Brain implants that deliver electric pulses can ease depression in people who aren't responding to psychiatric drugs, a new study says.
Half of a small group of people who received brain implants experienced significant improvement in their depression symptoms, researchers reported Tuesday in the journal Nature Communications.
Further, more than one-third wound up virtually depression-free following the treatment, which is called deep brain stimulation.
"Deep brain stimulation shows real promise at tackling treatment-resistant depression, which can have a huge impact on people's lives," senior researcher Dr. Valerie Voon, a professor of neuropsychiatry and neuromodulation at the University of Cambridge in the U.K., said in a news release.
