There is no single test to diagnose ADHD, instead, determining whether a child or adolescent has this disorder takes many steps.  Because the symptoms of ADHD can be caused by many other factors, a comprehensive evaluation is necessary to establish the diagnosis of ADHD and to rule out other causes for problematic behavior as well as determine the absence or presence of coexisting conditions.

Our ADHD evaluations are comprehensive and do not center around just a survey or questionnaire that teachers and parents fill out.  Students struggle with attention and focus for a lot of reasons and we want to be sure that we are getting to the root of the problem.  We spend 3-4 hours with each student and look at how they learn and process. We look at all their academic areas to determine if there are any gaps present that may be due to inattention or may be causing inattention. We also spend that time observing the student, watching them work, observing their behaviors.  All students have a certain level of inattention and restlessness, we are looking for behaviors that are outside that normal range.  We talk to the student and ask them why they think they may be struggling. We want to hear, in their own words, what they feel is happening each day both in and outside of school. When appropriate, we have the student complete a survey to learn more about how they view their own behaviors as well as their attitude towards school, themselves, and their relationship with peers and parents.  We also will send surveys to parents and teachers but not surveys that only focus on attention but also look at things like anxiety and depression as these are also things that can cause inattentive behavior.

Once we gather all of this information, we determine if the student meets the criteria required to be diagnosed with an attention deficit. To be diagnosed with ADHD, individuals must have six of the nine characteristics in either or both DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) categories listed below. (Adults must have five of the nine characteristics)

In children and teenagers, the symptoms must be more frequent or severe compared to other children the same age. In adults, the symptoms must affect the ability to function in daily life and persist from childhood.

In addition, the behaviors must create significant difficulty in at least two areas of life, such as home, social settings, school, or work. Symptoms must be present for at least six months.

Criteria for the three primary subtypes are:

ADHD – Predominantly Inattentive Type
