Cerebral palsy is a group of disorders that affect movement and posture, caused by non-progressive damage to the developing brain before or after birth. It is diagnosed when brain damage occurs prenatally from conception to labor onset, perinatally from 28 weeks gestation to 7 days after birth, or postnatally in the first 2 years of life. The prevalence is 1-5 per 1000 live births globally and 2-2.5 per 1000 in Western countries. Etiology includes prematurity, low birth weight, infections, trauma, and complications during pregnancy, labor, or delivery. Early identification is based on risk factors and developmental delays. Diagnosis usually occurs between ages 2-5 years through
