What this trial studies

This study investigates the impact of coenzyme Q10 supplementation on cognitive function and metabolic parameters in patients with mild cognitive impairment and Alzheimer's disease who also have hyperglycemia, with or without pre-sarcopenia. Participants will receive either coenzyme Q10 or a placebo in a randomized, double-blind, cross-over design over a 12-week period. The study will assess changes in brain-derived neurotrophic factor (BDNF), glucose levels, and cognitive performance, alongside various health metrics. Blood samples and other health assessments will be collected to evaluate the effects of the intervention.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with mild cognitive impairment or Alzheimer's disease who also have hyperglycemia and may have pre-sarcopenia.

Not a fit: Patients with severe disabilities, cancer, or significant organ diseases, as well as those currently taking coenzyme Q10 supplements, are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve cognitive function and metabolic health in patients with mild cognitive impairment and Alzheimer's disease.

How similar studies have performed: While there is limited research specifically on coenzyme Q10 for these conditions, antioxidant supplementation has shown promise in related studies, suggesting potential for success.
