Cerebral palsy or CP is a group of permanent disorders associated with developmental brain injuries that occur during fetal development, birth, or shortly after birth. It is characterized by a disruption of motor skills, with symptoms such as spasticity, paralysis, or seizures.
Cerebral palsy is a form of static encephalopathy. One form of it, spastic diplegia, is sometimes known as Little's disease in the United Kingdom. Properly speaking, the fact that CP does not get better or worse (gait and posture can get worse over time if left untreated) implies that it is a 'condition' (chronic nonprogressive neurological disorder) rather than a 'disease.'
The incidence is about 1.5 to 4 per 1000 live births. There is no cure, but therapy has been shown to be helpful in the maintenance of motor functions. While severity varies widely, cerebral palsy ranks among the most costly congenital conditions to manage.
