Gamma-Music Based Intervention for Mild Alzheimer's Disease
Trial Parameters
Brief Summary
The study will test and refine a novel brain-stimulation tool using gamma-frequency lights coupled with self-selected music for a gamma-music-based intervention for participants with mild Alzheimer's Disease. Results will yield a gamma-stimulation protocol that reliably influences brain activity (Aim 1), is adaptive, motivating and rewarding to use (Aim 2), and will generate predictions as to who might benefit the most from gamma-MBI (Aim 3). By bridging the gap between neurostimulation and behavioral intervention by combining music therapy with gamma- band neurostimulation, the present project aims to find a sustainable intervention that delays the progression of AD.
Eligibility Criteria
Mild AD participants will be ages 55-90, amnestic (single or multiple domain) who perform below an education- adjusted cut-off score on the Logical Memory II subscale delayed paragraph recall of the Wechsler Memory Scale-Revised (WMS-R LM-IIa) (Wechsler 1987) (≥16 years: ≤8; 8-15 years: ≤4; 0-7 years: ≤2), have a CDR global score of 0.5 (with a memory box score of 0.5 or 1), have an MMSE score of 20-24, and have preserved instrumental activities of daily living (ADL) as determined by the Alzheimer's Disease Cooperative Study ADL Prevention Instrument (ADCS ADL-PI). All participants will be medically stable. Participants will not have significant cerebrovascular disease determined by history of stroke, and will have a Modified Hachinski Ischemic score (Rosen et al. 1980) of ≤ 4. Participants will not have significant psychiatric disorders including a Geriatric Depression Scale (long form) (Yesavage et al. 1982) of ≤10, and will not have a history of substance or alcohol abuse.
