ADHD is classified into three subtypes: Predominantly Inattentive Type, Predominantly Hyperactive-Impulsive Type, and Combined Type.

  1. The Predominantly Inattentive Type is marked by significant issues with attention and organisation but less prominent hyperactivity and impulsivity.
  2. The Predominantly Hyperactive-Impulsive Type displays pronounced hyperactivity and impulsivity, with fewer inattention symptoms.
  3. The Combined Type exhibits a combination of inattention, hyperactivity, and impulsivity symptoms.
