Objectives:
(1) To determine if subjective memory loss (SML) is associated with Mini-Mental State Examination (MMSE) scores, (2) to determine if this association persists after adjustment for other factors, and (3) to determine the sensitivity and specificity of SML for dementia.
Population:
1751 seniors sampled from a population registry.
Measures:
Age, sex, education, SML, the MMSE, and the Center for Epidemiologic Studies-Depression (CES-D) scale. Dementia was diagnosed by clinical examination.
Analysis:
Linear regression models were constructed. The sensitivity and specificity of SML were determined with a diagnosis of dementia being the gold standard.
Results:
SML was correlated with MMSE scores, even after adjusting for age, sex, education, and depressive symptoms. The sensitivity of SML was 0.58 (95% confidence interval [CI]: 0.45, 0.71), and the specificity was 0.76 (95% CI: 0.74, 0.78) for dementia.
Conclusions:
SML is correlated with MMSE score. However, SML is neither sensitive nor specific for dementia.
Insights
Subjective memory loss (SML) correlates with cognitive test scores but is not a reliable indicator for diagnosing dementia in seniors. Further research is needed for accurate dementia detection.
Area of Science:
- Gerontology
- Neuroscience
- Cognitive Health
Background:
- Subjective memory loss (SML) is a common concern among older adults.
- The relationship between SML and objective cognitive decline requires further elucidation.
- Early detection of dementia is crucial for timely intervention.
Purpose of the Study:
- To investigate the association between SML and Mini-Mental State Examination (MMSE) scores.
- To assess if this association remains significant after accounting for confounding factors.
- To evaluate the diagnostic accuracy of SML for dementia.
Main Methods:
- A population-based sample of 1751 seniors was analyzed.
- Data collected included age, sex, education, SML, MMSE, and depressive symptoms (CES-D).
- Dementia diagnosis was established via clinical examination; linear regression and diagnostic accuracy analyses were performed.
Main Results:
- SML showed a significant correlation with MMSE scores, persisting after adjustments for age, sex, education, and depression.
- The sensitivity of SML for dementia was 0.58 (95% CI: 0.45, 0.71).
- The specificity of SML for dementia was 0.76 (95% CI: 0.74, 0.78).
Conclusions:
- Subjective memory loss is associated with objective cognitive function as measured by the MMSE.
- However, SML alone is not sufficiently sensitive or specific for diagnosing dementia.
- Clinical judgment remains essential for accurate dementia diagnosis.
