the term "high-functioning ADHD" is not an official clinical diagnosis or classification within the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th edition) or the ICD-10 (International Classification of Diseases, 10th edition).
ADHD (Attention-deficit/hyperactivity disorder) is typically diagnosed and categorized into three subtypes: predominantly inattentive presentation, predominantly hyperactive-impulsive presentation, and combined presentation. The severity and impact of ADHD symptoms can vary widely among individuals, and some people may appear to function better in certain areas of life despite having ADHD. However, this does not mean that they have a distinct subtype called "high-functioning ADHD."
In clinical practice, the term "high-functioning" is more commonly used in relation to conditions like autism spectrum disorder (ASD). It is essential to avoid using this term when discussing ADHD, as it can lead to misunderstandings and misrepresentations of the condition.
Instead, healthcare professionals and researchers assess ADHD symptoms based on their type, severity, and impairment in various areas of life (e.g., school, work, relationships) to determine the appropriate diagnosis and develop tailored treatment plans. If you or someone you know is experiencing ADHD-related symptoms or concerns, it is advisable to consult a qualified healthcare professional or mental health provider for a proper evaluation and diagnosis.
