What is the primary age range for the onset of attention-deficit hyperactivity disorder (ADHD)?

The primary age range for the onset of attention-deficit hyperactivity disorder (ADHD) is typically between 3 to 7 years. During this developmental stage, children undergo significant cognitive and behavioral changes that can reveal symptoms of ADHD, such as inattention, hyperactivity, and impulsivity.

Early identification is crucial as interventions can lead to improved outcomes in academic and social functioning. Behaviors associated with ADHD often become more apparent as children start formal schooling around age 5, where the expectations for focus and self-control increase. Additionally, the DSM-5 criteria for ADHD indicate that symptoms must be present before the age of 12, though many children exhibit signs even earlier.

Understanding these developmental milestones can be vital for parents and educators in recognizing ADHD symptoms, ensuring timely assessment and support for affected children.
