Attention Deficit Hyperactivity Disorder (ADHD) is a condition that becomes apparent in some children in the preschool and early school years. It is hard for these children to control their behavior or pay attention. ADHD was first described by Dr. Heinrich Hoffman in 1845.

   The principle characteristics of ADHD are inattention, hyperactivity, and impulsivity. These symptoms appear early in a child’s life. Symptoms of ADHD will appear over the course of many months, often with the symptoms of impulsiveness and hyperactivity preceding those of inattention, which may not emerge for a year or more.

   Hyperactive children always seem to be “on the go” or constantly in motion. They dash around touching or playing with whatever is in sight, or talk incessantly. Sitting still at dinner or during a school lesson or story can be a difficult task. They squirm and fidget in their seats or roam around the room, or they may wiggle their feet, touch everything, or noisily tap their pencil. Hyperactive teenagers or adults may feel internally restless. They often report needing to stay busy and may try to do several things at once.

   Impulsive children seem unable to curb their immediate reactions or think before they act. They will often blurt out inappropriate comments, display their emotions without restraint, and act without regard for the later consequences of their conduct. Their impulsivity may make it hard for them to wait for things they want or to take their turn in games. They may grab a toy from another child or hit when they’re upset. Even as teenagers or adults, they may impulsively choose to do things that have an immediate but small payoff rather than engage in activities that may take more effort yet provide much greater but delayed rewards.

Some signs of hyperactivity-impulsivity are:
• Feeling restless, often fidgeting with hands or feet, or squirming while seated.
• Running, climbing, or leaving a seat in situations where sitting or quiet behavior is expected.
• Blurting out answers before hearing the whole question.
• Having difficulty in waiting in line or taking turns.
  
Inattention
   Children who are inattentive have a hard time keeping their minds on any one thing and may get bored with a task after only a few minutes. If they are doing something they really enjoy, they have no trouble paying attention. But focusing deliberate, conscious attention to organizing and completing a task or learning something new is difficult.

   Homework is particularly hard for these children. They will forget to write down an assignment, or leave it at school. They will forget to bring a book home, or bring the wrong one. The homework, if finally finished, is full of errors and erasures. Homework is often accompanied by frustration for both parent and child.

The DSM-IV-TR gives these signs of inattention:
• Often becoming easily distracted by irrelevant sights and sounds
• Often failing to pay attention to details and making careless mistakes
• Rarely following instructions carefully and completely losing or forgetting things like toys, or pencils, books, and tools needed for a task
• Often skipping from one uncompleted activity to another.

   Children diagnosed with the Predominantly Inattentive Type of ADHD are seldom impulsive or hyperactive, yet they have significant problems paying attention. They appear to be daydreaming, “spacey,” easily confused, slow moving, and lethargic. They may have difficulty in processing information as quickly and accurately as other children.
