Abstract

OBJECTIVE: There is some evidence that repetitive transcranial magnet ic stimulation (rTMS) is an effective method of treating patients s uffering from obsessive-compulsive disorder (OCD). Here, we tested the h ypothesis that rTMS has a positive impact both on symptom severity and cog nitive performance in such patients. Specifically, short-term verbal pro cessing speed and flexibility were assessed.

METHOD: Ten patients suffering from refractory OCD and treat ed with standard medication were randomly assigned either to a treatment-fir st or to a sham-first condition. At baseline and after 2 and 4 week s, symptom severity (experts' ratings) and cognitive performance (auditory perception, visual perception, short-term memory, and process ing speed) were assessed. After 2 weeks, the treatment condition switched to the sham condition, and the sham condition switched to the treatment co ndition.

RESULTS: Under treatment but not under sham conditions, symptom sever ity reduced. Moreover, cognitive performance improved in parallel.

CONCLUSIONS: rTMS is a safe and efficient treatment for patients suffering from refractory OCD; symptoms and cognitive performance improved in parallel.
