We were awarded a large NIH Grant to carry out the ELUCID Study — a 7-center prospective longitudinal observational study on Late-Onset Unexplained Epilepsy (LoUE). ELUCID will help us understand the risk factors that underlie cognitive decline and dementia in individuals with LoUE and will allow us to develop tools needed to predict which individuals with LoUE are at greatest risk for developing cognitive decline and dementia.
