Clinical Topic Updates Podcast: The Evolution of Diagnostic Biomarkers and Neuroimaging in Depression
Despite decades of ongoing research, depression still lacks the widespread availability of reliable biomarkers to help guide diagnosis and treatment. Neuroimaging shows promise but remains impractical due to issues related to cost and access. Pharmacogenomic testing may offer only modest benefit for predicting treatment response, but it may be more useful for determining metabolism and toxicity risk. Inflammatory biomarkers have shown mixed results. As noted in today’s podcast, combining information from multiple types of biomarkers may hold the most promise for helping to predict patient outcomes.
