Abstract:
The objective of this study is to identify, in a sample of very mild Alzheimer disease (AD) patients, factors associated with disease progression. The authors followed 160 AD patients from a multicenter cohort with a Clinical Dementia Rating (CDR) of 0.5, corresponding to very mild AD but with impairment insufficient to be classified as dementia. Patients with disease progression were defined as those with CDR> or =1 at 1 year; those with no progression (stable) remained at CDR 0.5. The baseline characteristics of these 2 groups of patients were compared in search of predictors of progression. After a 1-year follow-up, 84 (52.5%) of the patients remained stable, CDR 0.5; 76 (47.5%) progressed to a CDR score > or =1. A baseline lower nutritional status assessed by the Mini Nutritional Assessment [odds ratio 0.80, 95% confidence interval (0.68-0.94), P=0.007] and a lower cognitive performance on the Alzheimer Disease Assessment Scale [odds ratio 1.22, 95% confidence interval (1.07-1.39), P=0.003] were found as predictors of progression. The results suggest that clinical assessment of nutritional status, along with cognitive data, may help detect patients at risk of progression in very early AD. Nutritional assessment should therefore form part of clinical evaluation of patients with AD at an early stage of the disease.
Insights
Poor nutrition and lower cognitive scores predict Alzheimer disease (AD) progression in patients with very mild AD. Early nutritional assessment can help identify at-risk individuals.
Area of Science:
- Neurology
- Geriatrics
- Nutritional Science
Background:
- Alzheimer disease (AD) diagnosis often occurs at later stages.
- Identifying early predictors of progression in very mild AD is crucial for timely intervention.
Purpose of the Study:
- To identify baseline factors associated with disease progression in patients with very mild Alzheimer disease (AD).
- To determine if nutritional status and cognitive performance predict progression in early-stage AD.
Main Methods:
- A multicenter cohort study followed 160 patients with very mild AD (Clinical Dementia Rating [CDR] 0.5) for 1 year.
- Progression was defined as a CDR score >=1 at 1-year follow-up.
- Baseline nutritional status (Mini Nutritional Assessment) and cognitive performance (Alzheimer Disease Assessment Scale) were compared between stable and progressed groups.
Main Results:
- 47.5% of patients progressed to CDR >=1 within 1 year.
- Lower nutritional status (OR 0.80) and lower cognitive performance (OR 1.22) at baseline were significant predictors of progression.
- These findings highlight the importance of early assessment of these factors.
Conclusions:
- Nutritional status and cognitive performance are key predictors of progression in very mild AD.
- Integrating nutritional assessment into routine clinical evaluations can aid in identifying patients at high risk for AD progression.
- Early detection facilitates timely therapeutic strategies for better patient outcomes.
