What is ADHD?

ADHD can reasonably be defined as a behavioral condition that affects attention, hyperactivity, or impulsivity. It should, however, be noted that ADHD exists on a broad spectrum of severity. It is also essential to distinguish between the definition, diagnostic criteria outlined by the DSM-V, and diagnostic standards used by practitioners.

The above chart outlines some of the most common symptoms of ADHD across all ages and those specific to older children and adolescents. It must be emphasized that while many of us can relate to portions of this list of symptoms, that does not mean we all have ADHD. The number, frequency, severity, and persistence of symptoms is what determines if the threshold is met for a diagnosis of ADHD. Most critically, the symptoms must reach a level that interferes with daily functioning. This may take the form of a bright child not passing their classes because they never turn in homework, or a talented athlete being benched because they are distracted by the crowd and lose sight of the ball. Prompt and accurate diagnosis is the first step in preventing this loss of potential.
