Cerebral Palsy is an umbrella term covering a group of non-progressive and non-contagious motor conditions that cause physical disability in human development, mostly in the various area of body movement. Signs and symptoms of cerebral palsy usually show in the first year of life, sometimes even before birth.
The medical community has identified 3 types of cerebral palsy (however some people may have symptoms associated with different types, a condition known as mixed cerebral palsy.)
Spastic cerebral palsy causes great tension in the muscles. Normally, muscle groups work in pairs. When one pair tightens, the opposite pair relaxes. Interruptions in messages between the brain, nerves and muscles cause difficulty with movements.
Children with ataxic cerebral palsy usually walk with their feet far apart. They find it hard to move quickly or precisely. They have trouble writing or buttoning their clothes. Ataxic cerebral palsy also causes something called intention tremor. If a child with this symptom reaches for a book, his hand and arm start to quiver. The movement grows worse as he gets closer to the shelf.
Children with athetoid cerebral palsy have problems controlling the movement of their hands, arms, feet and legs. It can be hard to sit or walk. Their movements may be slow and writhing or rapid and jerky. If the face and tongue are affected, the person has a hard time sucking, swallowing and talking. Muscle tone can change from too tight to too loose.
