What Are the DSM-5 Criteria for Adult ADHD Diagnosis? 

The adult ADHD criteria outlined in the DSM-5 are used to diagnose ADHD in individuals aged 17 and older. To meet these diagnosis criteria, an adult must display symptoms of inattention and/or hyperactivity-impulsivity that are inconsistent with their developmental level and cause significant impairment in their social, academic, or occupational functioning. 

According to the DSM-5 adult symptoms, a person must exhibit at least five symptoms from either the inattention or hyperactivity-impulsivity categories. For inattention, symptoms may include difficulty staying focused, frequent careless mistakes, or being easily distracted. Hyperactivity-impulsivity symptoms can manifest as restlessness, excessive talking, or impulsive decision-making. These symptoms should be present for at least six months. 

Additionally, the DSM-5 requires that these symptoms must have been present before the age of 12, even if they were not recognised or diagnosed until adulthood. The symptoms must also occur in at least two different settings, such as work, home, or social situations. 

How It Helps 

The adult ADHD criteria in the DSM-5 help ensure that the diagnosis is accurate and comprehensive. By considering both DSM-5 adult symptoms and the diagnosis criteria, healthcare professionals can make a more informed diagnosis. This is crucial for effective treatment plans tailored to adult needs, improving overall well-being and functioning in various aspects of life.
