If a doctor diagnoses a child with “cerebral palsy,” most people would consider the child to be a total loss, while saying that the child is “developmentally delayed” or “psychomotor delayed” would be less of a concern. Most people would think that the child is completely disabled, and say that the child is “developmentally delayed” or “psychomotor retarded”, so they would not worry too much. In reality, the situation is not as simple as this. The reason for this misunderstanding is that people only take the above diagnosis literally and do not have a clear understanding of its meaning. I saw a TV program talking about Wang Ji’s mentally handicapped son and they, like them, thought that cerebral palsy was more serious and difficult than intellectual disability or autism. Here is what to know when lifting this misconception and concept. I. Cerebral palsy: Cerebral palsy is a central motor disorder caused by brain injury, which can be accompanied by intellectual backwardness, epilepsy, and visual and hearing impairment.” The term “palsy” refers to motor impairment, and this motor impairment is caused by brain damage, a condition similar to stroke in adults. Mental abnormalities in cerebral palsy account for about 60% to 75%, which means that 25% to 40% of intelligence is in the normal range; with epilepsy there are 10% to 40%. A small number of children with cerebral palsy have severe cerebral palsy, or “total cerebral disability”, which is usually understood literally, accounting for less than 30% of cerebral palsy. Children with mild cerebral palsy can have good intelligence, so it is easy to be ignored at an early stage and delay treatment to some extent. Psychomotor retardation: Psychomotor retardation in infancy is often associated with mental retardation later in life. Mental retardation is a symptom of abnormal brain function during the developmental period, with mild mental retardation accounting for 40% to 55% and the rest being moderate and severe. Mild mental retardation, in addition to developmental delay, often no clinical special performance, most can not find the cause, EEG, head magnetic resonance can not find abnormalities, and therefore most likely to be ignored by parents. Even in severe cases, the cause is unknown in 20% to 30% of cases. The incidence of mental retardation is 1.5%-2%, which means that there are 15-20 children with mental retardation out of 1000 children. This number is 10 times greater than the incidence of cerebral palsy. It is more important to pay attention to it. Early and aggressive intervention can improve the prognosis.
