Cognitive Rehabilitation
Therapy programs which aid persons in the management of specific problems in perception, memory, thinking and problem solving.

The interventions are based on an assessment and understanding of the person's brain-behavior deficits and services are provided by qualified practitioners.
Coma

Contrecoup
Also known as coup-contrecoup. Bruising of brain tissue on the side opposite where the blow was struck.
CT Scan/Computerized Axial Tomography
A series of X-rays taken at different levels of the brain that allows the direct visualization of the skull and intracranial structures. A scan is often taken soon after the injury to help decide if surgery is needed. The scan may be repeated later to see how the brain is recovering.
