Cerebral Palsy

Cerebral palsy, the most common motor disability in childhood, stems from brain damage or abnormal development before, during, or shortly after birth, impacting movement and posture.

Neurologic
Cerebral palsy is a group of disorders that affect a person's ability to move and maintain balance and posture. Cerebral palsy is the most common motor disability in childhood. "Cerebral" means having to do with the brain, and "palsy" means weakness or problems with using the muscles. It is caused by abnormal brain development or damage to the developing brain that occurs before birth, during birth, or within a few years after birth. Causes: Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. The brain damage can occur at various stages:
  • Prenatal (before birth):
    • Maternal infections: Infections during pregnancy (e.g., rubella, cytomegalovirus, toxoplasmosis, Zika virus) can cause brain damage in the developing fetus.
    • Fetal stroke: A disruption of blood supply to the developing brain.
    • Lack of oxygen to the brain (fetal hypoxia): Can occur due to problems with the placenta or umbilical cord.
    • Genetic mutations: Rare genetic factors can lead to abnormal brain development.
    • Severe jaundice: Untreated jaundice in a newborn can lead to brain damage (kernicterus).
    • Exposure to toxins: Maternal exposure to certain toxins or substances.
  • Perinatal (during birth):
    • Complications during labor and delivery: Although less common than once thought, a lack of oxygen during a difficult or prolonged birth can cause brain damage.
    • Premature birth: Babies born prematurely are at higher risk, partly because their brains are not fully developed and are more vulnerable to injury.
    • Low birth weight: Babies with very low birth weight are at increased risk.
  • Postnatal (after birth, usually within the first few years):
    • Severe infections: Infections like meningitis or encephalitis can cause brain inflammation and damage.
    • Head injury: Traumatic brain injury from accidents or abuse.
    • Stroke: A stroke occurring in infancy or early childhood.
    • Severe dehydration or electrolyte imbalances.
Symptoms: The signs and symptoms of cerebral palsy vary greatly among individuals, depending on the location and severity of the brain damage. They typically appear during infancy or preschool years and can include:
  • Motor skill delays:
    • Not reaching developmental milestones like rolling over, sitting up, crawling, or walking at typical ages.
    • Difficulty with fine motor skills (e.g., picking up small objects).
  • Abnormal muscle tone:
    • Spasticity (most common): Stiff muscles and exaggerated reflexes, leading to awkward movements.
    • Athetosis / Dyskinetic Cerebral Palsy: Uncontrolled, slow, writhing movements.
    • Ataxia: Problems with balance and coordination, leading to unsteady walking.
    • Hypotonia: Floppy muscle tone.
  • Movement difficulties:
    • Walking difficulties (e.g., walking on toes, a crouched gait, or a scissored gait).
    • Favoring one side of the body.
    • Difficulty with precise movements.
  • Other associated conditions:
    • Speech difficulties (dysarthria)
    • Swallowing problems (dysphagia)
    • Intellectual disabilities
    • Seizures
    • Vision problems (e.g., strabismus, amblyopia)
    • Hearing impairment
    • Pain
    • Bladder and bowel control issues
    • Dental problems
Diagnosis: Diagnosing cerebral palsy involves assessing a child's development and ruling out other conditions. Diagnosis often occurs between 12 and 24 months of age, but can be later for milder cases.
  • Developmental monitoring: Regular checks of a child's growth and development during routine check-ups.
  • Developmental screening: Short tests to identify developmental delays.
  • Developmental and neurological assessment: A more in-depth evaluation by a specialist (e.g., neurologist, developmental pediatrician) to assess motor skills, reflexes, and muscle tone.
  • Brain imaging:
    • MRI (Magnetic Resonance Imaging): The preferred imaging test to identify brain damage or abnormalities.
    • CT scan (Computed Tomography): Less commonly used but can also show brain abnormalities.
    • Cranial ultrasound: May be used for infants, especially premature babies, to detect brain abnormalities.
  • Electroencephalogram (EEG): If seizures are suspected.
  • Genetic testing: To rule out other genetic conditions that might cause similar symptoms.
Treatment: There is no cure for cerebral palsy, but treatment focuses on managing symptoms, improving function, and enhancing quality of life. Management is typically lifelong and involves a multidisciplinary team.
  • Therapies:
    • Physical therapy: To improve muscle strength, flexibility, balance, and motor skills.
    • Occupational therapy: To help with daily living activities (e.g., dressing, eating, writing).
    • Speech and language therapy: To improve communication, swallowing, and feeding difficulties.
    • Recreational therapy: To promote participation in leisure activities.
  • Medications:
    • Muscle relaxants: To reduce spasticity (e.g., baclofen, tizanidine, diazepam). Can be oral or delivered via an intrathecal pump.
    • Botulinum toxin (Botox) injections: To relax specific spastic muscles.
    • Anti-seizure medications: To control seizures.
    • Pain medications: To manage chronic pain.
  • Surgical interventions:
    • Orthopedic surgery: To lengthen muscles, correct bone deformities, or release tendons to improve mobility and reduce pain.
    • Selective dorsal rhizotomy (SDR): A procedure that involves cutting specific nerve roots in the spinal cord to reduce severe spasticity in the legs.
  • Assistive devices:
    • Braces, splints, or orthotics to support limbs and improve posture.
    • Walkers, crutches, or wheelchairs for mobility.
    • Communication devices (e.g., speech-generating devices).
  • Nutritional support: For those with swallowing difficulties, feeding tubes may be necessary to ensure adequate nutrition.
Early intervention is key to maximizing a child's potential. A personalized treatment plan is developed and adjusted as the child grows and their needs change.
