Attention Deficit Hyperactivity Disorder (ADHD)

            Attention deficit hyperactivity disorder (ADHD) is the most common behavior

 disorder diagnosed in children and teens. ADHD refers to a group of symptoms that begin

 in early childhood and can continue into adulthood, causing difficulties at home, at school,

 at work, and within the community if not recognized and treated. I chose this topic

 because now it seems that everyone has this disorder because of tv and the quick and

 meaningless images we are bombarded with by it everyday. I wanted to learn more about

 this topic: the causes, the symptoms, and the treatment.                                               

            The exact cause of attention deficit hyperactivity disorder (ADHD) is not known.

 However, inherited genetic factors are likely responsible. A specific has not been directly

 linked to ADHD, but a relationship is suspected between symptoms and brain structure,

 which influences temperament, the function of chemicals in the brain that help regulate

 attention and activity (dopamine and norepinephrine), abnormal function of the prefrontal

 cortical lobe that causes problems with attention and impulse control, certain enviromental

 factors, such as lead exposure, or having a mother who smoked or drank alcohol during

 pregnancy, may also contribute to the risk of developing ADHD. There is no evidence to

 support claims that ADHD is caused by too much sugar or allergies to specific foods.
