What this trial studies

This clinical trial aims to enhance working memory in patients with Mild Cognitive Impairment (MCI) by combining cognitive training with non-invasive brain stimulation using transcranial alternating current stimulation (tACS). The intervention targets the critical stage of MCI, which is often a precursor to dementia, by leveraging neuroplasticity to improve cognitive functions. Participants will undergo a structured program that integrates both cognitive exercises and tACS to potentially delay the progression of cognitive decline. The study is designed to assess the efficacy of this combined approach compared to traditional cognitive training alone.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 60 and older who have been diagnosed with Mild Cognitive Impairment and have completed at least six years of schooling.

Not a fit: Patients with other neurodegenerative diseases, significant psychiatric conditions, or a history of epilepsy may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could help maintain cognitive function and improve quality of life for patients with Mild Cognitive Impairment.

How similar studies have performed: Other studies have shown promising results with similar non-pharmacological interventions for cognitive enhancement in MCI, suggesting potential for success in this approach.
