There is considerable evidence in the literature for the presence of non-verbal and praxic memory deficits in OCD. Such deficits may represent the cognitive substrate of doubt-related phenomenon such as checking. Neuropsychological tests of non-verbal memory functioning and memory for actions were administered to patients with OCD (whose predominant symptom was checking) and a group of matched healthy controls. Significant differences were found between the experimental and control groups, suggesting some memory impairment in the OCD group; however, no significant relationship was found linking neuropsychological test indices with checking. Significant relationships were found linking recognition memory problems and immediate memory for actions with general symptom severity.
