Background:
To date, there are no published data investigating the role of age in the clinical and neuropsychological presentation of mild cognitive impairment (MCI). The aim of the study was to evaluate whether age at the time of evaluation modulates clinical, functional or cognitive profiles in MCI subjects.
Methods:
A total of 167 outpatients with a clinical diagnosis of MCI were consecutively enrolled and entered in the study. Clinical and demographic characteristics were carefully recorded. Each patient underwent a wide neuropsychological standardized assessment.
Results:
MCI subjects were divided into 3 groups according to their age at observation time: 58 MCI patients were classified as young (≤ 69 years), 89 as old (70-79 years) and 20 as very old (≥ 80 years). The 3 groups did not differ in demographic characteristics, general cognitive functions and memory impairment. Very old MCI subjects showed a significantly greater impairment than younger MCI patients in cognitive domains involving executive functions. In particular, very old MCI patients were more frequently classified as having multiple-domain amnestic MCI.
Conclusion:
Present data highlight that the clinical presentation of MCI is affected by age: at presentation, very old MCI subjects show a worse performance than younger MCI subjects on multiple abilities, particularly on executive functions.
Insights
Age significantly impacts mild cognitive impairment (MCI) presentation. Very old individuals with MCI exhibit greater executive function decline compared to younger patients, indicating age-related differences in cognitive profiles.
Area of Science:
- Neuroscience
- Gerontology
- Cognitive Psychology
Background:
- Limited research exists on age-related variations in mild cognitive impairment (MCI) clinical and neuropsychological profiles.
- Understanding these age-related differences is crucial for accurate diagnosis and management of MCI.
Purpose of the Study:
- To investigate whether age at evaluation influences the clinical, functional, or cognitive characteristics of individuals diagnosed with MCI.
- To identify specific cognitive domains affected by age in the MCI population.
Main Methods:
- 167 outpatients with a clinical diagnosis of MCI were enrolled.
- Demographic and clinical characteristics were recorded.
- A comprehensive neuropsychological assessment was administered to all participants.
Main Results:
- MCI patients were categorized into three age groups: young (≤69), old (70-79), and very old (≥80).
- No significant differences were observed in demographics, general cognition, or memory impairment across age groups.
- Very old MCI subjects demonstrated significantly greater impairment in executive functions compared to younger MCI patients.
- A higher proportion of very old MCI patients were classified as having multiple-domain amnestic MCI.
Conclusions:
- Age demonstrably affects the clinical presentation of mild cognitive impairment.
- Very old individuals with MCI show poorer performance across multiple cognitive abilities, especially executive functions, compared to younger counterparts.
- These findings underscore the importance of considering age when assessing and characterizing MCI.
