Cerebral palsy (CP) is a group of permanent movement problemsthat do not get worse over time. They cause physical disability,[1]mainly in the areas of body movement.[2] There may also be problems with sensation, depth perception, and communication ability. Difficulty with cognition and epilepsy are found in about one third of cases. There are subtypes including a type characterized by spasticity, a type characterized by poor coordination, and types which feature both symptoms or neither.
Wiki上的解释是，主要损伤运动技能。1/3的案例伴有认知困难和癫痫。所以我收回我之前的话，不是所有的脑瘫儿都智力正常，是2/3的患者智力正常。 同时，我觉得百度上的“常伴有”是夸大的。
