What causes ADHD in children?

What causes ADHD in children? What are the causes of ADHD? Experts: there are many reasons for children suffering from ADHD, some are congenital reasons, some are acquired human reasons. For the congenital causes of ADHD, we may have more than enough heart and less power, but the acquired causes can be avoided as long as we parents pay a little attention to them. Next, experts will give you a detailed introduction of the causes of ADHD?

1. Acquired causes - organic damage of brain tissue: about 85% of children are caused by frontal lobe or caudate nucleus dysfunction, including: (1) maternal diseases during pregnancy: hypertension, nephritis, anemia, low fever, threatened abortion, cold, etc( 2) Abnormal delivery process: premature delivery, forceps delivery, caesarean section, asphyxia, intracranial hemorrhage, etc( 3) Within 1-2 years after birth, children with central nervous system infection and trauma are more likely to develop ADHD.

2. Congenital reason - lack of brain neurotransmitters: some people think that the occurrence of ADHD may be due to the lack of brain neurotransmitters, which can not be transmitted in time.

Brain neurotransmitter (such as norepinephrine, dopamine) concentration is reduced, can reduce the inhibitory activity of the central nervous system, so that children's action increased. The chemical structure of drugs for ADHD is similar to norepinephrine. After taking drugs, the content of norepinephrine can be increased through various ways to reduce the movement of children. Therefore, ADHD children must be treated with drugs.

3. Congenital causes hereditary factors: about 40% of the parents of ADHD children, their siblings and other relatives, also suffered from this disease in their childhood. Incidence rate of hyperactivity disorder in monozygotic twins is significantly higher than that in twins. All the above points suggest that genetic factors are closely related to ADHD.

4. Postnatal reasons - other factors: in recent years, many parents of only child are eager for their children to grow up. Due to improper educational methods and excessive early intellectual development, the pressure of the external environment far exceeds their children's ability, which is one of the causes of children's hyperactivity disorder (ADHD). In addition, eating artificial dyes in food and excessive intake of lead (not necessarily lead poisoning) can also lead to hyperactivity.
