Depending on the cause and severity, the symptoms of cerebral palsy may vary. The most common symptoms include stiffness, tightness, or spastic movement of the arms or legs. In more severe cases, the child may have limited mobility in crawling or reaching, or may have difficulty lifting his or her head without support.
There are also intellectual symptoms related to cerebral palsy, such as missed cognitive milestones, below average IQ, and behavioral problems. Some children with cerebral palsy also experience developmental delays.
