Cerebral palsy, or cerebral palsy for short, is a combination of brain damage caused by a variety of different etiologies. It manifests as damage to the pyramidal tract and can also involve the extrapyramidal tract, cerebellum, and even the brainstem and spinal cord. The symptoms of cerebral palsy include motor disorders, postural disorders, language disorders, visual and auditory disorders, growth disorders, dental development disorders, orofacial dysfunction, emotional and behavioral disorders, and epilepsy. 1. Motor disorders: Children with cerebral palsy have lower motor ability than normal children of the same age and poor motor self-control. and swallowing. 2. Postural disorders: Children with cerebral palsy have abnormal body postures, poor postural stability, twisted postures 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 as in normal children, but used to lean to one side, or sway back and forth from side to side. 3. Intellectual disability: Among all children with cerebral palsy, about 1/4 of them have normal intellectual ability, about 1/2 of them have mild or moderate intellectual deficiency, and about 1/4 of them have severe intellectual deficiency. 4. Language disorder: Most of the children with cerebral palsy may have different degrees of language disorder, some of them show difficulty in expressing language or constructing language, some 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. Growth disorders: Some children with 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, good feelings and irritability, some are even withdrawn and do not get along. The abnormal behaviors are as follows: 1) Compulsive behavior: forcing themselves to do a certain action. (2) Self-injurious behavior: hitting oneself or hitting the wall with one’s head. (3) Aggressive behavior: beating 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 especially prominent in children with severe mental retardation.
