PTSD blood test identifies condition with 77% accuracy

There are currently no FDA-approved blood tests for mental health conditions. Post-traumatic stress disorder (PTSD) biomarkers have been identified in the blood samples of veterans with 77% accuracy using an artificial intelligence (AI) tool. The study, led by New York University (NYU) School of Medicine, Harvard John A. Paulson School of Engineering and Applied Sciences, and the U.S. Army Medical Research and Development Command (USAMRDC), analysed 28 genomic, metabolic and protein biomarkers. The biomarkers with the strongest ties to PTSD included the activity levels of certain genes, amounts of key proteins in the blood, levels of metabolites involved in energy processing, and levels of circulating microRNAs. For the study, samples were taken from 83 male, warzone-exposed veterans with confirmed PTSD, and 82 warzone-exposed veterans who did not have the condition.
