title: Impaired episodic memory for events encoded during mania in patients with bipolar disorder.
abstract: To date, very few studies have focused on autobiographical memory in patients with bipolar disorder. We examined whether mood state at the time of event encoding (i.e., manic, depressed, euthymic) influences subsequent recollection in these patients. We administered the Autobiographical Interview, a method that allowed us to dissociate episodic and semantic aspects of autobiographical memory. We also compared the memory perspective from which patients recollected these events. Patients were selectively impaired in recollecting episodic details of events encoded during mania but not depression or euthymia. No significant differences emerged between patients and controls for recollection of non-episodic details, regardless of mood state. Patients with bipolar disorder were also more likely than matched controls to recall memories from an observer perspective. These preliminary findings indicate a moderating influence of mood state at the time of event encoding on the subsequent recollection of autobiographical events in patients with bipolar disorder.
