimulation? People are zapping their brains at home to clear brain fog

In 2021, Craig Gibbons was diagnosed with Lyme disease. His doctor prescribed him antibiotics, but the medication failed to eliminate one of his most debilitating symptoms: a lasting brain fog that made it difficult for him to focus or recall information.

So he went with a different approach: at-home brain stimulation.

Over the past few years, Gibbons had been experimenting with transcranial direct current stimulation, or tDCS, which delivers weak electrical currents to the brain through electrodes attached to the head.


Anna Wexler, an assistant professor of medical ethics and health policy at the University of Pennsylvania, studies why and how people use brain stimulation at home. She’s found that people are using the devices to treat mental health disorders or to improve mental performance.

“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.”

At-home brain stimulation began in earnest in the early 2010s, Wexler said, despite pushback from clinicians and scientists, who were concerned about safety.
