title: Episodic memory deficit in elderly adults with suspected delusional disorder.
abstract: This study examined memory functions in two groups of elderly adults with and without suspected delusional disorder (SDD). The samples consisted of 66 normal elderly subjects and 33 elderly subjects with symptoms, as reported by close informants, of delusional disorder. Subjects were matched with regard to age, gender and education, and there were no differences between the two groups with regard to performance of visuo-spatial and primary memory tasks. Subjects were examined concerning a variety of episodic recall and recognition tasks. The results demonstrated that subjects with SDD performed at a lower level than controls for some episodic memory tasks (i.e. recall tasks). There were no group differences in measures of episodic recognition or in the primary memory tasks. In addition, the group of subjects with SDD was, to the same extent as the control group, able to utilize cognitive support in the form of organization, cues and previous knowledge in order to enhance episodic memory. In summary, it appears that elderly adults with SDD have a mild episodic memory deficit in the absence of other cognitive deficits.
