A theoretical model that provides a foundation for understanding function and dysfunction in cognition and perception is needed as a prerequisite for the development of effective assessment and treatment tools to be used with the brain-injured adult. Such a model and clear definitions are absent in the occupational therapy literature on adult brain function and dysfunction.

This paper represents a cognitive rehabilitation model adapted for occupational therapy from the fields of neuropsychology and cognitive psychology. Differentiation of terms, an overview of the model’s theory, and evaluation principles are discussed. Cognitive rehabilitation is presented from an information processing perspective. Three other treatment approaches identified in the literature are discussed and compared with cognitive rehabilitation.
