Most of the children have cognitive dysfunction, few have motor disorders, some of them show progressive aggravation, there are obvious gender differences, although the cause is unknown, but I tend to metabolism or certain enzyme abnormalities, the focus of treatment should be on the development of the child’s ability to live or survive, and develop the functions that already exist in the brain, for some hyperactive and progressive aggravation of the child, it is recommended to do dynamic electroencephalography. The presence of epilepsy cannot be ignored, and may be the malady of a small seizure with epileptic disorientation. Treatment is commonly used with various training, partly with biological therapies such as detoxification, and hyperbaric oxygen is helpful to improve cognition. Second, cerebral palsy: It is pointed out that chronic non-progressive brain injury that occurs before birth or within one month after birth, mainly manifests as central motor impairment or postural abnormalities. There are many causes of cerebral palsy, including prematurity accounting for about 60%, other causes include asphyxia, hemorrhage, nuclear jaundice, genetics, infection, etc. In mild cases, the heel cannot touch the ground when walking (also called pointed foot), and in severe cases, both lower limbs are paralyzed or quadriplegia. The prognosis of cerebral palsy is relatively poor. At present, there are massage, training, acupuncture, hyperbaric oxygen, buried thread, surgery and other treatment methods. However, clinically it is difficult for doctors to arbitrarily diagnose cerebral palsy in children before the age of 2. Perhaps the child is born late in talking and walking, so doctors are more used to using neurodevelopmental delay as the conclusion, which is manifested as a decrease in motor function, cognitive function, language and other abilities in different degrees. Hyperbaric oxygen, drugs, training are good choices, acupuncture, massage is less significant, the prognosis is relatively good. Hypoxic encephalopathy: Here mainly refers to the organic or functional brain changes caused by epilepsy, trauma, infection, asphyxia, etc. The focus is on the treatment of the original disease, while paying great attention to the rehabilitation of brain function. The above four conditions have some cross symptoms, parents should focus in their hearts, especially those with poor cognitive function. Generally children’s brain development is basically set by the age of 6-7 years old, before which the time for treatment should be seized, early detection, early intervention and early treatment are the basic principles. Parents are opposed to follow the trend, must choose the right treatment for the child according to the child’s situation, in principle, comprehensive intervention is better than a single treatment, diet, eat more dried fruit food, can not ignore the role of hyperbaric oxygen, drugs.
