Delirium

Delirium is an acute and reversible condition that often occurs as a result of an underlying medical condition, substance intoxication or withdrawal, or medication side effects.

Electroconvulsive Therapy

Electroconvulsive therapy (ECT) is a procedure in which electric currents are passed through the brain, deliberately triggering a brief seizure. Electroconvulsive therapy seems to cause changes in brain chemistry that can immediately reverse symptoms of certain mental illnesses. It often works when other treatments are unsuccessful.
