Cerebral palsy is a syndrome of postural and motor dysfunction caused by non-progressive brain injury during the immature stage of brain development from pregnancy to the first month of life. Cerebral palsy is a common syndrome of central nervous system disorder in pediatric period, with lesions in the brain, involving the limbs, and various manifestations, including mental retardation, convulsions, hearing and visual impairment, and behavioral abnormalities. Symptoms of cerebral palsy 1. Motor disorders: The motor ability of children with cerebral palsy is lower than that of normal children of the same age, and the motor self-control ability is poor. 2. Postural disorders: Children with cerebral palsy have abnormal body posture, poor postural stability, twisted posture during movement or at rest, asymmetry between the left and right sides, and in some severe cases, the head is often not in a vertical and central position like normal children, but is used to leaning to one side, or swaying back and forth. 3. Intellectual disability: Among all children with cerebral palsy, about 1/4 of them have normal intelligence, about 1/2 of them have mild or moderate intelligence deficiency, and about 1/4 of them have severe intelligence deficiency. 4. Language disorder: Most children with cerebral palsy may have different degrees of language disorder, some of them show difficulty in expressing language or constructing language, some of them show difficulty in pronunciation or stuttering, and some of them also show Some of them may have aphasia, that is, they can understand other people’s language, but they cannot speak by themselves. Many children with cerebral palsy have myopia or strabismus, with internal strabismus being the most common, and hearing loss is more common in tachycardia. Children with cerebral palsy often have difficulty in recognizing the rhythm of sounds. 6. Growth disorders: Some children with mild cerebral palsy may have basic or near normal growth and development, but most children with cerebral palsy are shorter than normal children of the same age and appear to be behind in growth and development. Most of the children with cerebral palsy have poorly developed teeth, with loose and easily decayed teeth, and the incidence of various dental diseases is higher than normal children. 8. Oral and facial dysfunction: Some children with cerebral palsy have obvious spasms or uncoordinated contractions of the facial muscles and tongue muscles. This leads to difficulty in chewing and swallowing, difficulty in closing the mouth and drooling. 9. Emotional and behavioral disorders: Many children with cerebral palsy, especially those with tardive dyskinesia, have stubborn and capricious personalities, with large changes in mood swings and irritability, and some are even withdrawn and do not get along with others. Abnormal behaviors may include: (1) Compulsive behavior: Forcing oneself to perform a certain action. (2) Self-injurious behavior: hitting oneself or banging one’s head against the wall constantly. (3) Aggressive behavior: hitting others, but it is less common. 10. Epilepsy: About 39% – 50% of children with cerebral palsy have epilepsy induced by fixed lesions in the brain, and the incidence of epilepsy is particularly prominent in children with severe mental retardation.
