Attention-deficit disorders are marked by persistent patterns of inattention and/or hyperactivity causing disruption to daily life. There are three main types of attention-deficit disorders: inattention, hyperactivity, and impulsivity. A person diagnosed with an attention-deficit disorder is not limited to experiencing symptoms attributed to just one type, a combined diagnosis can occur when symptoms attributed to two or more types occur simultaneously.



There is no single test that can be performed in the diagnosis of an adult-attention deficit disorder. A comprehensive neurological evaluation with in-depth discussions about daily activities, behaviors, and moods is required. During the evaluation assessments are made using specific, standard, guidelines provided by the America Psychiatric Association’s Diagnostic and Statistical Manual.
