Affect About 25% of Seniors

1 Silent Stokes May Result in Memory Loss

Silent strokes, which may not cause any noticeable symptoms but cause small pockets of dead brain cells, may result in memory loss in older adults, says a new study. Researchers note that silent strokes may affect 25% of older adults. The study of 658 men and women, age 65 and older and with no history of dementia, revealed through MRIs that 174 of the participants had experienced silent strokes. Investigators found that these seniors performed worse on memory exams than those with no evidence of a silent stroke. "Given that conditions like Alzheimer's disease are defined mainly by memory problems, our results may lead to further insight into what causes symptoms and the development of new interventions for prevention," says study author Adam Brickman, Columbia U Med. Ctr.

Pacemaker for Brain

2 Deep Brain Stimulation for Mental Illness

Deep Brain Stimulation (DBS) may be useful for treating mentally ill patients who haven't responded to other therapies. DBS utilizes a pacemaker-type device that delivers small, steady electrical charges to brain circuits that control mood. Before treatment, surgeons implanted battery-powered electrodes in brains of patients. Researchers, reporting in Archives of General Psychiatry, found that after 24 weeks of treatment with DBS, 41 percent of patients had a positive response, and 18 percent were in remission. After two years of treatment, 92 percent had a positive response, and 58 percent were in remission. The study included 10 patients with major depressive disorder and seven with bipolar II disorder. DBS is already used for movement disorders like Parkinson's disease and dystonia.
