Mental Health and Substance Use
Mental health and substance use is the family-medicine area concerned with the recognition, classification, and longitudinal care of common psychiatric and addictive conditions as they present in primary care. It groups conditions that primary-care clinicians encounter frequently and often manage over time, situating them within the generalist, whole-person, and continuity-of-care orientation of family medicine.
Definition
Mental health, in the public-health sense reflected by its MeSH descriptor, refers to a state of well-being and successful psychological functioning; in this family-medicine area the term is used as an umbrella for the common mental and substance-use disorders that present in primary care and for the generalist's role in their identification and continuing care.
Scope
The area orients the reader to the family-medicine perspective on psychiatric and substance-use conditions and links to its detailed topics: depression, anxiety disorders (as encountered in primary care), attention-deficit/hyperactivity disorder, and substance use and addiction. It frames how these conditions are defined in standard classifications (DSM-5, ICD-11) and how their burden is measured at the population level, but it is a reference overview rather than a diagnostic or treatment manual.
Sub-topics
Core questions
- Which mental and substance-use conditions present most often in primary care, and how are they recognized in a generalist setting?
- How do standardized classifications (DSM-5, ICD-11) define and organize these conditions?
- How is the population burden of mental and substance-use disorders measured and compared?
Key concepts
- Common mental disorders in primary care
- Biopsychosocial model
- Continuity and whole-person care
- Diagnostic classification (DSM-5, ICD-11)
- Disability-adjusted burden of disease
- Comorbidity of mental and substance-use disorders
Clinical relevance
Mental and substance-use disorders are among the leading contributors to disability worldwide, and a large share of people affected are first seen, and often managed, in primary care rather than in specialist settings. This area describes how family medicine frames these conditions as part of comprehensive, continuing care; it is educational reference material and is not a basis for individual diagnosis or treatment.
Epidemiology
The Global Burden of Disease analyses identify mental disorders as a major cause of years lived with disability across most regions, with depressive and anxiety disorders contributing the largest shares; substance-use disorders add a further substantial burden. Standardized classifications underpin these counts, and the ICD-11 revision updated how several of these conditions are grouped and defined.
Evidence & guidelines
The conditions in this area are defined by the DSM-5 and the ICD-11 classification systems, and their global burden is quantified by the Global Burden of Disease studies. Detailed, condition-specific evidence and guideline references are given in the individual topic entries rather than at the area level.
History
Across the twentieth and twenty-first centuries, psychiatric nosology was progressively standardized through successive editions of the DSM and the WHO's ICD, while the rise of population health metrics such as the disability-adjusted life year brought the burden of mental and substance-use disorders into comparative focus. The ICD-11, adopted by the World Health Assembly, reflects the most recent consolidation of how these conditions are classified.

Frequently asked questions
- Why are mental health and substance use grouped together in family medicine?
- Both are common in primary care, frequently co-occur, and are managed within the same generalist, continuity-of-care framework; grouping them reflects how a family physician encounters and follows these conditions over time.
- Does this area provide treatment guidance?
- No. It is a reference overview that orients the reader to the conditions and to standard classifications; specific clinical evidence is summarized in the individual topic entries, and none of it is intended for individual diagnosis or treatment.
