Definition of Cerebral Palsy (CP)

Cerebral Palsy (CP) is a group of permanent movement disorders that appear in early childhood. It is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. The severity of CP varies widely among individuals, from mild to severe.

The word "cerebral" refers to the brain's cerebrum, which is the part of the brain that regulates motor function. "Palsy" describes the paralysis of voluntary movement in certain parts of the body.

Important Facts About Cerebral Palsy

• There is no cure, but treatments can help improve function
• Symptoms may vary during the child's development
• The condition doesn't get worse over time
• It's the most common motor disability in childhood
• Affects about 1 in 345 children (CDC estimate)

Symptoms of Cerebral Palsy

Symptoms appear during infancy or preschool years and vary from very mild to serious:

Movement Symptoms

• Exaggerated reflexes
• Stiff muscles (spasticity)
• Floppy arms, legs and trunk
• Irregular posture
• Uncontrolled movements
• Unsteady walk

Other Symptoms

• Difficulty swallowing
• Eye muscle imbalance
• Reduced range of motion
• Speech delays
• Intellectual disability (some cases)
• Epilepsy (some cases)

The cause of cerebral palsy and its effect on function vary from person to person. Some people with cerebral palsy can walk while others need assistance. Some have intellectual disabilities, but others do not. Epilepsy, blindness or deafness also might affect some people with cerebral palsy.

Types of Cerebral Palsy

Type	Description	Prevalence
Spastic CP	Characterized by stiff and difficult movements due to increased muscle tone (spasticity). It is the most common type and can affect one or more limbs.	~80% of cases
Dyskinetic CP	Involves uncontrolled, involuntary movements. This type can cause slow, writhing movements (athetosis) or rapid, jerky movements (chorea).	~6% of cases
Ataxic CP	Results in problems with balance and coordination. Individuals may have shaky movements or difficulty with precise movements.	~6% of cases
Mixed CP	A combination of symptoms from the above types, where no single type is predominant.	~8% of cases

Spastic CP Subtypes

By Limbs Affected

• Hemiplegia: One side of body affected (arm and leg on same side)
• Diplegia: Mostly legs affected (arms less affected or unaffected)
• Quadriplegia: All four limbs affected (most severe form)
• Monoplegia: Single limb affected (rare)

By Muscle Tone

• Spastic: Stiff, tight muscles (most common)
• Hypotonic: Low muscle tone (floppy appearance)
• Dystonic: Mixed muscle tone (fluctuates between stiff and floppy)
• Athetoid: Uncontrolled writhing movements

Causes & Prevention

Prenatal Causes (Before Birth)

• Maternal infections (rubella, cytomegalovirus, toxoplasmosis)
• Exposure to toxins (alcohol, drugs, certain medications)
• Genetic mutations and disorders
• Placental problems affecting oxygen/nutrient supply
• Brain malformations during development
• Maternal health conditions (thyroid disorders, seizures)

Perinatal Causes (During Birth)

• Birth asphyxia (lack of oxygen during delivery)
• Premature birth (before 37 weeks gestation)
• Low birth weight (less than 5.5 pounds)
• Birth trauma (physical injury during delivery)
• Severe jaundice (kernicterus causing brain damage)
• Multiple births (twins, triplets)

Postnatal Causes (After Birth)

• Brain infections (meningitis, encephalitis)
• Head injuries (traumatic brain injury)
• Stroke (blood clot or bleeding in brain)
• Near-drowning incidents
• Severe untreated jaundice
• Poisoning or toxin exposure

Prevention Strategies

Before Pregnancy

• Complete all recommended vaccinations
• Manage chronic health conditions (diabetes, hypertension)
• Genetic counseling for high-risk families
• Maintain healthy weight and nutrition
• Avoid alcohol, tobacco and illicit drugs

During Pregnancy

• Regular prenatal care and checkups
• Prevent infections (good hygiene, safe food handling)
• Monitor for and treat high blood pressure
• Avoid exposure to toxins and chemicals
• Manage gestational diabetes if it develops

After Birth

• Newborn screening for treatable conditions
• Monitor and treat jaundice promptly
• Use car seats properly to prevent head injury
• Vaccinate according to schedule
• Childproof home to prevent accidents

Educational Implications

Supporting Students with Cerebral Palsy

Inclusive Education

• Mainstream classrooms with appropriate supports
• Peer buddy systems
• Universal design for learning principles
• Social inclusion programs

Individualized Plans

• Individualized Education Programs (IEPs)
• 504 Plans for accommodations
• Transition planning for adulthood
• Regular progress monitoring

Assistive Technologies

• Communication devices (AAC)
• Adaptive computers/tablets
• Specialized writing tools
• Voice recognition software

Physical Accessibility

• Wheelchair ramps and elevators
• Adaptive restrooms
• Wider doorways and hallways
• Specialized classroom furniture

Management of Cerebral Palsy

Medical Treatments

• Muscle relaxants: Baclofen, Diazepam
• Anti-spasticity injections: Botox, Phenol
• Pain management: NSAIDs, other analgesics
• Anti-seizure medications: For epilepsy
• Orthopedic surgery: For contractures/scoliosis
• Selective dorsal rhizotomy: Nerve surgery

Therapies

• Physical therapy: Improves mobility, strength
• Occupational therapy: Daily living skills
• Speech therapy: Communication/swallowing
• Aquatic therapy: Water-based exercises
• Constraint therapy: For hemiplegia
• Hippotherapy: Therapeutic horseback riding

Assistive Devices

• Mobility aids: Walkers, wheelchairs, standers
• Orthotics: Braces, splints, shoe inserts
• Communication devices: AAC systems
• Adaptive equipment: Special utensils, writing tools
• Home modifications: Ramps, grab bars
• Vehicle adaptations: Hand controls, lifts

Additional Support Services

Psychological Support

• Counseling for emotional wellbeing
• Support groups for families
• Sibling support programs
• Stress management techniques

Community Resources

• Early intervention programs
• Recreational therapy programs
• Respite care services
• Vocational training

Nutritional Support

• Feeding therapy
• Dietician consultations
• Special diets for constipation
• Tube feeding if needed

Living with Cerebral Palsy

While cerebral palsy is a lifelong condition, early intervention and proper management can significantly improve quality of life. With the right support - medical care, therapies, assistive technologies, and inclusive education - individuals with cerebral palsy can lead fulfilling lives and achieve their personal goals.

Many adults with CP complete higher education, maintain employment, live independently, and participate fully in their communities. Advances in medical care, technology, and social inclusion continue to improve outcomes for people with CP across the lifespan.
