Official title
INSIDE: Intervenção da Suplementação Nutricional na Melhoria do Declínio Cognitivo no Idoso.
Overview
This study investigates the effect of nutritional supplementation on cognitive performance in older adults over a 90-day period using a double-blind randomized controlled design. The study includes 50 participants, aged 65 or older, randomly assigned to either a supplement group or a placebo group. Participants will be randomly assigned to either the experimental or control group. Assessments will be conducted pre- and post-intervention to determine the effect of the supplementation on cognitive performance. Key outcomes include cognitive status measured by MoCA, adherence to supplementation, and potential side effects. The findings will provide insights into the potential role of nutritional interventions in mitigating age-related cognitive decline.
Interventions
- Dietary supplement Nutritional Supplement
Participants in this arm will receive a daily dose of a nutritional supplement for 90 consecutive days. The supplement is administered orally and aims to improve cognitive performance in older adults with signs of cognitive decline. Participants will also complete cognitive assessments before and after the intervention. - Other Placebo
Participants in this arm will receive a daily dose of an inert placebo that matches the supplement in appearance, taken orally for 90 consecutive days. The placebo is used as a control to compare the effects of the nutritional supplement on cognitive performance. Participants will undergo the same cognitive assessments as the experimental group.
Primary outcome measures
- Cognitive Performance [Time frame: baseline and 90 days]
Secondary outcome measures (5)
- Adherence to supplementation protocol [Time frame: Daily, from Day 1 to Day 90]
- Occurrence of adverse effects [Time frame: Continuous, from baseline to Day 90]
- Self-reported use of other supplements [Time frame: Baseline and 90 days]
- Self-perceived quality of life [Time frame: baseline and 90 days]
- Depressive symptoms [Time frame: Baseline and Day 90]
