Cognitive Rehabilitation

Cognitive rehabilitation is designed to help brain-injured and cognitively impaired individuals regain functioning and compensate for cognitive deficiencies. It can help reduce further disability and address the negative, secondary responses to the situation, including loss of self-esteem and self-confidence, or depression.

Cognitive rehabilitation therapists at the Brain and Balance Center follow a system of activities aimed at reinforcing previously learned behavioral patterns, creating new patterns of cognitive activity, and enabling a person to adapt to their cognitive disability to improve their overall functioning.
