Research Interests:
The Poston Lab seeks to understand the biological underpinnings of non-motor symptoms in patients with Lewy Body diseases, such as Parkinson's disease and Lewy Body Dementia. While our primary focus is understanding cognition and dementia, we also study other prominent non-motor symptoms such as psychosis/hallucinations, sleep disruption, orthostatic dysregulation, and others. A major focus is on the role of co-pathologies, such as Alzheimer's and vascular co-pathologies, and the role of neuro-inflammation, in the development of Lewy Body disease associated non-motor symptoms. We collect clinical, motor, neuropsychological, biological, genetic, and imaging data on patients and healthy older adults to perform our studies.
