Persons who sustain cerebral injuries often have cognitive impairments. Occupational therapists are active in providing cognitive rehabilitation that aims to minimize the effects of cognitive deficits in their clients' lives. This paper presents a brief review of the literature in the area of cognitive rehabilitation including major characteristics of existing occupational therapy models related to the treatment of people who need cognitive rehabilitation. A model of cognitive rehabilitation is proposed that emphasizes functional components of occupational therapy in different rehabilitation settings. This model, called the Functional Model of Cognitive Rehabilitation, supports the use of activities in naturalistic settings in treatment, in order to enable those with cognitive impairments to fulfill their occupational roles.
