This document addresses cognitive rehabilitation.
Cognitive rehabilitation refers to therapy programs which aid persons in the management of specific problems in perception, memory, thinking and problem solving. Skills are practiced and strategies are taught to help improve function and/or compensate for remaining deficits.

Cognitive rehabilitation is considered medically necessary in individuals with significantly impaired cognitive function after traumatic brain injury (TBI) if all of the following criteria are met:
Investigational and Not Medically Necessary:
Cognitive rehabilitation is considered investigational and not medically necessary for other etiologies of impaired cognitive function, including, but not limited to stroke, dementia, Parkinson's disease or anoxic brain injury.
While cognitive rehabilitation has been investigated in a wide variety of indications, the bulk of the literature has focused on traumatic brain injury and stroke. The evidence in the published medical literature is difficult to assess due to variability in study design, low power to detect difference or variation in treatment. Variation in treatment is related to the heterogeneous nature of the treated population; specific cognitive rehabilitative interventions are typically targeted to the specific deficit. Given these limitations, the published data provides the most support for effectiveness of cognitive rehabilitation in individuals with traumatic brain injury. For example, Powell and colleagues (2002) reported on the results of a randomized controlled trial of 112 participants with severe traumatic brain injury. This study suggested that a community-based multidisciplinary rehabilitation program delivered within an individualized contractual goal setting framework is effective in improving functional ability and independence. Significantly greater improvement was realized by individuals receiving the comprehensive program compared to those receiving a single therapist visit consisting of information only. In another randomized study of military personnel with a history of traumatic brain injury, Salazar and colleagues (2000) reported an improvement in outcomes with cognitive rehabilitation in those who were unconscious for more than one hour at the time of injury. As noted in the description, components of treatment vary according to the study and according to the individual. The duration of therapy also varies, with outpatient, community-based controlled studies reporting between 27 and 32 weeks of therapy, with a variable number of sessions per week. As with other rehabilitative interventions, goal setting with a demonstration of improvement toward the identified goal is an important aspect of determining the medical necessity of ongoing therapy.
A Cochrane Review evaluated the effectiveness of cognitive training and cognitive rehabilitation for mild to moderate Alzheimer's disease and vascular dementia. The evidence reviewed included 11 trials of cognitive training and a single trial of cognitive rehabilitation. The authors found no evidence for the efficacy of cognitive training to improve cognitive functioning, mood or activities of daily living in individuals with mild to moderate Alzheimer's disease or vascular dementia. The single trial of cognitive rehabilitation provided preliminary indications of the potential benefits of individual cognitive rehabilitation to improve activities of daily living in individuals with mild Alzheimer's disease. The authors recommend that more high-quality trials of both cognitive training and cognitive rehabilitation are needed in order to establish the efficacy of cognitive training and cognitive rehabilitation for individuals with early-stage dementia (Bahar-Fuchs, 2013).
Tarraga and colleagues (2006) carried out a single-blind, randomized study to investigate the effectiveness of an interactive multimedia internet based system (IMIS) which provided cognitive stimulation to individuals with Alzheimer's disease. Forty-six (46) mildly impaired individuals suspected of having Alzheimer's disease continued receiving cholinesterase inhibitors (ChEIs) during the 24-week study period. The participants were divided into three groups: (1) those who received 3 weekly, 20-minute sessions of IMIS in addition to 8 hours per day of an integrated psychostimulation program (IPP); (2) those who received only IPP sessions; and (3) those who received only ChEI treatment. At 12 weeks, the participants treated with both IMIS and IPP had improved outcome scores on the ADAS-Cog and MMSE, which was sustained through 24 weeks. The individuals treated with IPP alone had better outcome than those treated with ChEIs alone, but the effects were attenuated after 24 weeks. All of the participants demonstrated improved scores in all of the IMIS individual tasks, attaining higher levels of difficulty in all cases. Although the results suggest that the IMIS program provided an improvement above and beyond that seen with IPP alone, the researchers acknowledged that the efficacy of the IMIS-type program needs to be evaluated in larger, more diverse populations in order to understand factors that may modify the response as well as to establish its long-term (greater than 1 year) effects.
Barker-Collo and colleagues (2009) evaluated the effectiveness of Attention Process Training (APT) in improving attention and broader outcomes in stroke survivors 6 months after stroke. In this single-blinded clinical trial, 78 stroke survivors were randomized to receive either APT or standard rehabilitative care. The participants were evaluated in four aspects of attention: sustained; selective; divided and alternating as well as the auditory and visual aspects of attention. The study participants were randomly assigned to receive standard care plus up to 30 hours of APT or standard care alone. At 6 months the participants who had APT had an average improvement of 2.49 standard deviations higher than the standard care participants on "full-scale attention scores". The researchers acknowledged that APT appears to be a viable and effective means of improving attention deficits in stoke victims, but cautioned that further studies with larger samples and longer follow-up periods are needed to identify the characteristic of those individuals most likely to benefit from APT.
Bowen and colleagues (2013) updated a previously published systematic review that evaluated the effectiveness of cognitive rehabilitation for spatial neglect following stroke. The 2013 update was based on 23 randomized controlled trials involving a total of 628 participants. The authors concluded that the effectiveness of cognitive rehabilitation for increasing independence and reducing the disabling effects of neglect remains unproven. However, the authors found some very limited evidence that cognitive rehabilitation may have an immediate effect on performance of tests of neglect. The authors recommended that "until robust evidence is available, clinical practice should follow national clinical guidelines and clinicians are strongly encouraged to participate in high quality trials."
In another updated systematic review, the researchers evaluated cognitive rehabilitation for executive dysfunction in adults with stroke or other adult nonprogressive acquired brain damage. A total of 16 randomized controlled trials (n=660; 234 stroke, 395 traumatic brain injury, 31 other acquired brain injury) were included in pooled analyses. Six of the included studies (333 participants) compared cognitive rehabilitation with placebo or no treatment; none reported the primary outcome measure and data from 4 studies did not demonstrate a statistically significant effect of cognitive rehabilitation on secondary outcomes. Ten studies (448 subjects) compared an experimental cognitive rehabilitation method with a standard cognitive rehabilitation method. Only 2 of these studies (82 subjects) reported the primary outcome; no statistically significant effect was found. Data from 8 studies (404 participants) demonstrated no significant effect on the secondary outcomes. Three studies (134 subjects) compared cognitive rehabilitation with sensorimotor therapy. Of these studies, none reported the primary outcome, and data were only available relating to the secondary outcomes from one of the studies. The authors summarized their findings as follows:
There is insufficient high-quality evidence to reach any generalized conclusions about the effect of cognitive rehabilitation on executive function or independence in activities of daily living. Further high-quality research comparing cognitive rehabilitation with nonintervention, placebo, or sensorimotor interventions is recommended (Chung, 2013).
Sammers and colleagues (2006) examined the effect of cognitive training on cognitive performance of 26 individuals with Parkinson's disease (PD). Half of the subjects participated in a cognitive training regimen, while the other subjects received standard treatment. The results demonstrated improved performance of the group with cognitive treatment in two executive tasks after the training period, while no improvement was seen in the group receiving standard treatment. While the results of the study are encouraging and suggest that individuals with PD might benefit from a short-term cognitive executive function training program, larger, randomized controlled trials with longer follow-up periods are needed before conclusions regarding its effectiveness can be drawn. It also remains to be seen if the therapy results in improvement in the everyday life of the individuals.
In the study completed by Flavia and colleagues (2010), researchers evaluated the efficacy of a computer-based intensive training program of attention, information processing and executive functions in individuals with clinically-stable relapsing-remitting (RR) multiple sclerosis (MS) and low levels of disability. Examinations were performed on 150 individuals with RR-MS who scored less than or equal to 4 on the Expanded Disability Status Scale (EDSS). Information processing, working memory and attention were assessed using the Paced Auditory Serial Addition Test (PASAT) and executive function evaluated by the Wisconsin Card Sorting Test (WCST). Individuals with one or more clinical exacerbations in the previous year, loss of visual acuity, ongoing major psychiatric disorder, substance abuse or a Mimi Mental State Examination score of less than 24 were excluded from the study. Twenty clinically-stable subjects with RR MS were included in the study and were casually assigned by a blinded psychologist to either a study group (n=10) or a control group (n=10). Therapy continued for a period of 3 months. The researchers concluded that a computer-based intensive training program focused on attention, information processing and executive functions is effective in individuals with RR MS and low levels of disability. Larger studies with longer periods of follow-up are needed before these results can be generalized and to demonstrate that the effects of the training persist over time.
In the evidenced-based review of cognitive rehabilitation for individuals with multiple sclerosis, researchers concluded that cognitive rehabilitation for multiple sclerosis is still in its infancy stage and more methodologically rigorous research is needed to determine the effectiveness of the various cognitive rehabilitation interventions (O'Brien, 2008).
While cognitive rehabilitation has been demonstrated to be an effective treatment option for individuals who have suffered a TBI, additional research and well designed studies are needed before conclusions can be drawn regarding its benefits in individuals with multiple sclerosis, Parkinson's disease and those who have suffered a stroke.
According to the Centers for Disease Control and Prevention (CDC), "a traumatic brain injury is caused by a bump, blow or jolt to the head or a penetrating head injury that disrupts the normal function of the brain." These injuries are principally the result of motor vehicle accidents, violence, sports injuries, and falls. Individuals who have suffered a TBI often experience residual impairments affecting motor control, communication skills, social behavior and cognition. These deficits may result in a variety of alterations in the individual, including but not limited to changes in memory, language, attention and concentration, visual processing, reasoning, and problem-solving, as well as emotional and behavioral control. Psychosocial changes may include high levels of anxiety, depression and pervasive personal loss (e.g., interpersonal relationships, social supports, employment, and leisure activity). Accordingly, TBI may have a profound effect on everyday functioning and independent living. (BCBSA, 2008)
The TEC Assessment Program defines cognitive rehabilitation as:
Cognitive rehabilitation is a structured set of therapeutic activities designed to retrain an individual's ability to think, use judgment and make decisions. The focus is on improving deficits in memory, attention, perception, learning, planning, and judgment. The term, cognitive rehabilitation, is applied to a variety of intervention strategies or techniques that attempt to help patients reduce, manage or cope with cognitive deficits caused by brain injury. The desired outcome of cognitive rehabilitation is an improved quality of life or an improved ability to function in home and community life. (TEC, 2008)
Cognitive rehabilitation (CR) is distinguished from occupational therapy, which describes rehabilitation that is directed at specific environments (i.e., home or work). In contrast, CR consists of tasks designed to develop the memory, language and reasoning skills that can then be applied to those specific environments. CR may be performed by a physician, psychologist, or a speech or occupational therapist.
As with other rehabilitation services (e.g. physical, speech or occupational therapy), CR services may undergo periodic review to assess how the individual is progressing and to determine the expected length of time CR will be required. It is generally expected that a treatment plan will include, but is not limited to, documentation that the individual is an acceptable candidate for CR, expected outcomes, expected duration of therapy and evidence of progress toward stated goals as demonstrated by objective functional measurements. In general, the documentation should provide evidence that there is progress towards reasonable, measurable goals, and that CR continues to be appropriate. Examples of documentation that may result in therapy not being approved or being discontinued, include but are not necessarily limited to the following:
Cognitive rehabilitation has been proposed as a treatment approach for individuals with cognitive defects, including, but not limited to those individuals who have suffered TBI, Parkinson's disease, stroke and multiple sclerosis.
Cognitive function: The ability to selectively focus on information, obtain knowledge, and properly apply knowledge; the conscious intellectual activity of knowing, thinking, learning, judging, reasoning and remembering.
Cognitive stimulation: One of the therapeutic strategies frequently included in a cognitive rehabilitation program.
Rehabilitation: A structured set of therapeutic activities that are directed at re-entry into familial, social, educational and working environments, the reduction of dependence on assistive devices or services, and the general enrichment of quality of life.
Traumatic brain injury (TBI): Damage to the brain caused by a bump, blow or jolt to the head or a penetrating head injury that disrupts the normal function of the brain. Most instances of traumatic brain injury are the result of motor vehicle accidents, violence, sports injuries and falls.
