Attention deficit hyperactivity disorder (ADHD), commonly known as ADHD, occurs in childhood.

Compared with children of the same age, a group of syndromes characterized by obvious difficulty in concentration, short attention duration, hyperactivity or impulsiveness.

At present, it is generally believed that ADHD is caused by abnormal dopamine secretion in the brain, but the mechanism is unknown. At the same time, it is found that most ADHD patients have dysrhythmia, but the regulation mechanism of biological clock on ADHD is still unclear. This will not only affect their study and life, but also bring a heavy burden to their families, schools and society.

Causes of ADHD in preschool children;

1, genetic factors: preschool children with ADHD have obvious family aggregation. Some scholars believe that the disease is a polygenic hereditary disease, which may be caused by ADHD of parents and other family members, and usually cannot be fundamentally solved.

2. Environmental factors: It is usually because mothers smoke and drink alcohol during pregnancy, which can increase the probability of ADHD in preschool children. If preschool children are exposed to too much environment after birth, it will also cause ADHD in preschool children.

3. Anatomical and physiological abnormalities of the brain: If the frontal lobe of the brain develops abnormally, it may lead to low brain function in areas related to attention and exercise, and may also lead to ADHD in preschool children.

4. Nervous system abnormality: Neurotransmitters such as dopamine in the nervous system may be the main factors to activate the cerebral cortex or strengthen social behavior. If the function of neurotransmitters such as dopamine and norepinephrine in the nervous system decreases, it may also cause ADHD in preschool children.
