Current Research and Scholarly Interests
Dr. Poston's research applies multi-modal neuroimaging to study cognitive impairment and dementia in patients with Parkinson’s disease (PD), Lewy Body Dementia (LBD), and other parkinsonian disorders. Dementia is a highly prevalent and grievous consequences of PD, but it is an essentially untreatable symptom that has multiple, evasive etiologies. Dr. Poston's lab uses neuroimaging to unravel these etiologies by studying brain regions vulnerable to various co-pathologies that develop in PD patients, and then determining the associated changes in clinical progression and symptom evolution. She integrates genetic, biospecimen, and pathological data into these studies, which aid in understanding the biological underpinnings of these neuroimaging studies.
