Aggression, insomnia, headaches, and even seizures. A traumatic brain injury can have life-altering consequences for individuals and their families. Today we’ll hear from Dr. Sandeep Vaishnavi, a neuropsychiatrist at Duke University Medical Center and the co-author of "The Traumatized Brain: A Family Guide to Understanding Mood, Memory, and Behavior after Brain Injury," published by John Hopkins University Press. We'll met Tom and Mary Longest, a husband and wife who struggled to adjust to their "new normal" after an accident. And we speak to Dr. Kevin Crutchfield, director of the Comprehensive Sports Concussion Program at LifeBridge Health and a neurological consultant for the Baltimore Ravens, about the potential impact of repeated brain trauma.
