What this trial studies

This study investigates the effects of high-definition transcranial direct current stimulation (HD-tDCS) combined with cognitive training on patients with early Alzheimer's disease. Participants will undergo cognitive assessments and receive either active or sham HD-tDCS over a period of 10 days. The study employs a double-blind design to ensure unbiased results, with random allocation to treatment groups. The primary outcomes will be measured using various cognitive and neuropsychological tests to assess improvements in memory and cognitive function.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with early Alzheimer's disease or related conditions, with mild cognitive impairment as indicated by specific cognitive assessment scores.

Not a fit: Patients with moderate to severe Alzheimer's disease or those with significant psychiatric or neurological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance cognitive function and quality of life for patients with early Alzheimer's disease.

How similar studies have performed: While the use of tDCS in cognitive enhancement is being explored, this specific combination with cognitive training in early Alzheimer's disease is relatively novel.
