Types:
Depending on which symptoms are most prominent in the individual, there are three ways that ADHD manifests itself:
Presentation that is Predominantly Inattentive: It is challenging for the person to arrange or complete a task, to pay attention to details, or to follow directions or dialogues. The individual gets easily sidetracked or overlooks small elements of daily activities.
Presentation that is Predominantly Hyperactive-Impulsive: The person fidgets and talks a lot. Long periods of stillness are challenging (e.g., for a meal or while doing homework). Children that are younger may continually run, jump, or climb. The person is restless and struggles with impulse control. Impulsive persons may speak suddenly, seize objects from others, or interrupt others frequently. The person finds it challenging to follow instructions or wait their turn. Impulsiveness increases the likelihood of accidents and injury for some people.
Combination Presentation: The person exhibits both of the aforementioned types of symptoms in equal measure.
The appearance may alter over time because the symptoms themselves can.
