German Experts Warn Against Online ADHD Self‑Tests, Stress Need for Professional Diagnosis

Online self‑tests for attention‑deficit/hyperactivity disorder (ADHD) have become popular in Germany, but physicians stress that they cannot replace a structured clinical assessment. Psychiatrist Tobias Hornig warns that self‑diagnoses are attractive because they provide “an identity, belonging to a community and, above all, an explanation: ‘I’m not just lazy or chaotic, my brain works differently.’” However, he cautions that relying on them without professional evaluation can lead to overlooking other conditions and to inappropriate self‑medication.

Both Hornig and senior physician Benedikt Bradtke of the University Hospital Münster describe the diagnostic process as multi‑stage, involving a detailed interview about symptom history, collateral information from relatives or teachers, and standardized questionnaires. They note that self‑tests are often incomplete and that ADHD symptoms can overlap with depression, anxiety, trauma‑related disorders, substance use, sleep deprivation, or other medical issues. A thorough differential diagnosis by qualified psychiatrists, psychotherapists, or psychologists is essential to confirm ADHD and to guide appropriate treatment.
