Background: Advancing age increases the risk of developing dementia. Recent studies have clarified characteristic cognitive changes in very old patients with dementia. Although non‐cognitive symptoms are frequent in dementia, relatively little attention has been paid to the nature of behavioral and psychological symptoms of dementia (BPSD). Methods: A retrospective review of a database was performed to compare 27 very old patients with Alzheimer's disease (AD) (onset age ≥ 85) with 162 less old patients (onset age < 85). Cognitive decline, ability to carry out activities of daily living (ADL), and overall severity were rated. BPSD were evaluated using a 16‐item questionnaire to the compare frequency of each symptom between old and very old groups. Results: Cognitive decline was equivocal in both old and very old groups. In contrast, very old patients were more impaired in ADL, and BPSD were more frequent in very old patients. Delusions, irritability, and delusional misidentification syndrome were frequent in both groups, but were more prominent in very old patients. Behavioral abnormalities such as excitement, delirium, reversed diurnal rhythm, and wandering were not prominent in old patients, but were frequent in very old patients. Conclusions: Very old AD patients presented more frequent BPSD than old AD patients. Troublesome behavioral abnormalities particularly prominent in the older patients might represent a heavy burden for caregivers.
