Summary
Brain imaging changes like small infarcts and enlarged ventricles on computed tomography (CT) scans are linked to future functional dependence in older adults. These age-related CT findings predict a higher risk of losing independence over time.
Area of Science:
- Gerontology
- Neurology
- Radiology
Background:
- Aging is associated with structural brain changes.
- Understanding predictors of functional dependence is crucial for geriatric care.
Purpose of the Study:
- To determine if computed tomography (CT) findings in the aging brain predict future functional dependence.
- Investigating the association between specific age-related CT changes and the risk of losing independence.
Main Methods:
- 160 independently living residents aged 69+ underwent cranial CT scans.
- CT scans were assessed for ventricular enlargement, sulcal enlargement, white matter changes, and small infarcts.
- Logistic regression analyzed the association between CT findings and functional dependence over six years.
Main Results:
- Functional dependence developed in 19 participants.
- Small infarction (OR=9.27) and ventricular enlargement (OR=4.62) were significantly associated with functional dependence, even after adjusting for age, sex, medical conditions, and cognitive function.
Conclusions:
- Age-related changes observed on cranial CT scans are significant predictors of future functional dependence.
- Specific findings like small infarcts and ventricular enlargement on CT are key indicators of increased risk.
