So what does 'mixed spastic dystonic quadriplegia cerebral palsy' mean? If you want to know what cerebral palsy is click here

Cerebral palsy is classified by how it effects a persons nervous system and if it effects their face, arms, trunk, or legs. Micah has mixed C.P. that means that he has a combination of two or more disorders. This is because both the pyramidal (area of the brain that controls voluntary movements [the motor cortex]) and the extrapyramidal areas of the brain are injured. The extrapyramidal is the area of the cerebellum or the basal ganglia that normally process the signals from the motor cortex. 
Spastic C.P. results when the pyramidal part of the brain is injured. It is the most common type of C.P. Spastic C.P. is classified by having tight or contracted muscle groups that limit movement.
Dystonic is a term to describe one of the involuntary movements that are associated with extrapyramidal C.P. Dystonic or Dystonia is a slow, rhythmic, twisting movement of the trunk, or an arm and/or leg. The doctors say that Micah has Dystonia although he doesn't seem to fit this description. This is one reason we got a Baclofen pump.
Quadriparetic or Quadriplegia, is when C.P. affects the child's entire body, face, arms, trunk, and legs. Usually the persons feet and legs are affected most, having a high muscle tone or involuntary movements. Because it affect their face they usually have speech and feeding difficulties.
