Attention Deficit Hyperactivity Disorder (ADHD) in young children, abbreviated as ADHD. It refers to a common behavioral disorder in children who, despite having normal basic conditions, have behavioral and emotional deficiencies and find it difficult to get along with others compared to their peers. So, how is ADHD formed?
The causes of ADHD in children are complex and are related to the following factors.
1. Genetic factors: Studies have shown that ADHD in children is related to genetic factors, often due to polygenic inheritance.
2. Neurophysiological factors: The abnormality rate of EEG in children with ADHD is high, indicating that ADHD has problems with delayed maturation of the central nervous system or insufficient awakening of the cerebral cortex.
3. Mild brain injury: Mild brain injury caused by various reasons during pregnancy and before and after fetal birth is the cause of ADHD in some children. Currently, it is believed that premature birth, low birth weight, hypoxic-ischemic brain injury, meningitis, encephalitis, traumatic brain injury, and thyroid dysfunction are often related to childhood hyperactivity disorder.
4. Central nervous system factors: Studies have shown that ADHD in children is often associated with decreased renewal rates of dopamine and adrenaline, or dysfunction of dopamine and norepinephrine, as well as metabolic disorders in the central nervous system.
5. Other factors: ADHD in children may be related to zinc deficiency, iron deficiency, and elevated blood lead levels, and food additives may also increase the risk of ADHD in children.
