An Overview On Neurobiology Of Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder is a neurological disorder that affects approximately ۸% to ۱۲% of children worldwide. ADHD is a disorder in which the child is hyperactive, inattentive, and has sudden behaviors. This disorder is more common in boys than girls. It may be seen in some hyperactive symptoms and sudden behaviors, which is called ADHD or Attention Deficit Hyperactivity Disorder, or in a group of signs of inattention, which is called ADD or Attention Deficit Disorder. Probably the cause of this disorder is a defect in the development of the nervous system. Affected children have partial defects in the frontal lobe of the brain, which is responsible for attention and concentration and regulation of motor activities. Studies show that a decrease in dopamine is a factor in ADHD. Dopamine is a chemical agent in the brain that helps transmit messages from one nerve to another. This substance also plays a role in creating emotional responses and movements. This article aims to provide an overview of recent findings in the rapidly evolving field of ADHD neurobiology with a focus on novel strategies regarding physiological analyses.
