Does cerebral palsy get worse over time?

Generally not: By definition the injury causing CP creates a stable effect; that is you do not see deterioration of skills after they are acquired. Some nervous system disorders get worse with age as the injury is continuing, not cp. Some CP patients may choose a wheel chair later in life although they can still walk some for the convenience & speed. Most CP kids actually will get better over time with therapy.

It should not: Cerebral palsy by definition is a static encephalopathy. This means that it is a stable condition that just needs help to overcome. If there is progressive loss of function, then some other diagnosis must be considered. In some patients the back, hips, ankles get tighter and contracted. This is not worse disease but just progression of the spasticity.
