* Tremors; * Ataxia; * Post-traumatic seizures and Epilepsy; * Development of Parkinson's Disease; * Impairment of the senses including loss of sight, hearing, or smell; * Changes in hormonal balance that can lead to problems with the pituitary gland; * Development of Diabetes; * Memory loss; * Damage to cognitive skills such as processing speed, distractibility, problems with multi-tasking and problem-solving; * Inability to process speech; and * A large assortment of emotional and behavioral changes of a dramatic kind.

The last on the list tends to be one of the most prevalent issues, and can often lead to a TBI patient being diagnosed with secondary conditions such as depression, OCD (Obsessive Compulsive Disorder), substance abuse issues, and more. These problems, it is believed, are due to damages sustained in specific regions of the patient's brain. For instance, a patient who has received temporal lobe damage is one prone to development of aggression disorders in the post-recovery period. On the other hand, it is the frontal lobe region that tends to create problems with childlike behavioral issues or a tendency for "dis-inhibition" to develop in the patient.

Subsequently, there is now a great deal of overall support available to the patient and any family or caregivers who are working to recover from the injury. Not only will someone who has sustained any sort of TBI require rehabilitative care, but the damages may have created radical shifts within their families too. A parent may now need more care and understanding than was ever anticipated, especially if they have developed subsequent cognitive or personality issues. This is the reason that entire families are on the receiving end of as much support and assistance as possible after someone sustains TBI.
