ADHD Subtype

A classification of ADHD based on the predominant symptom pattern experienced by an individual. The three recognized subtypes are: predominantly inattentive (difficulty sustaining attention, following through on tasks, and organizing activities), predominantly hyperactive-impulsive (excessive fidgeting, difficulty waiting, interrupting others), and combined presentation (significant symptoms of both inattention and hyperactivity-impulsivity). Subtype identification is important for accessibility because different presentations create different workplace challenges and benefit from different accommodations—for example, inattentive individuals may need reduced distractions and structured task lists, while hyperactive-impulsive individuals may benefit from movement breaks and impulse control strategies.
