ADHD refers to attention-deficit/hyperactivity disorder. The development of attention-deficit/hyperactivity disorder mainly involves the following factors:
1. Genetic factors: If one family member has ADHD, other family members may also have a higher risk of developing the disorder.
2. Imbalance of neurochemical substances: Neurotransmitters in the brain, such as dopamine, norepinephrine, and serotonin, play important roles in regulating attention, emotions, and behavior. Patients with ADHD may have abnormal neurotransmitter levels, leading to dysfunction in neural regulation, thus affecting attention and behavioral control.
3. Neurodevelopmental issues: Brain regions such as the prefrontal cortex, amygdala, and striatum may exhibit structural and functional changes in individuals with ADHD. These brain regions are associated with attention and behavioral control.
4. Environmental factors: Maternal smoking, alcohol consumption, infections, poisoning, malnutrition, medication use, and X-ray exposure during pregnancy, as well as brain injury during childbirth, prolonged labor, premature birth, and post-term birth, may all increase the child's risk of developing ADHD.
