Gregory (Gregg) S. Day, M.D., is a neurologist, dementia specialist and clinical researcher. Dr. Day is focused on improving the clinical diagnoses and characterization of common and uncommon causes of dementia, including neurodegenerative and autoimmune-mediated brain diseases. His research integrates clinical and paraclinical measures such as structural and functional neuroimaging and biofluid biomarkers. Dr. Day employs these methods to determine the causes and contributing factors of dementia, improve clinical diagnosis, and optimize treatment with the goal of improving long-term patient outcomes.
Focus areas
- Dementia. Dr. Day aims to determine the causes of dementia with a special focus on rapidly progressive forms of dementia. This work includes studies designed to identify and apply protein measures in blood and cerebrospinal fluid to recognize specific causes of dementia during the life span.
- Creutzfeldt-Jakob disease. This area of research seeks to advance diagnosis and care for patients with this disea
- Treatment-responsive dementia. The goal of this research is to improve the recognition of patients with dementia that is potentially responsive to treatment early in the symptomatic course of the disease.
- Advancing treatment. Dr. Day evaluates the effectiveness of dementia medications in clinical trials.
- Autoimmune encephalitis. Dr. Day focuses on designing and leading clinical trials for patients with this condition.
