Clinical Staging Models in Mental Health
Summary
Clinical staging models in mental health provide a systematic framework for characterising the development and progression of psychiatric disorders over time. Borrowing from approaches in oncology and other branches of medicine, these models divide the course of illness into distinct phases, from early, often subthreshold or prodromal states to established and chronic presentations. By recognising patterns of symptom emergence, functional decline and neurobiological change, staging models aim to guide prognosis, optimise timing of interventions and tailor treatment intensity to stage-specific needs. Across mood, anxiety, psychotic and other severe mental disorders, staging frameworks support early detection services, broaden the remit beyond single diagnostic categories and foster a transdiagnostic perspective on shared underlying mechanisms. In clinical practice they inform stepped-care pathways, ensuring that individuals in attenuated or ultra-high-risk states receive focused preventive strategies, while those in later stages are offered comprehensive multimodal interventions. Globally, this paradigm underpins research into developmental trajectories, enriches risk-stratification algorithms and accelerates the translation of neuroimaging, cognitive and molecular markers into stage-appropriate assessment and management tools.

Clinical Staging Models in Mental Health publication trend
The graph below shows the total number of articles in clinical staging models in mental health across all publications each year (not limited to Nature Index journals).
Technical terms
Clinical staging model: A method for classifying psychiatric illness into ordered phases based on symptom severity, duration and functional impact.
Prodrome: Early signs or subthreshold symptoms that precede the onset of a full-blown psychiatric disorder.
Transdiagnostic: Spanning multiple diagnostic categories by focusing on shared risk factors or underlying mechanisms rather than distinct syndromic criteria.
Ultra-high risk mental state: A state characterised by attenuated or brief psychotic symptoms and functional decline, conferring increased likelihood of transition to psychotic disorder.
Attenuated syndrome: Subclinical symptom presentation that does not meet criteria for a formal diagnosis but indicates elevated risk of progression.
Neuropsychological impairment: Deficits in cognitive domains such as memory, attention and executive function that affect daily functioning.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
