Disabling compulsions in 11 mentally retarded adults: an open trial of clomipramine SR
Background:
Clinicians and researchers who work with mentally retarded subjects have reported on the frequent exhibition of mental disorders and behavioral problems in this population. Rituals are often among the disturbances described. We decided to treat disabling cleaning and collecting compulsions in mentally retarded adults with clomipramine 75 mg/day, sustained release (SR) preparation.
Method:
The 8-week trial included 11 subjects, mean age of 24.1 years (range, 21-27) with a mean +/- SD I.Q. of 65.0 +/- 11.0. The majority of subjects (N = 9) were occupied with washing rituals that took hours to complete. Subjects were started on a schedule of 32.5 mg of clomipramine SR once daily for 1 week, then received 75 mg SR once daily for an additional 7 weeks.
Results:
Improvement was assessed by using the National Institute of Mental Health Global Obsessive Compulsive Scale and the Global Improvement score of the Yale-Brown Obsessive Compulsive Scale. Statistically significant reduction in severity of rituals (p < .05) was found at the trial's completion.
Conclusion:
Once-daily clomipramine SR 75 mg is effective in treating adults with mental retardation and disabling rituals.
