Working memory helps us hold information for a short time so one can think and make decisions. It keeps thoughts on track. As one gets older, working memory gets weaker. In people with dementia, it gets much worse, making it harder to talk with others, follow directions, or remember things like shopping lists.
This may happen because brain waves that support working memory fall out of sync. Researchers can see these brain waves using a test called EEG. In this study, the investigators will try to get these brain waves back in sync using a safe, non-invasive form of brain stimulation called transcranial magnetic stimulation (TMS), and will time it to each person's brain waves to make it more effective. The goal is to improve working memory in people with dementia. If successful, dementia patients may be able to be more independent taking pressure off their families.
