How does the DSM-5 define hyperactivity in ADHD? 

The DSM-5 ADHD criteria provide the official framework for diagnosing attention deficit hyperactivity disorder. Its detailed hyperactivity definition helps clinicians distinguish between everyday high energy and clinically significant symptoms. By using standardised diagnostic criteria, the DSM-5 ensures consistency and accuracy across evaluations. 

According to the DSM-5, hyperactivity involves more than just being active. It refers to persistent, developmentally inappropriate levels of movement and restlessness that interfere with functioning in at least two settings, such as home and school, or work. This ensures that the diagnosis reflects a pervasive and impairing pattern rather than situational behaviour. 

Key DSM-5 Hyperactivity Criteria 

Below are some specific indicators outlined in the DSM-5 ADHD guidelines, along with ways they can be managed: 

Fidgeting or Squirming 

The person is often unable to stay seated and displays constant movement. Behavioural strategies and CBT can help improve self-control and tolerance for stillness. 

Leaving Seat Inappropriately 

Getting up when expected to remain seated, such as during lessons or meetings. Classroom or workplace accommodations, combined with medication, can reduce this behaviour. 

Running or Climbing Excessively 

In children, this often manifests as inappropriate physical activity; in adults, it may feel like inner restlessness. Mindfulness practices and exercise programmes can help use this energy in a positive and productive way.  

By applying these standard diagnostic criteria, clinicians can provide targeted support and reduce the impact of symptoms. Visit providers like ADHD Certify for personal consultations and guidance.
