Cerebral Palsy is classified by the type of muscle movements that result from the brain injury and what activities the patient can perform. The following classification may help understand the different types of CP:
Spastic Cerebral Palsy
Approximately 80% of CP patients suffer from this syndrome. This type is characterized by high muscle tone causing stiff and jerky movements. Patient suffering from Spastic CP might display walking abnormalities, scissor shape appearance of legs (crossed always), tremors, slow movement and other developmental disabilities such as intellectual disability or similar. This can also be associated with muscle weakness or paralysis in some cases, which can be unilateral or bilateral.
Ataxic Cerebral Palsy
This involves the cerebellum part of brain damage hence has more to do with balance and co-ordination. Some might have a hard time with quick movements or movements that need a lot of control, like writing or drawing. In this type the muscle tone decreases causing inability to perform motor movements. Characterized by the movements that appear clumsy & jerky.
Dyskinetic Athetoid Cerebral Palsy
This disorder occurs when one looses control over the tone of muscle, causing spasms resulting in involuntary and abnormal movements. This type can be characterized by both hyper or hypotonia. This can affect all parts of the body, but in some cases, it’s localized in only one area of the body. Symptoms displayed also include: slow twitching and wriggling movements, drooling from lack of facial muscle control, difficulties with chewing, drinking, swallowing, and speech etc.
The last type is the ‘ Mixed Cerebral Palsy ‘ which often shows the combination of symptoms of all the above mentioned.
