What are the potentiallong-term effects of a brain injury?

A: There are mild and severe forms of brain injuries with side effects that can last for just a brief period or for the rest of your life. In general, the more severe the brain injury, the higher chance you have suffered a permanent, debilitating traumatic brain injury (TBI).  Some of the long-term effects may include epilepsy or seizures, Alzheimer's disease, dementia pugilistica, post-traumatic dementia, Parkinson's Disease, and other problems with motor skills, among others. A TBI may require the assistance of a nurse or medical professional on a daily basis. A mild brain injury is less severe but could lead to reduced motor functions and memory loss.
