What causes ADHD in children?

The occurrence of ADHD in children may be affected by many factors, including genetic factors. If the mother smokes and drinks heavily during pregnancy, it may also cause this symptom. Vitamin deficiency and food allergies may also be reasons.

1. The mothers of the affected children often have more complications during pregnancy or perinatal period, and often have a history of heavy smoking or alcoholism.

2. Genetic factors, such as: the child's blood brothers, father, etc. have more hyperactivity or inattention; the incidence rate of monozygotic twins is as high as 51% to 64%; there are also many relatives with alcoholism, antisocial personality and hysteria.

3. Although the research results of neurotransmitters and enzymes are often contradictory, it is still a way to study the cause of this disease.

4. Severe lead poisoning can cause fatal toxic encephalopathy, dementia and other neurological damage, but there is no conclusion yet on whether mild lead poisoning can cause ADHD.

5. The influence of social, family and psychological factors, such as bad social environment or family conditions (broken families, economic poverty, crowded housing, parents with bad personalities, alcoholism, drug abuse, mental illness, etc.), can all become triggers of the disease and affect the development of the disease and prognosis.

6. Other factors: Nutritional problems, vitamin deficiency, food allergies, food flavorings or added artificial colors may make children more susceptible to ADHD.
