The use of drug treatments in patients with personality disorders rema
ins controversial. The target for treatment is symptoms that arise fro
m underlying biological vulnerabilities rather than the personality di
sorder itself. In antisocial personality disorder (ASPD), the trait sy
mptoms that may respond to drugs are impulsive and violent behaviour.
As there have been no specific placebo-controlled treatment studies of
patients with ASPD, no specific drug treatment recommendations can be
made. However, there is limited evidence based on trials of patients
with antisocial behaviours that antipsychotics, mood stabilisers and a
ntidepressants may sometimes be helpful in patients with ASPD. Well de
signed drug treatment studies are urgently needed.
