What is the most common age for ADHD symptoms to manifest in children?

ADHD symptoms typically manifest between the ages of 4 and 7, with the most commonly reported age being around 6 years old, when children start formal schooling and behavioral expectations increase. This age is crucial as it marks a transition into environments that require sustained attention and impulse control, traits that are often challenging for children with ADHD. While children may exhibit some signs earlier, it is during this period that symptoms become more observable and can impact academic and social performance. Therefore, choosing age 8 as the most common age for the manifestation of symptoms is not aligned with the typical developmental timeline, which highlights the importance of recognizing these symptoms as early as possible to facilitate timely intervention.
