How Do Doctors Test for ADD?

Types

There are three subtypes of ADD--Predominantly Hyperactive/Impulsive, Predominantly Inattentive and Combined Hyperactive/Impulsive and Inattentive. There are different categories that symptoms can fall under that would determine the subtype that a person is experiencing. Predominantly Hyperactive/Impulsive would include six or more symptoms from the hyperactivity/impulsivity categories with less than six in the inattention category. Predominantly Inattentive would include six symptoms from the inattention category with less than six in the hyperactivity/impulsivity category. Combined Hyperactive/Impulsive and Inattentive would include a six or more symptoms from both categories.

Tests for Children

Someone trained in ADD testing must be able to make the diagnosis, such as a psychiatrist, psychologist, behavioral neurologist or social worker. She will go through a checklist and a thorough medical history to rule out other causes of similar symptoms. She will also provide behavioral rating scales for a teacher or caregiver to fill out after observing the child, to determine the severity of impairment. There are also tests to determine if there is a co-existing learning disability, as they are common with ADD. Neurological testing as well as IQ testing may also be done.

Tests for Adults

Some people do not realize they have ADD until they are adults. You will go through similar check lists and attention span tests. You will be asked about different aspects of your life, such as organizational skills, ability to finish tasks, problems with keeping up with bill payments, problems holding a job or frequent career changes and other similar situations. There are no tests for someone to fill out who observes your behavior, but you are better equipped to determine how negatively symptoms are affecting you.

Diagnostic Criteria

Both children and adults must demonstrate multiple symptoms of hyperactivity, impulsiveness or inattention. The symptoms must be severe enough to impact more than one aspect of a person's life, including a person's education, social life, career or interpersonal relationships. The symptoms must have started before the age of seven (for children) and have continued for at least six months. Some other conditions that can cause similar symptoms are usually ruled first and can include lead exposure, anemia, thyroid conditions and seizures.
