USMLE Guide: Cerebral Palsy

Introduction

Cerebral Palsy (CP) is a group of permanent movement disorders that appear in early childhood. It is caused by damage or abnormal development of the brain, affecting a person's ability to control their muscles. CP is a non-progressive condition, meaning it does not worsen over time, but the symptoms can change over a person's lifetime.

Types of Cerebral Palsy

  1. Spastic CP: This is the most common type of CP, characterized by increased muscle tone, stiffness, and difficulty with movement.
  2. Dyskinetic CP: This type involves uncontrolled, involuntary movements, such as twisting or writhing motions.
  3. Ataxic CP: Ataxic CP affects balance and coordination, leading to shaky or unsteady movements.
  4. Mixed CP: Some individuals may have a combination of the above types.

Etiology

  1. Prenatal Causes: Maternal infections, drug or alcohol use, exposure to toxins, or maternal medical conditions during pregnancy.
  2. Perinatal Causes: Premature birth, low birth weight, lack of oxygen during birth, or trauma during delivery.
  3. Postnatal Causes: Infections, head injuries, or medical conditions after birth that result in brain damage.

Clinical Presentation

  1. Delayed Milestones: A child with CP may not reach developmental milestones like rolling over, sitting, crawling, or walking at the expected age.
  2. Abnormal Muscle Tone: Spasticity, rigidity, or floppiness of the muscles may be observed.
  3. Impaired Motor Function: Difficulty with voluntary movement, poor coordination, tremors, or involuntary movements.
  4. Abnormal Reflexes: Overactive or absent reflexes, such as the Moro reflex or tonic neck reflex.
  5. Gait Disturbances: Walking abnormalities like toe-walking, a crouched gait, or an asymmetrical gait.

Diagnosis

  1. Clinical Evaluation: Detailed history, physical examination, and developmental assessment.
  2. Neuroimaging: Magnetic Resonance Imaging (MRI) to identify any brain abnormalities or lesions.
  3. Electroencephalogram (EEG): To evaluate for seizures or abnormal brain activity.
  4. Genetic Testing: In cases where a genetic cause is suspected.

Management

  1. Multidisciplinary Approach: A team including physicians, physical therapists, occupational therapists, speech therapists, and social workers work together to manage CP.
  2. Physical Therapy: Exercises and stretches to improve muscle strength, flexibility, and coordination.
  3. Occupational Therapy: Activities to enhance fine motor skills, self-care abilities, and adapt to the environment.
  4. Speech Therapy: Techniques to improve speech, communication, and swallowing difficulties.
  5. Medications: Antispasmodic medications, muscle relaxants, or botulinum toxin injections may be used to manage spasticity.
  6. Surgical Interventions: In severe cases, orthopedic surgeries may be performed to correct skeletal deformities.

Prognosis

  1. Varies Widely: The prognosis depends on the severity of CP and the individual's access to early intervention and ongoing care.
  2. Life Expectancy: Most individuals with CP have a normal lifespan.
  3. Quality of Life: With proper management and support, individuals with CP can lead fulfilling lives and achieve their potential.
