ADHD is characterized by the appearance of symptoms before which age?

• A. Before age 7
• B. Before age 12
• C. After age 12
• D. After age 18

Answer: (B)

The key idea is that ADHD is a neurodevelopmental condition whose features must appear during childhood, with a specific cutoff for onset. Diagnostic guidelines require that several symptoms of inattention and/or hyperactivity-impulsivity are present before a certain age (before 12 years old) and that these symptoms cause impairment in more than one setting and persist for a substantial period. This early onset criterion helps distinguish ADHD from conditions that begin later in life and ensures the pattern of symptoms reflects a developmental trajectory rather than a later or situational issue. Even when someone is diagnosed in adulthood, clinicians look for evidence that these symptoms were present before age 12, using reports from parents, teachers, or early records to establish historical onset. So, ADHD is characterized by the appearance of symptoms before age 12.
