Between the on-going wars overseas and the long-term consequences of head injuries in sports making headlines, traumatic brain injury (TBI) has received plenty of attention lately. TBI occurs when the head or the body sustains a violent blow. Sometimes an object that actually penetrates the skull can also cause TBI. A mild case of TBI may temporarily disrupt the function of brain cells, but a more serious injury can result in long-term damage and can be fatal. The symptoms of both mild and severe TBI include loss of consciousness, confusion, nausea, and mood changes. It is critical to be evaluated by a doctor following a head injury even if the person feels fine after a few minutes.
P.S. TBI can increase the risk for Alzheimer’s disease, Parkinson’s disease, and other brain disorders that become more prevalent with age.
