What is the typical onset criterion for ADHD diagnosis?

• A. Symptoms must be present before age 12 and show impairment in two or more settings.
• B. Symptoms must begin before age 12 and show impairment in two or more settings.
• C. Symptoms begin after age 18.
• D. Symptoms require hospitalization.

Answer: (B)

ADHD is diagnosed when symptoms have been present by age 12 and cause impairment in two or more settings. The early onset requirement (by age 12) ensures the symptoms are developmental and pervasive, not just a temporary issue. The impairment across at least two settings (like home and school) shows the pattern affects multiple areas of life, indicating a pervasive problem rather than a situational one. Wording like “begin” versus “present” is mainly semantic, but the essential idea is the same: onset by age 12 with cross-situational impairment. Onset after 18 or requiring hospitalization would not fit the standard criteria.
