Slow brain development

Introduction The slow development of the brain is mainly characterized by mental retardation. The child may have the following medical history: the parents are married to close relatives; the mother is pregnant under the age of 16 or over 40; the mother has hypertension, diabetes, thyroid disease; the mother has a history of viral infection in early pregnancy; the mother has a habitual abortion, Threatened abortion, pregnancy-induced hypertension, and polyhydramnios history; the production process is premature delivery, emergency production, induction of labor, caesarean section children; after birth, there are neonatal asphyxia, hypoxia, nuclear jaundice and other medical history.

Cause

1, low birth weight children

Including premature immature children, full-term small samples. These babies have varying degrees of intrauterine growth retardation. At the same time, it also affects the development of the central nervous system, and often complicated by subependymal hemorrhage and intraventricular hemorrhage, the latter is easy to cause spasm on both sides. Easy to cause brain development retardation will not sit.

2. Cerebral hypoxia-ischemia

Therefore, any person who can cause blood circulation and gas exchange barrier between the mother and the fetus, or cause neonatal arterial hypotension, venous congestion, may cause cerebral ischemia and hypoxia, causing brain damage and leaving cerebral palsy. Factors include: maternal factors: such as pregnancy-induced hypertension syndrome, heart failure, major bleeding, anemia, shock or drug use, drug overdose, etc.; placental abnormalities: such as placental abruption, placenta previa, placental infarction or placental dysfunction; Tape blood flow blockage; such as tape prolapse, compression, knotting or around the neck, circulatory failure, polycythemia and so on.

3, nuclear jaundice

It is also an important factor that brain development retardation does not sit, but now due to advances in perinatal medicine, the proportion of cerebral palsy caused by nuclear jaundice has decreased.

Differential diagnosis

Differential diagnosis

The child is very quiet, less crying or hyperactive, crying within 1 to 3 months after birth. 4 months does not respond to the mother, 6 months will not laugh, 12 months will not sit, 18 months will not Walk and speak. Children often open their mouths, stick their tongues, runny, and grind their teeth. They often have unconscious expressions, movements, screams or crying. They have no eyes, they can't consciously look at things, they don't concentrate, they react poorly to things around them, and their language is obviously backward. In the same age, there are sports, vision, and hearing impairment. The head of the child has a small head or a large head or hydrocephalus.
