Doctors are classified the cerebral palsy according to the involvement of the specific area of the brain that can cause following movement disorders:
- Muscle stiffness (spasticity)
- Abnormal movements (dyskinesia)
- Poor balance and coordination (ataxia)
On the basis of these disorders, it can be categorized into four main types, including:
Among all types, it is the most common type of cerebral palsy which affects about 80% of people.
People are suffering from spastic cerebral palsy have increased muscle tone. This leads to muscle stiffness, as a result of it, impairment of their body movements. Spastic cerebral palsy is further divided into three forms, depending on the affected parts of the body.
- Spastic Diplegic Cerebral Palsy―This type results from muscle stiffness mainly in the legs, arms with less affected or not affected at all. Difficulty in walking because of stretching of hip and leg muscles.This molds the legs turn inward or cross at the knees known as scissoring.
- Spastic Hemiplegic Cerebral Palsy ― In this type, cerebral palsy damages only one side of a person’s body. Typically, arms affect more than legs.
- Spastic Quadriplegic Cerebral Palsy ―This type is the last and most severe form of spastic cerebral palsy. It affects all four limbs, the trunk, and the face. People with such disabilities cannot walk and often have other developmental disabilities such as intellectual disability; seizures; or problems with vision, hearing, or speech.
Dyskinetic Cerebral Palsy
It is associated with athetoid, choreoathetoid, and dystonic cerebral palsies. People with dyskinetic CP have difficulties controlling the movement of their hands, arms, feet and legs. This makes it difficult to sit and walk. Also have slow, rapid or jerky movements.
Such types of cerebral palsy have balance and coordination problems. People with ataxic cerebral palsy have quick, jerky or unsteady uncontrollable movements. This makes it difficult for controlling hands or arms whenever they are trying to use it for multiple purposes.
Some people have more than one type of symptoms of cerebral palsy. It means they are showing multiple symptoms in which the most common is spastic-dyskinetic cerebral palsy.
