Cerebral palsy is a non-progressive disorder affecting movement and posture, often with associated epilepsy, vision, speech, and intellectual impairments, resulting from brain lesions or defects during development. It is the most common motor disability in childhood, affecting 2-2.5 per 1,000 children in the US. Causes include prematurity, genetic factors, infections, and brain injuries during prenatal, perinatal, or postnatal periods. Common types are spastic diplegia, hemiplegia, and quadriplegia. Diagnosis involves assessing abnormal movements, tone, reflexes and ruling out other causes through history and examination.
