Daniel W. Fisher, MD PhD

My clinical and research interests center around behavioral and psychological symptoms that present in neurodegenerative diseases, especially dementias. Though dementia is well-known to affect one’s memory and cognition, over 90% of people with dementia develop new neuropsychiatric symptoms – including apathy, dysphoria. anxiety, aggression, agitation, disinhibition, hallucinations, and delusions. Despite the ubiquity of these symptoms, very little is known about how they develop in dementia. My research interests are in understanding more about the molecular and cellular mechanisms of neuropsychiatric symptoms in dementia beyond the well-studied changes associated with cognitive deficits.

Along with my research mentor Martin Darvas PhD (Department of Laboratory Medicine and Pathology), we employ numerous approaches to better understand these neuropsychiatric symptoms, including techniques involving transcriptomic analyses of human and mouse post-mortem tissue, development and implementation of biomarkers derived from human and animal model fluids (plasma, serum, cerebrospinal fluid), virally-mediated gene manipulations, animal modeling of cognitive and neuropsychiatric phenotypes, and basic cellular and molecular biology techniques.
