Forms of Cerebral Palsy: atheloid, ataxic, mixed, and spastic.
Mixed

In mixed cerebral palsy, symptoms do not fit neatly into one of the other classifications.  Different types of movement disorder may exist at the same time.  Generally, health care professionals will classify cerebral palsy according to the predominant type of motor impairment of the individual.  The classification can vary over time.  Because of this convention, the term is used less frequently than other descriptions.
The most common combination of types of cerebral palsy classified as mixed are spastic and athetoid.   In the case of this combination, there has been damage to both the cerebral cortex (spastic) and the basal ganglia (athetoid) areas of the brain.  Another type might include high muscle tone in some muscles and low muscle tone in others.
