Research in my lab is aimed at understanding the structural, functional and biochemical basis of brain aging and neurodegenerative diseases associated with brain aging. We use techniques of positron emission tomography (PET), magnetic resonance imaging (MRI), functional MRI, and neuropsychology and cognitive neuroscience to study normal older people, and patients with neurodegenerative disorders of Alzheimer's disease and related dementias and Parkinson's disease. Studies are using PET imaging to detect the deposition of brain amyloid, and we are also looking at how changes in neurotransmitters are related to behavioral changes in aging. Our goals include early detection of Alzheimer-related changes with PET and MRI scanning, using imaging to track treatments in both Alzheimer's and Parkinson's disease, and understanding the fundamental mechanisms of cognitive change in the aging brain.
