Valproic acid

Valproic acid and derivatives (divalproex sodium) have been reported as useful for aggressive behavior and for impulse control, primarily in individuals diagnosed with Alzheimer's disease. In placebo-controlled studies valproic acid displayed little or no benefit. Valproic acid and related drugs may cause liver damage and require blood tests to periodically check liver function. Many practitioners also order blood levels, which adds to the cost of drug therapy.
