What are the three types of Attention Deficit Hyperactivity Disorder?

The classification of Attention Deficit Hyperactivity Disorder (ADHD) includes three distinct types, which are predominantly inattentive, predominantly hyperactive-impulsive, and a mixed presentation.

Predominantly inattentive presentation is characterized by symptoms of inattention that may include difficulty sustaining attention, wandering off-task, and not following through on tasks. This type often presents in individuals who may struggle to focus, but may not exhibit hyperactive or impulsive behaviors.

Predominantly hyperactive-impulsive presentation includes behaviors such as excessive fidgeting, talking, interrupting others, and difficulty remaining seated or quiet. This subtype is marked more by hyperactivity and impulsiveness than inattention.

The mixed presentation reflects symptoms of both inattention and hyperactive-impulsive behavior, where individuals display significant difficulties with attention while also exhibiting impulsive actions and hyperactive behavior.

This classification is important for diagnosis and treatment as it helps identify the specific symptoms experienced by the patient and guides effective management strategies. The other choices do not reflect the established nomenclature for ADHD types, which can lead to confusion in understanding the condition.
