Alzheimer's Disease

The University of Washington’s Memory and Brain Wellness Center/Alzheimer’s Disease Research Center serves as a site for observational studies and trials of potential treatments, prevention strategies, and new diagnostic approaches for Alzheimer’s disease and related neurodegenerative conditions, such as frontotemporal degeneration and Lewy Body dementia/Parkinson’s disease dementia, open for enrollment at UW Medicine.

It will also explore the alterations in HCN-mediated currents caused by human HCN1 channel mutations producing early childhood epileptic encephalopathy.
  • “Big data approach to assessing comparative efficacy of antiepileptic drugs in refractory epilepsy.” (NIH, Poolos, PI): This project will perform a comparative efficacy analysis of commonly used antiepileptic drug regimens using proprietary seizure diary datasets from and My Seizure Diary from the Epilepsy Foundation.
