The ability to use language can be progressively disrupted by neurodegenerative diseases of the brain that target circumscribed regions that normally mediate language in healthy individuals. My clinical and research interests focus on Individuals with Primary Progressive Aphasia, Frontotemporal Dementia and Alzheimer's Disease. Research projects address the neuropsychological, neuroimaging and neuropathological variables associated with these syndromes, in order to contribute to our understanding of risk and the genetic factors that determine regional brain vulnerability to these diseases and to identify biomarkers that can be used in diagnosis during the patient's lifetime. To date, there are no biomarkers that definitively predict the type of the neuropathology in these clinical syndromes in the individual patient. Additional interests in the area of brain aging and its effects on cognition lie in determining factors associated with "Superaging", the maintenance of a high level of cognitive ability into the 9th decade of life and beyond.
