Research Focus
Dr. Emily Johnson's research lab at Johns Hopkins University focuses on understanding late-onset epilepsy, particularly how epigenetic factors and chronic health conditions contribute to cognitive decline in older adults. The lab explores the relationship between environmental exposure, genetic markers, and cognitive performance to aid dementia prevention strategies. This work is especially relevant for the over 250,000 older adults in the U.S. suffering from this condition.
