Brief summary

The goal of the proposed study is to evaluate the efficacy and safety of memantine in kleptomania.

Detailed description

The proposed study will consist of 8 weeks of treatment with memantine in 10 subjects with kleptomania. The hypothesis to be tested is that memantine will be effective in reducing the urges to steal in patients with kleptomania. The proposed study will provide needed data on the treatment of a disabling disorder that currently lacks a clearly effective treatment.

Design outcomes

Primary

MeasureTime frameDescription
Yale Brown Obsessive Compulsive Scale Modified for Kleptomania (KM-YBOCS)Week 8 (last visit)Scores could range from 0-40 with 0 being the least severe and 40 being the most severe. Here the total score was used. The Yale Brown Obsessive Compulsive Scale Modified for Kleptomania (KM-YBOCS) was completed at every visit (1-5), but the final visit (visit 5) will be the only score reported. The scale was given at baseline and weeks 2, 4, 6, and 8. Only the last visit (week 8) will be reported here.

Secondary

MeasureTime frameDescription
Kleptomania Symptom Assessment Scale (K-SAS)Week 8 (last visit)Scale used to measure severity of kleptomania. Scores could range from 0-36 with 0 being the least severe and 36 being the most severe. Here the total score was used. The K-SAS was completed at every visit (1-5), but the final visit (visit 5) will be the only score reported. The scale was given at baseline and weeks 2, 4, 6, and 8. Only the last visit (week 8) will be reported here.
Clinical Global Impression Severity Scales (CGI)Week 8 (last visit)The overall impression of the clinician of the severity of the subject. Scores between 1 and 7 with 1 not being ill at all and 7 being one of the worst cases seen. CGI is given at baseline and weeks 2, 4, 6, and 8. Only the last visit (week 8) will be reported here.
