An Electric Forehead Patch Could Treat PTSD
28th January 2016
For some people who experience traumatic events like robberies, war, or abuse, the emotional effects continue for decades after the episode has ended. Sufferers of post-traumatic stress disorder (PTSD) are susceptible to anxiety, flashbacks, and nightmares, which isn’t always ameliorated by treatments like therapy and medication. Now researchers from the University of California Los Angeles have developed a non-invasive patch that stimulates the brain to treat symptoms of PTSD, according to a study published today in the journal Neuromodulation: Technology at the Neural Interface.
The patch uses a technique called trigeminal nerve stimulation (TNS). It’s hooked up to a 9-volt battery with which it generates small electrical currents that move through the forehead to parts of the trigeminal nerve, the largest nerve in the brain. The nerve is connected to many different parts of the brain, including the nucleus tractus solitarius, a structure found in the brainstem that is thought to integrate information from several disparate parts of the brain, including those in which patients with PTSD have abnormal activity. Targeting this nerve in particular makes TNS different from other neuromodulation techniques such as transcranial magnetic stimulation (TMS), used to stimulate neuron activity in the prefrontal cortex, and transcranial direct current stimulation(tDCS), which triggers brain cells to release painkilling compounds.
Great news.
