Question
Why do some children develop Attention Deficit Hyperactivity Disorder (ADHD)?
Answer
The causes of ADHD in children may involve a variety of factors, including minor brain injuries, genetic factors, and abnormalities in the secretion of certain neurotransmitters. Research indicates that there is a higher probability for parents of children with ADHD to also have the condition or other psychiatric disorders. The risk of ADHD in monozygotic twins is also higher than that in dizygotic twins. Additionally, certain neuroanatomical features and abnormalities in the transmission of brain signals may be related to ADHD. Environmental factors such as food allergies or food additives may also trigger hyperactivity and attention problems in children. Theories from neuropsychology and neurobiology emphasize the relationship between attention shifting and impulse control and Attention Deficit Hyperactivity Disorder (ADHD).
