What types of cerebral palsy are there?

Spastic cerebral palsy: People with spastic cerebral palsy have increased muscle tone. Their muscles are stiff. Their movements can be awkward. Seventy to eighty percent of people with cerebral palsy have spasticity. Spastic cerebral palsy is usually described further by what parts of the body are affected. In spastic diplegia, the main effect is found in both legs. In spastic hemiplegia, one side of the person's body is affected. Spastic quadriplegia affects a person's whole body (face, trunk, legs, and arms).

Athetoid or dyskinetic cerebral palsy: People with athetoid cerebral palsy have slow, writhing movements that they cannot control. The movements usually affect a person's hands, arms, feet, and legs. Sometimes the face and tongue are affected and the person has a hard time talking. Muscle tone can change from day to day and can vary even during a single day. Ten to twenty percent of people with cerebral palsy have the athetoid form of the condition.

Ataxic cerebral palsy: People with ataxic cerebral palsy have problems with balance and depth perception. They might be unsteady when they walk. They might have a hard time with quick movements or movements that need a lot of control, like writing. They might have a hard time controlling their hands or arms when they reach for something. People with ataxic cerebral palsy can have increased or decreased muscle tone. Five to ten percent of people with cerebral palsy have ataxia.

Mixed cerebral palsy: Some people have more than one type of cerebral palsy. The most common pattern is spasticity plus athetoid movements.
