Sertraline response in adults with mental retardation and autistic disorder.

Department of Psychiatry, Kansas University Medical Center, Kansas City 66160, USA.

BACKGROUND: Self-injury and aggression are common reasons for urgent psychiatric referral of persons with mental retardation and autistic spectrum disorders. Although the treatment prescribed for these problems has traditionally been neuroleptic medication, serotonin reuptake inhibitors such as sertraline may result in significant clinical improvement as well as fewer side effects. METHOD: The authors administered sertraline in an open trial to nine consecutively admitted adult mentally retarded outpatients presenting with target behaviors of self-injury and/or aggression. Most patients (N = 6) were mildly or moderately mentally retarded by DSM-III-R criteria; five had comorbid autistic disorder. Prescribed dosages ranged from 25 mg to 150 mg daily, based on observed clinical responses. Clinical Global Impressions (CGI) ratings were made at baseline and again after sertraline treatment for at least 28 days. RESULTS: Sertraline led to improvement in CGI ratings of overall clinical severity in eight of nine subjects; mean +/- SD improvement in CGI ratings was 2.44 points +/- 1.67. Discontinuation of the treatment was necessary in only one patient, after 18 weeks of sertraline treatment, because of agitation and worsening of self-picking. Side effects were otherwise minimal. CONCLUSION: These findings from a clinical sample suggest that sertraline is promising in the treatment of self-injury and aggression. Double-blind controlled studies of sertraline and other serotonin reuptake inhibitors in the treatment of self-injury and aggression in patients with mental retardation and with autistic disorder are warranted.
