The therapeutic effects of valproate in psychiatric conditions are most sub
stantially recognized in bipolar disorder. However, this well-tolerated med
ication may be beneficial in the treatment of other mental illnesses. In th
is article, the authors comprehensively review studies of valproate as trea
tment for psychiatric conditions, including bipolar, depressive, anxiety, a
nd psychotic disorders; alcohol withdrawal and dependence; tardive dyskines
ia; agitation associated with dementia; and borderline personality disorder
. Valproate shows the most promising efficacy in treating mood and anxiety
disorders, with possible efficacy in the treatment of agitation and impulsi
ve aggression, and less convincing therapeutic response in treating psychos
is and alcohol withdrawal or dependence. The authors conclude with a brief
summary of its mechanism of action and therapeutic spectrum.
