Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 25-65 with a clinically confirmed diagnosis of Down Syndrome.

Probably not a fit

Patients with dual diagnosis of Down Syndrome and Autism or those with a history of seizures or epilepsy may not benefit from this study.

What this trial studies

This study investigates the effects of non-invasive gamma frequency stimulation using light and sound on individuals with Down Syndrome, who are at increased risk for Alzheimer's Disease. The research aims to assess the safety, feasibility, and cognitive performance of this stimulation method by recruiting 30 participants with Down Syndrome and 30 cognitively normal adult controls. Participants will undergo brain wave assessments using electroencephalogram (EEG) during the stimulation sessions. The goal is to determine if this approach can modify disease progression and improve cognitive function in this population.

Why it matters

Potential benefit: If successful, this study could lead to a novel non-invasive treatment that slows cognitive decline and improves memory in individuals with Down Syndrome.

How similar studies have gone: Initial pilot studies have shown promise in using similar gamma frequency stimulation methods in cognitively normal adults and those with mild Alzheimer's Disease.
