Neuropsychological (Cognitive) impairment
• Cognitive deficit after SAH is well known, but the neuropsychological outcome is underreported.
• Only 6.5% of studies reported the neuropsychological outcome
• Memory• Verbal memory - 14% to 61%
• Executive function• planning, inhibition, strategizing, problem solving, attention, and decision
making are impaired - 3% to 76%.
• Language• Various types 0% to 76%

Functional Outcome after SAH
• Activities of daily living (ADLs) 12%
• Instrumental activities of daily living (IADLs) 93%
• Unemployement 40-80% • return to previous occupation

Rehabilitation after SAH
Rehabilitation is the combined and co-ordinated efforts of a physician supervised multi-disciplinary team in helping a diseased person to reach maximum physical, psychological, social, vocational and educational potential, consistent with his or her physiological or anatomical impairment, environmental limitations, desires and life plans.

Early Rehabilitation – Mobilization Old paradigm - rehabilitation is the third phase of medicine
• Decrease in cerebral perfusion and leading to increase in DCI
• Fear of re-bleeding from another unsecured aneurysm
• Mobilization can negatively affect the development and course of cerebral vasospasm
New paradigm - rehabilitation should be initiated as early as possible• As soon as medically and
neurologically advisable, the patient should be mobilised out of bed and encouraged to ambulate if feasible with help of a physiotherapist
• Each step of mobilization during first 4 days after surgery reduces the risk of severe vasospasm

Inpatient Rehabilitation
Assessment [PULSES]• Physical condition• Upper extremities• Lower extremities• Sensory components related to speech, vision, and hearing system• Sphincter function• Sensorium (mental and emotional status)Any who has persistent and stable neurological deficit, and has impairment in
at least two key domains should be transferred to in patient neurorehabilitation facility

Integrated Neurorehabilitation Team • Rehabilitation Physician (Physiatrist).• Neuropsychologist.• Speech & language pathologist.• Physical therapist.• Occupational therapist.• Rehabilitation nurse.• Orthotist.• Social worker.• Access to other medical specialties as best available in the setting.

General Principles Rehabilitation
• Evaluation using FIM• Patient, family and caregiver education is provided • Meaningful, engaging, progressively adapted, task specific and goal-oriented
training to enhance sensory motor function• Training designed to simulate partial or whole skills required in ADL• Spasticity and contractures prevention and joint protection • Minimum 3 hours of daily rehabilitation therapies• The need for special equipment (e.g., wheelchairs, safety devices) should be
evaluated on an individual basis• Assessment should be done weekly

Principles of CRT
• Comprehensive neuropsychological assessment
• Hierarchy of CRT should address attention followed by memory then executive functions.
• A mix of restoration and compensation approaches should be used.• • The therapy should be systematic, structured and repetitive according
to the needs of each particular patient.

Efficacy of rehabilitation for SAH
• SAH patients receiving inpatient rehabilitation make significant functional gains, although the rate of gain is less than for TBI or stroke
• Recovery takes 3 months and continues till 18 months• SAH patients tend to have longer rehabilitation ward stays compared to
stroke or TBI patients • Early mobilization through aggressive rehabilitation programs has been
shown to improve cognitive function as well

Conclusion
The outcome after SAH is bad but is improving over years and can be better with neurorehabilitation
