Cerebral Palsy
Aka: Cerebral Palsy- Epidemiology
- Incidence: Up to 2.5 per 1000 U.S. born children
- Pathophysiology
- Brain injury occurring before age 3 to 5 years
- Results in non-progressive disorder of movement and Posture
- Wide variability in disease involvement and in degree of intellectual capacity
- Causes
- Idiopathic in 25% of cases
- Prenatal causes or risk factors: Up to 80% of cases
- Delivery complications (i.e. asphyxia): 6% of cases
- Preterm birth before 32 weeks or <2500 grams
- Intrauterine Growth Retardation
- Intracranial Hemorrhage
- Teratogen Exposure
- Postnatal causes (<20%)
- Signs
- Limb spasticity (80% of cases)
- Hypertonic muscle movement
- Hyperreflexia
- Scissors gait
- Toe-walking
- Diskinesia (10-20% of cases)
- Slow, writhing limb movements worse during stress
- Ataxic Cerebral Palsy (5-10% of cases)
- Wide-based gait
- Intention Tremor
- Limb spasticity (80% of cases)
- Associated findings
- Cognitive Impairment (66% of cases)
- Motor Impairment
- Diplegia
- Hemiplegia
- Quadriplegia
- Seizure disorder (50-66% of cases, often spastic type)
- Growth delay
- Hearing Impairment
- Vision Impairment
- Screen for Strabismus and hemianopia
- Gastrointestinal disorders
- Vomiting (delayed gastric emptying)
- Constipation (GI motility, dehydration, mobility)
- Risk of sigmoid Volvulus
- Swallowing difficulty
- Aspiration risk
- Drooling
- Inadequate oral intake
- Osteoporosis
- Urinary Incontinence
- Altered sensory perception (pain on light touch)
- Diagnosis
- Assessment Tools
- Gross Motor Function Classification System for CP
- Findings suggestive of Cerebral Palsy
- Slow motor development
- Altered muscle tone and Posture
- Moro reflex persists beyond 6 months of age
- Dominant hand preference established under 12 months
- Findings of alternative diagnosis (neurodegenerative)
- Loss of acquired skills
- Atypical body odor (as seen in metabolic disorders)
- Loss of Deep Tendon Reflexes
- Assessment Tools
- Differential diagnosis
- Consider neurodegenerative disorders
- Examples
- Arginase deficiency
- Glutaric aciduria
- Niemann-Pick Disease
- Lesch-Nyhan Syndrome
- Rett Syndrome
- Management
- Global therapies with variable efficacy
- Neurodevelopmental treatment (Bobath method)
- Conductive education with rehabilitation program
- Physical therapy
- Balance benefit with stress of frequent visits
- Resistive Exercise is controversial
- Has been avoided due to increased spasticity risk
- Recent studies suggest strengthening is beneficial
- Medications: Spasticity
- Botulinum toxin (Botox) injections for leg spasticity
- Baclofen (Lioresal) intrathecally
- Medications: Pain (especially Hip Pain)
- Assess pain and treat adequately
- Seizures
- Emergent Seizure management is the same as for non-Cerebral Palsy patients
- Administer Benzodiazepines and Anticonvulsant loading
- Check Serum Glucose and anticonvulsant levels
- Other labs and diagnostic evaluation only as indicated by exam and history
- Seizures may be refractory to standard measures
- Combination antiepileptics are often required for Seizure control
- Consider ketogenic diet (risk of drug interactions)
- Emergent Seizure management is the same as for non-Cerebral Palsy patients
- Surgery
- Leg spasticity
- Selective dorsal rhizotomy
- Selective cutting of L1-S2 dorsal rootlets
- Selective dorsal rhizotomy
- Muscle imbalance with hip subluxation, dislocation
- Abduction bracing
- Soft tissue release
- Femoral or pelvic osteotomy
- Implantable stimulator to superior-medial Cerebellum
- Gastrostomy for swallowing and eating difficulties
- Leg spasticity
- Adjuncts
- Lower limb orthoses (variable evidence)
- Elastic body suits (difficult compliance)
- General measures
- Multidisciplinary approach (care team)
- Assistive Devices for Activities of Daily Living
- Enable mobility
- Address Mood Disorders
- Global therapies with variable efficacy
- Prevention: Secondary conditions
- Observe for cancers of higher risk in Cerebral Palsy
- Brain cancer
- Breast Cancer
- Routine health maintenance
- Left lateral position more comfortable for pelvic
- Educate about injury risks
- Drowning risk
- Motor vehicle accidents
- Observe for cancers of higher risk in Cerebral Palsy
