Research Information
Dr. Truitt’s research focuses on cognitive and behavioral outcomes associated with neurologic disease, traumatic brain injury, and behavioral health. Her work has examined the prevalence and clinical impact of traumatic brain injury among individuals seeking treatment for opioid use disorder, as well as factors influencing cognitive and functional outcomes across diverse patient populations. More recently, her research has included investigations of functional assessment measures in older adults and individuals at risk for Alzheimer’s disease. Through clinical research and neuropsychological investigation, Dr. Truitt seeks to improve the assessment and understanding of cognitive health across the lifespan and enhance care for individuals affected by neurologic and neuropsychiatric disorders.
