Cognitive rehabilitation is a therapeutic approach designed to improve cognitive functioning after central nervous system insult. It includes an assembly of therapy methods that retrain or alleviate problems caused by deficits in attention, visual processing, language, memory, reasoning, problem solving and executive functions. Cognitive rehabilitation comprises tasks designed to reinforce or reestablish previously learned patterns of behavior or to establish new compensatory mechanisms for impaired neurologic systems.  The desired outcome of cognitive rehabilitation is an improved quality of life or an improved ability to function in home and community life.  Cognitive rehabilitation may be performed by a physician, psychologist, or a physical, occupational or speech therapist.


Cognitive Rehabilitation Treatment Duration

Duration and intensity of cognitive rehabilitation therapy programs vary:

  • One approach for comprehensive cognitive rehabilitation is a 16 week outpatient program consisting of 5 hours of therapy a day, 4 days per week. In this approach cognitive group treatment occurs for three 2-hour sessions each week and three 1-hour session (total of 9 hours per week).
  • Cognitive rehabilitation programs for specific deficits, such as memory training or visuo-spatial deficits which may be considered less intensive, generally have 1 or 2 sessions (30 to 60 minutes) per week for 4 to 10 weeks

For the aging population, including patients with Alzheimer disease, and for patients with cognitive deficits due to post-encephalopathy, autism spectrum disorder, seizure disorder, multiple sclerosis, brain tumor or previous treatment of cancer, evidence on cognitive rehabilitation is insufficient to permit conclusions. Larger studies with longer follow up are needed to demonstrate durable benefits of cognitive rehabilitation therapy in these patients.

2011-Evidence Based Review for Cognitive Rehabilitation

Objective: To update our clinical recommendations for cognitive rehabilitation of people with traumatic brain injury (TBI) and stroke, based on literature review from 2003 and 2008.


Conclusion: There is substantial evidence to support interventions for attention, memory, social communication skills, executive function and for comprehensive-holistic neuropsychologic rehabilitation after TBI (traumatic brain injury). Evidence supports visuospatial rehabilitation after right hemisphere stroke, and interventions for aphasia and apraxia after left hemisphere stroke.


2013 Evidence Based Review of Cognitive Rehabilitation in Medical Conditions Affecting Cognitive Function:

The American Congress of Rehabilitation Medicine has developed clinical recommendations for cognitive rehabilitation interventions for individuals with traumatic brain injury (TBI) or stroke.


Summary and Recommendations
  • Brain Neoplasms
    • Probably effective in treating attention and memory deficits in children and adolescents who undergo resection, radiation or both after diagnosis of brain neoplasm.
    • Evidence of effectiveness of these approaches in adults with brain neoplasms is equivocal, thus preventing a recommendation to be made for adults in this population.
  • Epilepsy/Seizure Disorders: practice option that cognitive rehabilitation for attention and memory deficits, with additional techniques for internalization of strategy use, may be effective for individuals with seizure related deficits in attention and memory. It is recommended that further cognitive rehabilitation research involving individuals with seizure disorders consider including strategy use as a specific component of training.
  • Anoxia/Hypoxia: There is currently insufficient evidence to recommend or contraindicate the use of cognitive rehabilitation in individuals with cognitive impairment from anoxia or hypoxia. It is recommended that foundation cognitive rehabilitation research with this population being with single-subject or small sample studies with careful subject selection (i.e. individuals screened for relatively milder deficits and indications of learning potential), using targeted interventions, and aimed at measurable functional goals.
  • Encephalitis: There is currently insufficient evidence to make recommendations for the use of cognitive rehabilitation with postencephalitis cognitive deficits.
  • Toxic Encephalopathy: There is insufficient evidence to date to support putting forward a treatment recommendation in this area.
  • Parkinson’s Disease: There is insufficient evidence to make recommendations for cognitive rehabilitation for individuals with Parkinson’s disease.
  • Huntington Disease: There is insufficient evidence to date to support putting forward a treatment recommendation in this area.  
  • Systemic Lupus Erythematosus: There is insufficient evidence to date to support a treatment recommendation in this area. It is recommended that researchers of this population focus in areas of cognitive difficulty also common to other diagnostic groups (e.g. attention and/or memory), select individuals with identifiable, yet treatment deficits, and choose intervention methods based in process training and strategy use.  


National Institute of Health and Care Excellence (NICE)

National Institute of Health and Care Excellence guidance (2013) on stroke rehabilitation recommends cognitive rehabilitation for visual neglect and memory and attention deficits that impact function. Interventions should focus on relevant functional tasks, e.g, errorless learning and elaborative techniques (mnemonics, encoding strategies) for memory impairments.


INCOG Guidelines for Cognitive Rehab

The team recommends that individuals have detailed assessments of cognition after resolution of posttraumatic amnesia. Cognitive assessment and rehabilitation should be tailored to the patient's neuropsychological profile, premorbid cognitive characteristics, and goals for life activities and participation. Clinical algorithms and audit tools to evaluate current practice are provided.


Classification of Traumatic Brain Injury

Traumatic brain injury is frequently classified using multiple scoring symptoms. These can include time of unconsciousness, changes in brain imaging, and multiple scoring systems. The Glasgow Coma Scale/Glasgow Coma Score (GCS) is frequently utilized to determine severity of brain injury. Persons with a GCS of 13-15 are classified with a mild traumatic brain injury.


Glasgow Coma Score

The GCS is scored between 3 and 15, 3 being the worst, and 15 the best. It is composed of three parameters : Best Eye Response, Best Verbal Response, Best Motor Response, as given below : Persons with a score ≥ 13 would be considered to have a mild traumatic brain injuy.

  • Best Eye Response. (4)
    1. No eye opening.
    2. Eye opening to pain.
    3. Eye opening to verbal command.
    4. Eyes open spontaneously.
  • Best Verbal Response. (5)
    1. No verbal response
    2. Incomprehensible sounds.
    3. Inappropriate words.
    4. Confused
    5. Orientated 
  • Best Motor Response. (6)
    1. No motor response.
    2. Extension to pain.
    3. Flexion to pain.
    4. Withdrawal from pain.
    5. Localising pain.
    6. Obeys Commands.

Cognitive rehabilitation may be considered medically necessary in the rehabilitation of patients with cognitive impairment following a stroke or  moderate to severe traumatic brain injury in addition to these conditions, all of the following criteria must be met:

  • The service must be ordered by the attending physician and be part of a written plan of care; and
  • The service(s) is so complex that it can be safely and effectively performed only by a qualified licensed professional such as a physician, a psychologist, physical therapist, occupational therapist and/or speech therapist; and
  • The individual is capable of actively participating in a cognitive rehabilitation program, as evidenced by mental status demonstrating responsiveness to verbal and visual stimuli and ability to follow commands and process and retain information; and
  • The individual’s mental and physical condition prior to the injury indicates there is significant potential for improvement (e.g. a complete recovery of pre-injury memory, language or reasoning skills is not required, but there must be a reasonable expectation of improvement that is of practical value to the individual, measured against the individual’s condition at the start of the rehabilitation program), and the individual must have no lasting or major treatment impediment that prevents progress such as severe dementia or aphasia; and
  • The individual is expected to show measurable functional improvement within a predetermined timeframe (depending on the underlying diagnosis/medical condition) from the start of cognitive rehabilitation therapy. Goals and expected timeframes should be addressed prior to the onset of treatment; and
  • The treating physician should review the treatment plan periodically to assess the continued need for participation and documented objective evidence of progress.

Note:  When cognitive rehabilitation is performed by a physical, occupational and/or speech therapist as part of thean outpatient rehabilitation/therapy program for patients who have suffered a stroke or traumatic brain injury, these services will be counted toward any applicable therapy visit limits in the member’s subscriber contract. 


A maintenance program consists of activities that preserve the patient’s present level of function and prevents regression of that function.  Maintenance begins when the therapeutic goals of a treatment plan have been achieved, or when no additional functional progress is apparent or expected to occur. Cognitive rehabilitation is considered not medically necessary when it becomes a maintenance program.


Cognitive rehabilitation is considered investigational for all other indications including but not limited to the following:

  • Alzheimer’s disease
  • Dementia
  • Parkinson’s disease
  • Huntington disease
  • Cognitive decline in multiple sclerosis and chronic obstructive pulmonary disease
  • Systemic lupus erythematosus
  • Anoxia/hypoxia, anoxic brain injury
  • Encephalitis
  • Toxic encephalopathy
  • Mental retardation
  • Cerebral palsy
  • Behavioral/psychiatric disorders to include but are not limited to:
    • Attention deficit/hyperactivity disorder
    • Depression
    • Schizophrenia
    • Social phobia
    • Substance abuse disorders
    • Pervasive developmental disorders including autism
  • Learning disabilities
  • Developmental delay
  • Autism spectrum disorder
  • Epilepsy or seizure disorders
  • Previous treatment of cancer
  • Patients with cognitive deficits due to brain tumor
  • Mild traumatic brain injury, including concussion
  • Decline in executive function (e.g. memory, organization, self-awareness…) not related to moderate or severe brain injury or stroke. 

Cognitive rehabilitation for coma stimulation, also called coma arousal program/therapy, sensory stimulation, and multi-sensory stimulation programs, for any indication, including coma or persistent vegetative state, because it is considered investigational.


Based on the peer reviewed literature there is insufficient evidence to support the use of cognitive rehabilitation in all other conditions except for traumatic brain injury and stroke as indicated above, medical literature is limited and available studies include small study samples and lack of comparison groups and long term follow up. Therefore, cognitive rehabilitation is considered investigational for all other indications except for traumatic brain injury and stroke as indicated above.
