Memory complaints and memory impairment in older individuals

Area of Science:

• Gerontology
• Cognitive Psychology
• Neurology

Background:

• Subjective memory complaints are common in older adults.
• The relationship between these complaints and objective cognitive function requires further investigation.

Purpose of the Study:

• To determine if subjective memory complaints correlate with cognitive test performance.
• To assess the utility of simple memory questions as indicators of memory impairment.

Main Methods:

• Cross-sectional study of 2537 community-dwelling individuals aged 65-85 in Amsterdam.
• Subjective memory complaints assessed via four questions on daily functioning.
• Cognitive function evaluated using subscales of the CAMCOG (Cognitive Assessment of Mild Cognitive Impairment).

Main Results:

• Individuals reporting memory complaints performed worse on memory and related cognitive tests.
• This association remained significant after adjusting for age, sex, and premorbid verbal intelligence.
• Complaint status and cognitive performance were independently influenced by age, sex, and intelligence.

Conclusions:

• Simple questions about memory are reliable indicators of objective memory performance in healthy older adults.
• Subjective memory complaints may serve as a valuable early marker for cognitive decline.
• Further follow-up is warranted for individuals reporting memory concerns.
