Problem: To determine if there are memory and cognitive differences between two groups of Alzheimer's Disease (AD) subjects; those with and without "behaviors from past self identities" (BPSI). BPSI are defined as dementia behaviors that reflect active use of an accurate past self identity. Examples include AD patients who insist they must go to work or find their young children. The behaviors can be disruptive yet no studies were found that explain BPSI or guide nursing interventions. Pilot work on BPSI (2001) found family caregivers reported twenty percent (20%) of mild to moderate AD patients had BPSI. Conceptual framework: Practice level framework hypothesized that BPSI subjects were different from other AD subjects due to spared autobiographical memory (AM) for their past, spared fluency (ability to search memory for examples), but impaired selective attention so that attention becomes inflexible and "stuck" in their past. Sample/Methods: This cross-sectional between group design study recruited a convenience sample of forty-four (44) mild to moderate AD subjects through the Michigan Alzheimer Disease Research Center (MADRC). At clinical sites, subjects completed a battery of measures for fluency, attention, and autobiographical memory. Subjects were 98% Caucasian, 54% male, and 76% resided at home. Sample means were age 77 years, 14 years education, and 16 on Mini Mental State Exam (MMSE) which is considered moderate dementia. Results: Twenty percent of moderate AD subjects had BPSI. Mean MMSE for BPSI subjects was 13.2. BPSI subjects scored significantly worse (p=.058) on a measure of selective attention (Trail Making Tests) and on a measure of past AM (incidents) (p=.047). No fluency differences emerged. Implications: BPSI are common behaviors among moderate AD patients. Findings suggest adjusting the conceptual model to reflect impoverished past AM. Findings also provide direction for planning nursing intervention studies. AN: MN030026
