Insight Into a Shocking Therapy for Depression
Since the 1930s, doctors have been jolting the brains of depressed patients with electricity to relieve their symptoms. The treatment, known as electroconvulsive therapy (ECT), works, but it can cause memory loss and confusion and lead to difficulty forming new memories. Today, physicians generally limit it to patients who are severely ill, including those at risk for suicide. Now, a brain-imaging study highlights the part of the brain most affected, perhaps pointing to safer, less-invasive ways to achieve the same results.
