What is Cerebral Palsy?

According to the Mayo Clinic, cerebral palsy (CP) is a “disorder of movement, muscle tone or posture that is caused by damage that occurs to the immature, developing brain, most often before birth.” The signs and symptoms of CP can vary greatly and appear during infancy or preschool years. Signs and symptoms of CP include problems with swallowing, eye muscle imbalance, reduced range of movement due to muscle stiffness, floppiness or rigidity of the limbs and trunk, abnormal posture, unsteady walking or a combination of these.

CP’s effect on functional abilities varies greatly, and each person may be affected differently. Some people with CP can walk without a mobility device, some may use a walker, and some may use a wheelchair. Some may have intellectual or developmental disabilities, while others do not. Some people with CP may experience seizures. Others may have sensory disabilities.

According to the Centers for Disease Control and Prevention (CDC), the “brain damage that leads to CP can happen before birth, during birth, within a month after birth, or during the first years of a child’s life, while the brain is still developing.” There are two types of CP: Congenital, which occurs before or during birth, and Acquired, which occurs more than 28 days after birth. Congenital CP accounts for 85-90% of cases and, in many of these cases, the cause is not known. Risk factors for congenital CP include low birthweight, premature birth, assisted reproductive technology infertility treatments, infections during pregnancy, jaundice and kernicterus experienced by the child, medical conditions of the mother, and birth complications. Acquired CP accounts only for a small percentage of cases and is usually associated with an infection, such as meningitis; a head injury; or a problem with blood flow to the brain. The risk factors of acquired CP include infancy as infants are at greater risk of a brain damaging event than older children, preterm or low birthweight, brain infections, and a brain injury.

To Learn More About Cerebral Palsy

Along with the Mayo Clinic and the CDC, the following organizations also provide information:

In its 40 year history, NIDILRR has funded over 60 projects researching topics related to CP, including dynamic supported mobility for infants and toddlers with CP, walking and its effect on the health and function of people with CP as they transition to adulthood, and a brain-computer interface to operate a commercial augmentative and alternative communication system. NARIC’s information specialists searched REHABDATA and found articles on CP from the NIDILRR community and beyond.

Please Note: If you think your child may have CP, please contact your child’s pediatrician for more information on testing and diagnosis.
