COGNITIVE REHABILITATION
Official Statement of the National
Academy of Neuropsychology (Reprinted from NAN Website:
http://nanonline.org/ )
Brain injury produces a complex constellation of medical consequences
including physical, emotional and cognitive deficits. The Centers for
Disease Control and Prevention estimates that approximately 5.3 million
Americans are living with disabilities resulting from acquired brain
injuries, with an estimated annual medical cost of $48 billion, and
approximately $20.6 billion is related to work loss and disability (Max,
Mackenzie, & Rice, 1991). The increased availability and use of safety
equipment in vehicles and advances in trauma medicine have been major
contributors to the increased number of individuals surviving traumatic
brain injuries.
Cognitive impairments in memory, reasoning, attention, judgment and
self-awareness are prominent roadblocks on the path to functional
independence and a productive lifestyle for the person with a brain injury.
In the early development of brain injury treatment programs it became
apparent that medical physical rehabilitation services alone were not
sufficient for comprehensive treatment. It became dramatically evident to
professionals, patients and their families that cognitive impairments, which
interact with personality disturbance, were among the most critical
determinants of ultimate rehabilitation outcome. Therefore, cognitive
rehabilitation became an integral component of brain injury rehabilitation.
The Brain Injury Interdisciplinary Special Interest Group (BI-ISIG) of the
American Congress of Rehabilitation Medicine provided a definition of
cognitive rehabilitation. Cognitive rehabilitation was defined as a
“systematic, functionally-oriented service of therapeutic cognitive
activities, based on an assessment and understanding of the person’s
brain-behavior deficits.” “Services are directed to achieve functional
changes by (1) reinforcing, strengthening, or reestablishing previously
learned patterns of behavior, or (2) establishing new patterns of cognitive
activity or compensatory mechanisms for impaired neurological systems”
(Harley, et al., 1992, p.63).
A
non-Federal, nonadvocate 16 member panel that included the professions of
neurology, neuropsychology, psychiatry and other medical and rehabilitation
disciplines, developed the National Institutes of Health (NIH) Consensus
Statement on Rehabilitation of Persons with Traumatic Brain Injury (TBI).
This panel recommended that...rehabilitation services should be matched
to the needs, strengths, and capacities of each person with TBI and modified
as those needs change over time; and rehabilitation of persons with TBI
should include cognitive and behavioral assessment and intervention (NIH
Consensus Statement, 1998, p. 23).
The difficulties inherent in the measurement and definition of cognitive
rehabilitation were addressed by Carney, et al. (1999) in a review of
selected research literature examining interventions and outcomes. The
authors concluded that, based on the evidence found in this review, we
recommend the application of compensatory strategies, adapted to patient
groups and to individuals, to improve the functional ability of persons with
TBI (p. 306). Additional valuable information and comments relevant to
this review included: identification of barriers in conducting scientific
investigations of cognitive rehabilitation, the need to address both
cognitive and personality disturbances via therapeutic interventions, the
heterogeneity of patient characteristics and the importance of reviewing
studies using single-subject or multiple-baseline methodologies (Cicerone,
1999; Kreutzer, 1999; Prigatano, 1999). Recently, the BI-ISIG has concluded
an extensive evidence-based review of 171 cognitive rehabilitation studies.
Domains of cognitive dysfunction examined included: attention, memory,
visuoperception, communication, and problem solving/executive functioning
(Cicerone, et al., 2000). Support was found for the effectiveness of several
forms of cognitive rehabilitation in alleviating impairments for persons
with traumatic brain injury and stroke. Overall, the available evidence for
the effectiveness of cognitive rehabilitation should enable clinicians to
advocate for the most effective and realistic treatments for individuals who
require services. (Cicerone, 1999, p. 320).
The National Academy of Neuropsychology supports such empirically and
rationally based cognitive rehabilitation techniques that have been designed
to improve the quality of life and functional outcomes for individuals with
acquired brain injuries. There remains a need for more evidenced-based work
to further define and tailor cost-effective cognitive rehabilitation
interventions (Ricker, 1998), and also for an expansion of the graduate
academic curriculum by offering training courses in neuropsychological
rehabilitation to adequately prepare clinical neuropsychologists to assess
for rehabilitation and to treat individuals with brain injuries (Uzzell,
2000). Most importantly, the last several decades have created a clinical
and empirical foundation to provide patients with effective cognitive
rehabilitation interventions to promote neurobehavioral recovery and to
improve opportunities for returning to productive lives.
