About

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.

Enrollment: 50 estimated patients

Inclusion and exclusion criteria

Inclusion Criteria:

• Inclusion Criteria:

Community-dwelling adults aged 65 years or older Evidence of mild cognitive decline (score < 26 on the Montreal Cognitive Assessment - MoCA) Ability to provide written informed consent Willingness and ability to comply with study procedures and attend scheduled evaluations

• Exclusion Criteria: Diagnosis of dementia or any neurodegenerative disease (e.g., Alzheimer's, Parkinson's) Epilepsy and neurologically related conditions Severe sensory deficits (e.g., profound visual or hearing impairment) that impair cognitive assessment Current use of cognitive-enhancing medications or supplements that cannot be discontinued History of allergy or intolerance to components of the nutritional supplement Unstable chronic medical conditions (e.g., uncontrolled diabetes, heart failure, renal insufficiency) Participation in another clinical trial in the previous 3 months

50 participants in 2 patient groups, including a placebo group

Nutritional Supplement

Experimental group

Description:

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.

Treatment:

Dietary Supplement: Nutritional Supplement

Placebo

Placebo Comparator group

Description:

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.

Treatment:

Other: Placebo
