At what age is ADHD typically diagnosed?

ADHD is typically diagnosed prior to age 12, as this aligns with the criteria set forth in diagnostic manuals like the DSM-5. The behavioral symptoms of ADHD, such as inattention, hyperactivity, and impulsivity, usually present themselves in early childhood and can be identified before the child turns 12. Clinicians look for signs of the disorder that are evident across different settings, such as at home and in school, causing impairment in functioning.

Diagnosing ADHD before this age is critical, as early intervention can help improve outcomes for children. While some may argue for earlier diagnostic ages, particularly around age 5, the standard remains that many children do not receive a formal diagnosis until they are older, but certainly before the age of 12, ensuring that the diagnosis is made within the parameters established for effective treatment and support.
