The University of Pittsburgh department of neurology is conducting a research study on brain blood flow that will help them improve diagnostic techniques, leading to earlier detection of dementia changes in the brain evident in diseases such as Parkinson's and Alzheimer's. The study is open to healthy people between the ages of 25 and 85. Anyone with neurological or psychiatric disorders, taking psychoactive medications or with a family history of major neuropsychiatric disorders may not participate.
