Abstract
Objective: To evaluate the effects of supplementation on cognitive function and nutritional status in elderly people with Alzheimer's disease from a philanthropic institution. Methods: Multiple case study, approved by the ethics and research committee of CONEP / Plataforma Brasil (N ° 2,423,431). A nutritional diagnosis was performed: weight, height, BMI, waist circumference and calf and the evaluation of cognitive function by mini mental examination; After starting the omega 3 supplementation (2 capsules being 1000mg of DHA), magnesium (1 capsule of 400mg) and vitamin B12 (1 capsule of 500μg) in the period of 90 days, reevaluated every 30 days. Eight elderly patients were divided into two groups: Control Group (N = 4, not supplemented) and Supplemented Group (N = 4). Results: Elderly patients with Alzheimer's disease were overweight and had a high CVD risk and low cognitive function in the initial period there was a significant difference in weight gain after 60 days when compared to baseline (p-value ≤ 0.05) and waist circumference. The supplemented group increased their total score of 55.8%, while control group reduced to 25.3% (p-value ≤ 0.05). Conclusion: Supplementation in the elderly with Alzheimer's caused a significant improvement in cognitive function; in the nutritional state there were significant changes in weight and waist circumference after 60 days.
