Persistent excessive anxiety and worry across multiple areas accompanied by tension and related symptoms.
Reviewed 24 August 2026
Direct answer
Persistent excessive anxiety and worry across multiple areas accompanied by tension and related symptoms. It belongs to the ICD-11 family of anxiety or fear-related disorders. The classification describes a clinically significant pattern, not an identity, moral judgement or explanation for every difficulty a person experiences.
What a qualified professional may explore
The assessment may consider difficulty controlling worry, physical arousal, sleep, duration, function and medical or substance contributors. The clinician also asks how the pattern developed, how it affects ordinary life, which strengths and supports are present, and whether another mental, physical, neurological, developmental, sleep, medicine or substance-related explanation fits better.
Information from family, carers, school or work may be useful only with appropriate consent or another lawful basis. Culture, language, disability and communication needs should be considered explicitly.
Assessment and tests
GAD-7 is a screening aid rather than a diagnostic test. Questionnaires may support screening or track severity, but they do not independently assign an ICD-11 diagnosis. Blood tests, imaging or other investigations are used only where a physical or treatment-safety question justifies them.
When to seek help
Seek a GP or qualified mental-health assessment when the pattern is persistent, worsening, causes substantial distress, restricts daily life or affects relationships, study, work, nutrition, sleep, finances or safety. Earlier support is appropriate when there is rapid change, developmental concern, pregnancy or postpartum onset, substance withdrawal or significant physical symptoms.

Scope, safety and urgent help
iMetaWellness provides complementary wellbeing information and reflective support. It does not diagnose a mental disorder, select investigations, interpret results as a medical opinion, prescribe treatment or replace a GP, psychiatrist, psychologist, pharmacist or NHS service. A test is useful only when a qualified professional has a clear question and a plan for acting on the result.
If someone may act on suicidal thoughts, cannot remain safe, has severe confusion, new psychosis, collapse, seizure, chest pain or another immediate danger, call 999 or attend A&E. For urgent concerns that are not immediately life-threatening, contact NHS 111, the person’s GP, mental-health team or local crisis service.
