Autobiographical memory and executive function in early dementia of Alzheimer type
Greene JD, Hodges JR, Baddeley AD.. Neuropsychologia, 1995-12-01
Topic: Amyloid, tau and blood-test diagnosis
We studied executive function and autobiographical memory in a cohort of 33 DAT patients [divided into minimal (MMSE 24-30) and mild (MMSE 17-23) groups] and in 30 normal controls. Autobiographical memory, as assessed by autobiographical fluency and the Autobiographical Memory Interview (AMI), was impaired in DAT patients, even those with minimal disease. There was evidence of a gentle temporal gradient on the incident but not the personal semantic component of the AMI, suggesting that the two components are dissociable.

Key findings
- Autobiographical memory, as assessed by autobiographical fluency and the Autobiographical Memory Interview (AMI), was impaired in DAT patients, even those with minimal disease.
- There was evidence of a gentle temporal gradient on the incident but not the personal semantic component of the AMI, suggesting that the two components are dissociable.
- Executive function was assessed by two separate dual performance tasks and letter fluency.
- Although there was a trend for minimal DAT patients to be impaired on executive tasks, this only reached significance for the mild group.
Why it matters
This study examined autobiographical memory and executive function in early dementia of Alzheimer type. It is a cognitive characterization study and provides no information on treating, curing or preventing Alzheimer's disease.
