A full assessment and education about attention deficit hyperactivity disorder (ADHD) is the beginning of treatment. ADHD causes suffering: psychological hurt, failure, and conflict with others. The understanding that difficulties with attention were at the heart of some of these difficulties may lead to relief. The title of a popular book You Mean I'm Not Lazy, Crazy or Stupid?! expresses this feeling.

It is not easy to train, discipline, or educate children to control their symptoms of ADHD. Children and adults with ADHD are not always aware of the behaviours that annoy others. Even when insight is present, these symptoms are often involuntary and never processed consciously. Individuals with ADHD know what they should do, and they can do most of these activities. The problem arises with how they actually perform in daily life. Medication improves the symptoms and therefore has an immediate and powerful impact on the impairment that these symptoms produce.

Stimulant medications such as methylphenidate (Biphentin®, Concerta® or Ritalin®), dextroamphetamine (Dexedrine®), amphetamine mixed salts (Adderall XR®) and lisdexamfetamine (Vyvanse®) are commonly used to treat ADHD. These medications vary in how often they need to be taken during the day, as well as in their side effects. Some individuals who do poorly on one stimulant may do better on another. At least 70% of patients will improve on one or another stimulant.

The side effects of stimulants include decreased appetite, stomachaches, insomnia, irritability (especially when the medication is wearing off), and tics. If overmedicated, some children are described as too quiet. There are more than 350 studies that demonstrate unequivocally that these medications are effective for ADHD-combined type in children. There are good studies that also demonstrate that the medication is just as effective for adults.

We have less research to demonstrate that the medication is effective for preschoolers and ADHD-inattentive types. A non-stimulant medication called atomoxetine (Strattera®) has also been shown to be effective. This medication is particularly useful for people who cannot tolerate side effects of stimulant medications and those who have tics or anxiety disorders. The side effects of atomoxetine include upset stomach, decreased appetite, nausea or vomiting, dizziness, tiredness, constipation, and low blood pressure.

It is possible to change the environment to be more ADHD-friendly so that the symptoms of ADHD cause less trouble. For children this might include placement in a specialized classroom, more supervision, increased consequences and rewards, making work more interesting, avoiding difficult situations (such as restaurants or birthday parties), and finding other activities that lead to success, such as skiing or computers. In adults this might mean finding an ADHD-friendly occupation, delegating organizationally challenging tasks and paperwork, and using reminders, sticky notes, cell phones, computers, or other aids. Educating oneself and one's family and friends to understand ADHD helps affirm that the difficult behaviours that go along with ADHD are neither willful, nor personal, nor spiteful.
