Cerebral palsy (CP) is a disorder that affects muscle tone, movement, and motor skills (the ability to move in a coordinated and purposeful way). Cerebral palsy can also lead to other health issues, including vision, hearing, and speech problems, and learning disabilities.
CP is usually caused by brain damage that occurs before or during a child's birth, or during the first 3 to 5 years of a child's life. There is no cure for CP, but treatment, therapy, and special equipment can help a child who is living with the condition. Cerebral palsy affects muscle control and coordination, so even simple movements like standing still are difficult. Other vital functions that also involve motor skills and muscles such as breathing, bladder and bowel control, eating, and learning may also be affected when a child has CP. Cerebral palsy does not get worse over time.
