  • The study aims to identify the transition from normal aging to dementia by analyzing neuropsychological data, memory complaints, and social activities among older adults.

However, their relationship or the relationship between these findings and cognitive function has not been fully studied. We investigated the relationship between CC atrophy, WMH, and hippocampal atrophy, together with frontal executive dysfunction in both normal aging and AD.

However, this might be the result of overdiagnosis stemming from some problematic diagnosis of VaD or of the frequent use of magnetic resonance imaging to detect cerebrovascular disease in older adults.

Objectives: We investigated the prevalence of dementia and the ratios of dementing diseases.
