What are the long term consequences of traumatic brain injury?

A: The Centers for Disease Control and Prevention estimate that, currently, at least 5.3 million Americans 
have a long-term or lifelong need for help to perform activities of daily living as a result of a traumatic brain injury. 
According to one study, approximately 40% of those hospitalized with a traumatic brain injury have had at least one unmet need for 
services one year following their injury. The most frequent unmet needs include the following:

(1) 
Improving memory and problem solving;
(2) 
Managing stress and emotional upsets; 

(3) Controlling one's temper; and
(4) 
Improving one's job skills.

Traumatic brain injury (or, "TBI") can cause a wide range of functional changes affecting thinking, sensation, language, and/or 
emotions. It can also cause epilepsy and increase the risk for conditions such as Alzheimer's disease, 
Parkinson's disease, and other brain disorders that become more prevalent with age.
