A recent Medscape article: “ECT Reduces Suicide Risk in Severe Depression: New Data”
Quote:
ECT was effective for suicide prevention in patients with severe depression with co-morbid psychosis (HR, 0.20; 95% CI, 0.08 - 0.54; P = .001) but not in patients with moderate or severe depression without psychosis.
“In psychotic cases, the effect is actually very, very large,” said Nordenskjöld.
