Memory impairment in the elderly: a three-year follow-up
Archives of Gerontology and Geriatrics
|July 1, 1985
Summary
Selective memory defects in the elderly worsen over time, particularly in sensory, retention, and recent memory. This senile brain deterioration may not indicate dementia but a localized memory system issue.
Area of Science:
- Gerontology
- Neuroscience
- Cognitive Psychology
Background:
- Selective memory defects in the elderly are a growing concern.
- Understanding the progression of these memory issues is crucial for diagnosis and care.
Purpose of the Study:
- To investigate the 3-year trend of memory performance in elderly individuals with selective memory defects.
- To differentiate between selective memory loss and broader demential syndromes.
Main Methods:
- A longitudinal study followed 9 elderly subjects diagnosed with selective memory defects.
- Memory performance was assessed over a 3-year period.
Main Results:
- Significant worsening observed in sensory visual memory, retention capacity, and recent memory.
- No other cognitive functions were found to be compromised in the study group.
Conclusions:
- The onset of selective memory defects in the elderly may represent senile brain deterioration localized to the memory system.
- These findings suggest that selective memory impairment does not always signify a demential amnestic syndrome.
