The evaluation framework
A clinician will combine four streams of evidence: your self-report, structured rating scales, a clinical interview, and (sometimes) collateral or cognitive testing.
Common questions doctors ask
When did you first notice these symptoms? How do they affect work, relationships, and self-care? Have you ever been treated for anxiety, depression, or sleep issues? Family history of ADHD or other mental health conditions? Substance use? Medical conditions like thyroid issues?
The rating scales they use
ASRS-v1.1, CAARS, BAARS-IV, Wender Utah, and sometimes the DIVA-5 (a structured DSM-5 interview). Our homepage test uses the same ASRS questions.
Differential diagnosis
Good clinicians rule out conditions that mimic ADHD: anxiety disorders, depression, PTSD, sleep apnea, hypothyroidism, perimenopause, autism, and bipolar II.
Reaching a diagnosis
DSM-5 requires 5+ symptoms in adults (vs. 6 in kids), present before age 12, in 2+ settings, with clear functional impairment, not better explained by another condition.
