1 Promoting Adaptive Neuroplasticity in Mild Cognitive Impairment

The aging US population threatens to overwhelm our healthcare infrastructure, especially since the rate of Alzheimer's disease (AD) alone is expected to triple in the coming decades. Memory cause functional impairment, reduced quality of life, increased caregiver burnout, and eventual institutionalization. The diagnosis of mild cognitive impairment (MCI) identifies those with memory deficits but who remain relatively independent in everyday life. MCI provides a window for interventions that target memory functioning. The proposed study focuses specifically on a groundbreaking combination of mnemonic rehabilitation and non-invasive brain stimulation. The main idea is that brain stimulation can enhance functioning in the specific brain regions/networks, thereby increasing the patients' ability to benefit from different types of memory rehabilitation. This will be a randomized, double-blind study (active vs. fake brain stimulation), that provides multiple treatment session. Outcome will be examined using both laboratory-based and real-world memory testing as well as brain imaging. This first-of-its-kind study has the potential to meaningfully translate more "basic" science findings into neuroanatomically targeted and functionally meaningful treatments for our aging population.

2 Chronic Treatment of Alzheimer's Disease With Gamma Frequency Stimulation

In this trial, the safety and effect of daily exposure to light and sound stimulation on people with mild Alzheimer's Disease (AD) will be studied. COVID-19 Amendment: Due to the ongoing suspension of all in-person humans subject research across MIT in response to the COVID-19 pandemic, all enrolled participants who have not completed their 6-month visit will have their visit postponed to 9 months with a follow up at 18 months. Subjects who have completed their 6-month visit will still be instructed to continue and return at Month 12 for an evaluation. OPTIONAL: If the subject would like to come in for an evaluation between Month 9 and 18, we will invite participants to come on Month 12 to complete cognitive testing and EEG.
