What age must symptoms of ADHD be present before for a diagnosis?

The requirement for symptoms of ADHD to be present before a specific age is based on established diagnostic criteria. For a diagnosis of ADHD, the symptoms must manifest prior to age 12. This guideline is rooted in the understanding of the developmental patterns of attention and hyperactivity, with early identification being crucial for effective intervention. Recognizing the symptoms by this age allows healthcare providers to differentiate ADHD from other potential issues and to provide timely support, which is essential for managing the disorder. Early diagnosis increases the likelihood of successful coping strategies and academic and social integration, making it a critical aspect of ADHD assessment.
