Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Overture Study is a randomized, controlled, single-blind multi-center clinical trial using the GammaSense Stimulation system to study safety, tolerability, and efficacy in people with mild to moderate cognitive impairment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Overture Study (CA-0005) is a Phase I/II randomized, controlled, single-blind multi-center clinical trial using the GammaSense Stimulation device to study safety, adherence rates and efficacy in subjects with mild to moderate cognitive impairment (MMSE 14-26) who are age 55 and older.

Subjects who pass screening will be randomized (ratio 2:1 Treatment to Control). Subjects and their caregivers will be blinded to their randomization group, as will key raters at each site. The device will be used for 60 minutes daily during the 6-month therapy phase, followed by a one month safety follow-up visit.
