Recall and recognition memory in obsessive-compulsive disorder

This study examined recall and recognition memory in 20 nonmedicated patients with obsessive-compulsive disorder (OCD) ann 20 matched control subjects. As hypothesized, OCD subjects showed abnormalities affecting delayed recall of nonverbal information but showed normal recognition. These results are interpreted as providing preliminary evidence of a nonverbal memory retrieval deficit consistent with proposed corticostriatal system dysfunction in OCD.
