Medical disclaimer

The differential screener on notadhd.com is not a diagnostic instrument. It compares your self-reported responses against symptom patterns associated with several conditions and shows you which ones your responses align with most. The output is intended as a conversation starter with a qualified clinician — not a diagnosis.

A clinical diagnosis of any of these conditions — ADHD, generalized anxiety disorder, depression, sleep disorder, autism, PTSD, bipolar disorder — requires a trained clinician taking a full history, considering medical and developmental factors, ruling out other causes, and applying current diagnostic criteria. No online tool can do this.

Always consult a qualified healthcare professional regarding any questions about a medical condition, medication, or symptoms. Decisions about starting, stopping, or changing treatment should be made only with the guidance of a licensed clinician.

In an emergency, do not use this website. Call your local emergency number or go to the nearest emergency department. If you are having thoughts of self-harm, contact a crisis line in your country (in the US: 988; in the UK: Samaritans 116 123).
