Patient's question:
Why do some children have ADHDDoctor's answer:
Biological factors, including minor brain injuries and genetic factors. In children with ADHD, their biological parents are more likely to have ADHD and mental disorders. The incidence of ADHD is higher in monozygotic twins than in dizygotic twins. Some abnormalities in the secretion of brain neurotransmitters, as well as neuroanatomical characteristics, are also related to ADHD. Environmental factors also play a certain role. Some studies suggest that food allergies can cause hyperactivity and attention disorders in children, while others propose that food additives and salicylates can lead to childhood hyperactivity. The hypotheses of neuropsychology and neurobiology emphasize the concept that attention shifting and impulsivity control cause attention deficit disorder.
