At What Age Is Hyperactive-Impulsive ADHD Typically Diagnosed? 

ADHD can be diagnosed at different stages of life, but certain subtypes tend to be identified earlier. Hyperactive-impulsive ADHD often shows clear behavioural signs during early childhood. These signs, such as excessive movement, interrupting, or difficulty sitting still, can raise concerns even before a child starts school. 

Typical Diagnosis Age for Hyperactive-Impulsive ADHD 

The average ADHD diagnosis age for the hyperactive-impulsive type is between 4 and 7 years old. This is largely because the symptoms are overt and disruptive in structured settings, such as nurseries or classrooms. 

Behaviours like fidgeting, constant motion, talking excessively, or acting without thinking are difficult to overlook. These early signs lead many families to seek an ADHD diagnosis during the first few years of school or even in preschool. 

This makes hyperactive-impulsive ADHD easier to spot and diagnose at a younger age than the inattentive type, which is often harder to notice. 

How Early Signs Appear Differently in Boys and Girls 

While both boys and girls can show signs of hyperactive-impulsive ADHD, boys are typically diagnosed earlier. They are more likely to exhibit physical hyperactivity, running, climbing, shouting, which attracts adult attention. 

Girls may also have the hyperactive-impulsive type, but their symptoms are sometimes mislabelled as emotional sensitivity or talkativeness. As a result, the age of diagnosis for hyperactive-impulsive ADHD may be delayed in girls. This disparity underscores the need to understand how gender can shape symptom recognition.
