Cerebral Palsy (CP)

What Is Cerebral Palsy ...?

Cerebral palsy (CP) is a group of motor problems and physical disorders that result from a brain injury or abnormal brain development and that may occur during fetal growth, at the time of birth, or within the first 2 or 3 years of a child's life. The brain injury that causes CP does not get worse over time, but symptoms may begin, change, or become more severe as a child grows.


Cerebral palsy can affect the muscles of a part or side of the body, or sometimes the whole body. Uncontrolled reflex movements and muscle spasticity (tightness) occur with varying severity. Physical problems of cerebral palsy range from mild (a clumsy walk) to severe (an inability to control movement of the arms, legs, or muscles of the mouth and tongue). People with severe forms of cerebral palsy are more likely to have other problems, such as seizures or mental retardation.

Sometimes the exact cause of cerebral palsy is known, such as when brain damage follows a serious infection or head injury. In many cases the exact cause of cerebral palsy is not known.
