Abstract
BACKGROUND: The second Think-Tank, sponsored by the Collegium Internationale Neuropsychopharmacologium (CINP), debated the status and prospects of biological markers for psychiatric disorders, focusing on schizophrenia and major depressive disorder. Discussions covered markers defining and predicting specific disorders or domains of dysfunction, as well as predicting and monitoring medication efficacy. Deliberations included clinically useful and viable biomarkers, why suitable markers are not available and the need for tightly-controlled sample collection.
RESULTS: Different types of biomarker, appropriate sensitivity, specificity and broad-based exploitability were discussed. Whilst a number of candidates are in discovery phase, all require replication in larger, real-life cohorts. Clinical cost effectiveness also needs to be established.
CONCLUSIONS: Since a single measure is unlikely to suffice, multi-modal strategies look more promising, although they bring greater technical and implementation complexities. Identifying reproducible, robust biomarkers will probably require pre-competitive consortia to provide the resources needed to identify, validate and develop the relevant clinical tests.
