Consequences of TBI

Common consequences of TBI may be described as being of three major types: cognitive-communicative (e.g., attention, memory, social appropriateness), physical (e.g., headaches, hearing, vision) and psychosocial/emotional deficits (e.g., anxiety, depression, irritability). Specific consequences of TBI vary from person to person depending on site, severity (mild/moderate/severe), and extent of injury to the brain. Each of these areas can impact the others. With appropriate rehabilitation and other supports, a person with TBI may be able to improve function in these areas.

Examples of common cognitive-communicative, physical, and psychosocial/emotional consequences after Mild, Moderate, and Severe TBI follow:
