Memory Disorders in Old Age

The purpose of this study is to see if stimulation of the brain can improve memory. The investigators will use a device called transcranial magnetic stimulation that can stimulate and activate a specific part of the brain that is important for memory. The study will enroll MCI subjects and subjects with subjective memory complaints who will be randomly assigned to receive active or sham brain stimulation. 'Blinded' or 'sham-controlled' means that the subject will not know whether the treatment they receive is the active treatment or the non-active stimulation. In the 'sham' condition, the stimulator will turn on but will not actually be stimulating the target brain region.

The Interventions for Brain Health Virtual Reality Study is a NIH-funded clinical research trial at the University of California San Diego (UCSD) Health under the supervision of the study principal investigator Dr. Judy Pa. The overarching goal of this trial is to use a novel virtual reality (VR) based intervention that simultaneously engages physical and cognitive activity aimed at improving brain health and cognition in older adults. The investigators will compare 3 types of interventions: physical activity, VR cognitive activity, and combined VR physical and cognitive activity over 16 weeks to evaluate physical and brain health changes.
