The document compares and contrasts three major treatments for Major Depressive Disorder: cognitive therapy, electroconvulsive therapy, and psychopharmacological therapy. Cognitive therapy aims to change negative and unrealistic thoughts through counseling and problem-solving techniques. Electroconvulsive therapy is often a last resort for severe cases, as it is an intense medical procedure that can cause memory issues. Psychopharmacological therapy uses antidepressant drugs, which the National Institute of Mental Health study found highly effective for severe depression. Each treatment targets depression differently, through changing thought patterns, stimulating the brain, or altering biological functioning.
