What this trial studies

This study aims to evaluate the effectiveness of a sensory stimulation device that evokes 40-Hz gamma oscillations on cognitive function and sensory processing in patients with Alzheimer's Disease. Participants will undergo assessments of cognitive function and cortical network activity using electroencephalography (EEG) and event-related potentials (ERP) before and after an 8-week treatment period. The study will explore both immediate and long-term effects of the therapy, as well as the relationship between neurophysiological changes and cognitive improvements.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 60 and older with a confirmed diagnosis of Alzheimer's Disease who can provide informed consent.

Not a fit: Patients with severe dementia or other significant medical conditions that impair cognitive abilities may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could enhance cognitive function and sensory processing in Alzheimer's Disease patients.

How similar studies have performed: While this approach is innovative, similar studies exploring gamma oscillation therapies have shown promising results in cognitive enhancement.
