Combined type ADHD is diagnosed when a person meets DSM-5 symptom criteria for both the inattentive and the hyperactive impulsive presentations. It is the most commonly diagnosed presentation in adults seeking assessment.
People with combined ADHD experience difficulties across attention, organisation, restlessness and impulse control, which can affect work, study, relationships and driving. Identifying the presentation helps tailor both medication choices and practical strategies to the symptoms causing the most impact.
