Prognosis

CP is not a progressive disorder (meaning the actual brain damage does not worsen), but the symptoms can become worse over time due to 'subdual damage.' A person with the disorder may improve somewhat during childhood if he or she receives extensive care from specialists, but once bones and musculature become more established, orthopedic surgery may be required for fundamental improvement. People who have CP tend to develop arthritis at a younger age than normal because of the pressure placed on joints by excessively toned and stiff muscles.

The full intellectual potential of a child born with CP will often not be known until the child starts school. People with CP are more likely to have some type of learning disability, but this is not related to a person's intellect or IQ level. Intellectual level among people with CP varies from genius to mentally retarded, as it does in the general population, and experts have stated that it is important to not underestimate CP sufferer's capabilities and to give them every opportunity to learn.[25]

The ability to live independently with CP also varies widely depending on the severity of the disability. Some individuals with CP will require personal assistant services for all activities of daily living. Others can live semi-independently, needing support only for certain activities. Still others can live in complete independence. The need for personal assistance often changes with increasing age and associated functional decline. However, in most cases persons with CP can expect to have a normal life expectancy; survival has been shown to be associated with the ability to ambulate, roll, and self-feed.[citation needed] As the condition does not directly affect reproductive function, some persons with CP have children and parent successfully.

According to OMIM, only 2% of cases of CP are inherited (with glutamate decarboxylase-1 as one known enzyme involved.)[26] There is no evidence of an increased chance of a person with CP having a child with CP.
