Attention Deficit Disorder and Attention Deficit Hyperactivity Disorder (ADD and ADHD) affect nearly 2 million children in the United States—about 1 child per classroom. Contrary to popular belief, adults are also affected, and at least 3 – 5% of US adults suffer from ADD or ADHD.

ADD vs. ADHD: Symptoms

Though many of the symptoms are similar, ADD and ADHD are two distinct disorders. Both usually develop in early childhood, and can continue through adolescence and adulthood.


Attention Deficit Disorder (ADD) is characterized by poor attention and focus. Children and adults with ADD often:

  • Have trouble paying attention to details
  • Make careless mistakes
  • Do not appear to listen
  • Do not follow directions
  • Have difficulty organizing
  • Avoid tasks that require a sustained mental effort (like homework)
  • Lose things
  • Are easily distracted
  • Forget daily activities (like putting on shoes or taking out the trash)


Attention Deficit Hyperactivity Disorder (ADHD) is characterized by hyperactive behavior and impulsivity. Children and adults with ADHD often:

  • Fidget and squirm all the time
  • Have trouble remaining seated, may run around all the time
  • Have trouble doing quiet activities, like reading
  • Act as if driven by a motor
  • Talk excessively
  • Blurt out answers before the question has been completed
  • Have trouble taking turns or waiting in line
  • Interrupt others
  • Blurt out inappropriate comments
  • Act impulsively (like running out into the street without looking)

Everyone is inattentive, hyperactive, or impulsive at some point in their life. That does not make them ADD or ADHD. People with ADD or ADHD act this way almost all of the time in more than one setting (at home, at school, at work, during activities). These behaviors pervade their daily lives, day in and day out, and can interfere with their schoolwork, jobs, family lives, and relationships.

Children with ADD and ADHD are usually 2 to 4 years behind developmentally, and often appear less responsible and mature than their peers. These problems are often complicated by other conditions, such as anxiety, depression, or learning disabilities, or tactile sensitivity. Over 60% of children with ADD and ADHD have additional conditions, making diagnosing and treating ADD and ADHD difficult. See “Treating ADD and ADHD” or “Is it ADD/ADHD?” for more information.

Causes and Theories

No one knows what causes ADD and ADHD. However, researchers have narrowed down the possibilities, and currently believe that ADD and ADHD stems from biological and chemical changes in the brain, not from the home environment.

Obsolete Theories: Scientists have proposed many theories about the origin of ADD and ADHD through the years; however, none have lasted long. Some of these obsolete theories include:

  • Head Injuries. For some time, scientists thought that ADD and ADHD resulted from minor head injuries or complications during birth. Research has not supported this theory.
  • Sugar. In the early 1980s, researchers believed that sugar, food preservatives, and artificial flavorings caused ADD and ADHD. Today, scientists have found that only about 5% of ADD/ADHD cases are caused by sugar or foods.
  • Too Much TV. Though TV has caused a few rare cases of ADD/ADHD, it is not the culprit in the vast majority of cases. Read more about “TV and the ADD/ADHD Brain”.
  • Poor Home Life. Researchers have found no connections between a poor or dysfunctional home life and ADD/ADHD.
  • Poor Schooling. Researchers have found no connections between the quality of education and ADD/ADHD.

Current Theories: Currently, researchers believe that ADD/ADHD is caused by a complex set of biological and genetic factors. While environmental factors may play a part, no one yet knows when, why, or how.
