Kids with CP have varying degrees of physical disability. Some have only mild impairment, while others are severely affected. This depends on the extent of the damage to the brain. For example, brain damage can be very limited, affecting only the part of the brain that controls walking, or can be much more extensive, affecting muscle control of the entire body.
The brain damage that causes CP can also affect other brain functions, and can lead to other medical issues. Associated medical problems may include visual impairment or blindness, hearing loss, food aspiration (the sucking of food or fluid into the lungs), gastroesophageal reflux (spitting up), speech problems, drooling, tooth decay, sleep disorders, osteoporosis (weak, brittle bones), and behavior problems.
Seizures, speech and communication problems, and mental retardation are more common among kids with the most severe forms of CP. Many have problems that may require ongoing therapy and devices such as braces or wheelchairs.
