Cerebral palsy is the term for a group of brain disorders that affect muscles and body movement. The condition is caused by damage to parts of the brain that control muscle movement, balance, and posture. Signs and symptoms of cerebral palsy usually appear in infancy or early childhood and last throughout a person's life. In most cases, the symptoms do not get worse over time.
Cerebral palsy is the most common movement disorder in children, according to the Centers for Disease Control and Prevention.1 The level and severity of disability caused by the condition differs from person to person. Some people with cerebral palsy may not be able to walk and need intensive, lifelong care, while others can walk and move with little or no help.2
