What is the DSM-5 Criteria for Diagnosing ADHD? 

The DSM-5 ADHD criteria are the standard guidelines used by healthcare professionals to diagnose ADHD. According to the DSM-5 symptoms, a diagnosis of ADHD is made when an individual exhibits a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with daily functioning or development. The symptoms must be present for at least six months and be inconsistent with the individual’s developmental level. 

The DSM-5 ADHD criteria divide the symptoms into two categories: inattention and hyperactivity-impulsivity. To meet the diagnosis, a person must display at least six symptoms from one or both categories, depending on their age. For example, inattention symptoms include difficulties in sustaining attention in tasks or play activities, failure to follow through on instructions, and being easily distracted. Hyperactivity-impulsivity symptoms include fidgeting, difficulty remaining seated, and excessive talking or interrupting others. 

Additionally, the diagnosis guidelines specify that the symptoms must be present in at least two settings (e.g., at home, school, or work), and they must interfere with social, academic, or occupational functioning. The DSM-5 symptoms must also not be better explained by another mental disorder, such as anxiety or depression. 

How It Helps 

The DSM-5 ADHD criteria provide a consistent framework for diagnosing ADHD, ensuring that individuals with the condition receive appropriate treatment. By adhering to these guidelines, healthcare providers can differentiate ADHD from other conditions with similar symptoms, enabling more accurate and effective interventions.
