What causes cerebral palsy and what exactly causes cerebral palsy

1.Progressive spinal muscular atrophy.

The disease begins in infancy, symptoms appear after more than 3 to 6 months, a small number of patients have abnormalities after birth, manifested as symmetrical weakness of the upper and lower limbs, progressive aggravation of muscle weakness, obvious muscle atrophy, tendon reflexes are reduced or disappeared, often due to respiratory muscle insufficiency and repeated respiratory tract infections, children cry lowly, cough weakness, muscle biopsy can help confirm the diagnosis, the disease is not combined with mental retardation, facial expression is alert, and eye movements are flexible.

2.Delayed motor development.

Some children, especially premature babies, are slightly less likely to develop motor development than their normal peers. However, it is not accompanied by abnormal muscle tone and postural reflexes, no abnormal movement patterns, and no other abnormal neurological reflexes. Symptoms of motor retardation may disappear in a short period of time as the child ages and focuses on exercise-oriented training.

What causes cerebral palsy.

3.Congenital muscle flaccidity.

Immediately after birth, the child has significant hypotonia, muscle weakness, and low or absent deep tendon reflexes. Respiratory tract infections are often prevalent. It is sometimes misdiagnosed as hypotonic cerebral palsy, but the latter tendon reflex is usually eliminated.

Cerebral palsy is complex and includes both hereditary and acquired factors. The latter is divided into prenatal, perinatal and neonatal factors, and some cases have not yet been clear.

At present, it is believed that the four important factors associated with the development of cerebral palsy are preterm birth or low birth weight, neonatal asphyxia or neonatal ischemic-hypoxic encephalopathy, neonatal hyperbilirubinemia, and intrauterine infection. In addition, the occurrence of cerebral palsy is also related to genetic factors.

What are the ** of cerebral palsy?

Prenatal factors.

The quality of the conceived embryo.

Parental smoking, alcohol, or drug abuse before and after pregnancy can affect embryo quality.

Mother's physical condition.

Factors such as infection, poisoning, and exposure to radiation during the first trimester of pregnancy can lead to poor brain cell development.

Perinatal factors.

Premature birth. It can lead to a variety of pathologies, and children are more likely to have cerebral palsy.

Birth trauma. Sudden labor, suction delivery, and forceps may result in intracranial hemorrhage.

Anoxia. Factors such as prolonged delivery, umbilical cord around the neck, meconium aspiration, and poor placental function lead to fetal cerebral hypoxia.

Hyperbilirubinemia.

Bilirubin over 20 mg dl can lead to neonatal bilirubin encephalopathy (kernicterus) when bilirubin exceeds 20 mg dl.

Neonatal factors.

Cerebral palsy can be caused by various infections, severe asphyxia, brain trauma, and intracranial hemorrhage caused by neonatal hemorrhage.

Genetic factors. Some children with cerebral palsy may have a family history of genetic disease, and if the child has a close relative who has epilepsy, cerebral palsy, or intellectual disability, the probability of cerebral palsy is increased.

**。Risk factors for cerebral palsy mainly occur in neonates with one or more factors such as hypoxic-ischemic encephalopathy, preterm birth, hyperbilirubinemia, and intracranial hemorrhage, and some of them may develop cerebral palsy.
