High Frequency Stimulation to Improve Cognition, Mobility, and Affect in Individuals With and Without Subjective Cognitive Decline
University of Florida
Summary
The goal is to determine whether three months of at least three times / week of sensory flicker stimulation improves cognition, mobility, and affect in healthy older adults and older adults with and without Subjective Cognitive Decline (SCD). Investigators will also determine whether the intervention slows cortical thinning and declines in brain functional network segregation and changes in blood biomarkers of Alzheimer's Disease (AD).

Interventions
- BehavioralExperimental -- 16.67 Hz Visual Occlusion
This group will wear visual occlusion glasses with visible stimulation at 16.67 Hz (corresponding to flicker of 32-36 Hz)
- BehavioralControl - 1Hz Visual Occlusion
This group will wear visual occlusion glasses with visible stimulation at 1 Hz
