Cerebral palsy is caused by damage to the infant brain. This damage can involve not only the motor parts of the brain, but also the parts that deal with vision. This is not related to damage to the eye but is related to damage of the parts of the brain that process visual information.
Cerebral Palsy affects body movement, muscle control, muscle coordination, muscle tone, reflex, posture and balance. Depending on the part of the brain that is injured depends on how someone’s muscle tone will be effected. For people with spastic CP they have increased muscle tone because of the part of the brain that's injured. If causes very tight muscles which in turn effects the movement of the joints and of the limbs. For others who have dyskinetic CP they lose the ability to have voluntary control over their muscles, and they can have jerky and uncontrolled movement patterns.
