This research seeks to understand and identify predictive functional relationships in neurodegenerative diseases, specifically traumatic brain injury (TBI) and Alzheimer’s disease (AD). TBI is a leading cause of death in persons under the age of 45, and AD is the leading cause of dementia and a leading cause of death in persons over the age of 65. Despite the apparent difference in relevant populations, previous research has shown links between the two as well as between each disease and age.
