Treatments A. Electroconvulsive therapy (ECT) B. Psychotherapy C. Selective serotonin reuptake inhibitors (SSRIs) D. Tricyclic antidepressants E. Monoamine oxidase inhibitors (MAOIs) F. Lithium G. Valproic acid A. Electroconvulsive Therapy (ECT) 1. Electric current passed through nondominant cranial hemisphere resulting in a seizure which lasts around one minute. 2. Short-acting barbiturate and muscle relaxant given to prevent a total body (tonic-clonic) seizures. 3. Duration: 10-20 treatments in 2-3 weeks. 4. Side effects: confusion, anterograde amnesia. No permanent significant changes in brain function occur. 5. ECT requires a board-certified psychiatrist, anesthesiologist and consent of the patient (or in extreme cases, a family member). 6.

Selective serotonin reuptake inhibitors (SSRIs) have fewest side-effects of all AD, block reuptake of serotonin, include Prozac, Paxil, Zoloft, Effexor. 2.

Neurological effects: fatigue and lethargy, tremor, muscle weakness; severe neurological signs: coma and death. e. Other side-effects: frequent urination, thirst, nausea, abdominal discomfort, hypothyroidism. f. Requires frequent monitoring of Li levels, thyroid and kidney function. 5. Valproic adid (Depakote) divalproex a. Proven effective in treating Bipolar Disorder. b. Formerly an anticonvulsant, antiepileptic. c. Side-effects less than Li, some abdominal discomfort, mild tremor, liver function needs to be monitored.
