Deep brain stimulation effective in resistant depression
A new study in the American Journal of Psychiatry says deep brain stimulation is an effective treatment in depressed patients who do not respond to other forms of therapy. The study published on October 4, 2019, looked at the long-term effects on patients who had received electrical stimulation to the subcallosal cingulate area of the brain. The subcallosal cingulate area of the brain is also called Brodmann Area 25, and has been targeted by researchers as a possible focus for antidepressant stimulation.
Deep brain stimulation (DBS) is a neurosurgical procedure in which an implant is placed deep within the brain. This implant, called a neurostimulator, emits electrical signals at a selected high frequency to stimulate that particular part of the brain. DBS has been used to treat Parkinson’s disease, epilepsy, obsessive-compulsive disorder and essential tremor, four conditions for which it has gained US Food and Drug Administration (FDA) approval.
