What this trial studies

This study aims to develop non-invasive repetitive transcranial magnetic stimulation (rTMS) protocols to prevent cognitive decline in individuals with mild cognitive impairment (MCI) and those at high risk for Alzheimer's disease. A total of 60 participants aged 50-80 will undergo 30 intervention sessions, each lasting between half an hour to an hour, with MRI and cognitive assessments conducted before and after the interventions. The study will evaluate the effects of three different rTMS protocols over a period of approximately four weeks, with a focus on enhancing hippocampal plasticity and cognitive function.

Who should consider this trial

Good fit: Ideal candidates are English-speaking individuals aged 50-80 with mild cognitive impairment who can commit to daily sessions for four weeks.

Not a fit: Patients with other neurological disorders, untreated depression, or contraindications to TMS or MRI may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could help prevent or slow cognitive decline in patients with mild cognitive impairment.

How similar studies have performed: Other studies have shown promise with rTMS in enhancing cognitive function, suggesting potential for success in this approach.
