My clinical and research interests include normal aging, neurodegenerative disorders that cause cognitive impairment/dementia, neurogenetics, prion disorders, autoimmune/inflammatory encephalopathies, and the neurologically-based sleep disorders. Specific disorders of interest include mild cognitive impairment, Alzheimer's disease, Pick's disease, frontotemporal dementia, Lewy body dementia, corticobasal degeneration, posterior cortical atrophy, Creutzfeldt-Jakob disease, "Hashimoto's encephalopathy," nonvasculitic autoimmune meningoencephalopathies, REM sleep behavior disorder, narcolepsy, and restless legs syndrome/periodic limb movement disorder.
