Cerebral Palsy (CP) is a group of disorders that affect a persons ability to move and maintain balance and posture. It is the most common motor disability in childhood, affecting about 1 in 345 children. The term "cerebral" refers to the brain, while "palsy" means weakness or problems with using the muscles. CP is caused by damage to the developing brain during pregnancy, birth, or shortly after birth. The signs of CP vary greatly because there are many different types and levels of disability. The main sign that a child might have CP is a delay reaching motor or movement milestones (such as rolling over, sitting, standing, or walking) . Some other signs of possible CP include stiff muscles, lack of balance and muscle coordination, jerky movements, and trouble walking. After a CP diagnosis is made, a team of health professionals works with the child and family to develop a plan to help the child reach his or her full potential. Common treatments include medicines, surgery, braces, and physical, occupational, and speech therapy.
