ADHD is one of the most studied conditions of childhood but the cause of ADHD is still not clear at this time.
The most popular current theory of ADHD is that ADHD represents a disorder of “executive function.” This implies dysfunction in the prefrontal lobes so that the child lacks the ability for behavioral inhibition or self-regulation of such executive functions as nonverbal working memory, speech internalization, affect, emotion, motivation, and arousal.
The symptoms usually are classified as the following types of ADHD: Remember, it is normal for all children to show some of these symptoms from time to time.
Your child may be reacting to stress at school or home.
Another example is a child that may have a learning disability.
He/she may not pay attention in class due to inability to process that information and therefore be labeled with “inattention”.
These conditions can show the same type of symptoms as ADHD.
For example if your child has sleep apnea, a condition that involves disordered breathing during sleep, he may show signs of inattention and inability to focus that can sometimes be similar to a child with ADHD.
Children with attention-deficit/hyperactivity disorder (ADHD) have behavior problems that are so frequent and/or severe that they interfere with their ability to live normal lives.
These children often have trouble getting along with siblings and other children at school, at home, and in other settings.
