Cognitive Rehabilitation Therapy (CRT) is the process of relearning cognitive skills including attention, executive, memory, visuospatial, problem solving and communication that have been lost or altered as a result of damage to brain cells/chemistry. If skills cannot be relearned, new ones are taught to enable the person to compensate for their lost cognitive functions. The process of CRT comprises 4 components: Education about cognitive weaknesses and strengths. The focus here is on developing awareness of the problem. Process Training. This refers to the development of skills through direct retraining or practicing the underlying cognitive skills. The focus here is on resolving the problem. Strategy Training. This involves the use of environmental, internal and external strategies. The focus here is on compensating rather than resolving the problem. Functional Activities Training. This involves the application of the other three components in everyday life. The focus here is on real life improvements.
