Adult ADHD is becoming an increasingly important part of psychiatric practice, but diagnosing and treating ADHD in adults requires more than identifying problems with focus. The new U.S. Adult ADHD Guidelines are currently in their final review stage, with publication anticipated in fall 2026. For PMHNPs and psychiatric clinicians, this is a good time to revisit the fundamentals. When evaluating an adult for possible ADHD, clinicians should consider: 🧠 Clinical history — Is there evidence of symptoms beginning in childhood, and how have they affected the patient's functioning over time? 🔍 Differential diagnosis — Could anxiety, depression, sleep disorders, substance use, or another condition better explain the symptoms? 📋 Functional impairment — How are symptoms affecting work, relationships, daily responsibilities, and other areas of life? 💊 Treatment options — When should medication be considered, and what factors should guide the choice of treatment? 🤝 Individualized care — How should treatment be adapted based on comorbidities, patient preferences, risks, and clinical response? 📈 Ongoing monitoring — How should clinicians assess treatment response, adverse effects, and changes in functioning over time? The goal isn't simply to recognize ADHD. The goal is to diagnose it accurately, distinguish it from overlapping conditions, and treat the whole patient. 💭 Clinical Question What is the most challenging part of evaluating or treating adult ADHD in your clinical practice?
