Abstract:
OBJECTIVE:There is some evidence that repetitive transcranial magnetic stimulation (rTMS) is an effective method of treating patients suffering from obsessive-compulsive disorder (OCD). Here, we tested the hypothesis that rTMS has a positive impact both on symptom severity and cognitive performance in such patients. Specifically, short-term verbal processing speed and flexibility were assessed. METHOD:Ten patients suffering from refractory OCD and treated with standard medication were randomly assigned either to a treatment-first or to a sham-first condition. At baseline and after 2 and 4 weeks, symptom severity (experts' ratings) and cognitive performance (auditory perception, visual perception, short-term memory, and processing speed) were assessed. After 2 weeks, the treatment condition switched to the sham condition, and the sham condition switched to the treatment condition. RESULTS:Under treatment but not under sham conditions, symptom severity 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.
