What this trial studies

This clinical trial aims to evaluate the effects of a 6-month aerobic exercise program on older adults aged 65 and above who have mild cognitive impairment or early Alzheimer's disease. Participants will engage in various exercise interventions, including moderate intensity continuous training and high-intensity interval training, while undergoing cognitive assessments and MRI scans to monitor changes in brain health and fitness levels. The study seeks to identify the most effective exercise regimen for improving aerobic fitness and cognitive outcomes, as well as to explore the underlying mechanisms of exercise on memory function. Monthly follow-ups will provide additional support and health discussions for participants throughout the trial.

Who should consider this trial

Good fit: Ideal candidates are community-dwelling adults aged 65 and older with a clinical diagnosis of mild cognitive impairment or early Alzheimer's disease.

Not a fit: Patients with significant cardiac issues or those currently enrolled in other cognitive improvement interventions may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could enhance aerobic fitness and cognitive function in older adults, potentially slowing the progression of Alzheimer's disease.

How similar studies have performed: Previous studies have shown mixed results regarding the effects of aerobic exercise on cognitive function in dementia, indicating that while some approaches have been beneficial, this specific adaptive exercise methodology is relatively novel.
