Explain Sub-categories of ADHD.

Sub-categories of ADHD:
Attention-Deficit/Hyperactivity Disorder (ADHD) has three subtypes:

1. Predominantly Inattentive Presentation: Characterized by difficulties sustaining attention, organizing tasks, and following through on activities, without significant hyperactivity.
2. Predominantly Hyperactive-Impulsive Presentation: Marked by excessive fidgeting, impulsive behaviors, and difficulty remaining seated or quiet, with less prominent inattention.
3. Combined Presentation: Involves a combination of inattentive and hyperactive-impulsive symptoms. These subtypes help tailor interventions to specific challenges individuals face. Accurate diagnosis and understanding of the predominant symptomatology guide effective treatment strategies for individuals with ADHD.
