What this trial studies

This study investigates the effects of transcranial alternating current stimulation (tACS) at a gamma frequency of 40 Hz on patients diagnosed with mild cognitive impairment (MCI) due to Alzheimer's disease. The approach involves applying tACS to the precuneus region of the brain, which has shown promise in improving episodic memory and increasing gamma power in previous studies. Participants will undergo magnetoencephalography (MEG) to monitor brain activity and network changes before, during, and after the stimulation. The goal is to replicate earlier findings and assess the potential of tACS as a non-invasive treatment for cognitive decline.

Who should consider this trial

Good fit: Ideal candidates are individuals recently diagnosed with amnestic mild cognitive impairment confirmed by multidisciplinary assessment and cerebrospinal fluid biomarkers.

Not a fit: Patients with serious neurological, psychiatric, or somatic comorbidities, or those with conditions that interfere with MEG recordings, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new non-invasive treatment option to slow or prevent the progression of cognitive impairment in Alzheimer's disease.

How similar studies have performed: Previous studies have shown promising results with similar approaches using tACS in patients with Alzheimer's disease and mild cognitive impairment.

Eligibility criteria
