How Is ADHD Diagnosed in Adolescents Using DSM-5 Criteria? 

The adolescent ADHD diagnosis follows specific guidelines outlined in the DSM-5. Diagnosing ADHD in adolescents involves identifying a pattern of symptoms related to inattention, hyperactivity, and impulsivity that persist for at least six months. These symptoms must significantly impair the adolescent’s ability to function in at least two settings, such as at school, at home, or in social situations. 

For a DSM-5 adolescent ADHD diagnosis, the symptoms must be more severe than what is typical for their developmental stage. Inattention symptoms in teenagers may include trouble focusing on tasks, disorganisation, or forgetfulness. Hyperactivity might manifest as restlessness or an inability to stay seated, while impulsivity could result in hasty decisions, interrupting others, or engaging in risky behaviours. 

The teenage ADHD diagnosis also requires that symptoms appear before the age of 12, even if they may not have been recognised until adolescence. Moreover, the DSM-5 emphasises that the symptoms should not be better explained by other mental health conditions, such as anxiety or mood disorders. 

How It Helps 

The DSM-5 criteria for adolescent ADHD diagnosis help clinicians identify ADHD in teenagers, which can often be overlooked due to the overlap with typical teenage behaviour. By adhering to these guidelines, healthcare professionals can accurately diagnose ADHD, leading to more effective and age-appropriate treatment strategies that improve the adolescent’s functioning in school, social interactions, and daily life.
