a cerebral palsy is a group of disorders that affect movement and muscle tone or posture. It’s caused by damage that occurs to the immature brain as it develops, most often before birth. Signs and symptoms appear during infancy or preschool years. The cause of cerebral palsy is a brain injury or brain malformation that occurs while the brain is developing — before, during, or after birth. As a result of brain damage during brain development a child’s muscle control, muscle coordination, muscle tone, reflex, posture, and balance can be affected. Although there have been no general studies of life expectancy in people with cerebral palsy, most children affected by CP live between 30 and 70 years, depending on the severity of the condition. In general, a child with a mild case of CP usually lives longer than a child with mobility and intellectual limitations.
1 in 2 people with cerebral palsy has an intellectual disability. 1 in 5 people has a moderate to severe intellectual disability. Generally, the greater the level of a person’s physical impairment, the more likely it is that they will have an intellectual disability.
Signs and Symptoms of Cerebral Palsy
Cerebral palsy (CP) is a group of permanent movement disorders that appear in early childhood. Signs and symptoms vary among people and over time. Often, symptoms include poor coordination, stiff muscles, weak muscles, and tremors. There may be problems with sensation, vision, hearing, swallowing, and speaking. Often, babies with cerebral palsy do not roll over, sit, crawl or walk as early as other children of their age. Other symptoms include seizures and problems with thinking or reasoning, which each occur in about one-third of people with CP. While symptoms may get more noticeable over the first few years of life, underlying problems do not worsen over time.
