A diagnosis of ADHD requires the presence of symptoms:

A diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) is based on the presence of symptoms that must be evident before the age of 12. This timeframe aligns with the criteria set forth in the diagnostic guidelines used by mental health professionals. Early identification is crucial, as ADHD is a developmental disorder that affects a child’s ability to focus, control impulses, and regulate their activity level.

Symptoms typically manifest in early childhood, often becoming noticeable in preschool or early elementary school, which is why the age of 12 is significant. By establishing this cut-off, the diagnostic criteria ensure that the symptoms are recognized and documented in a timely manner, facilitating appropriate interventions and support strategies. This age limit helps in differentiating ADHD from other conditions that may emerge later in life and provides a clear framework for understanding the disorder within the context of child development.
