    Adverse posttraumatic neuropsychiatric sequelae (APNS) are common among civilian trauma survivors and military veterans. These APNS, as traditionally classified, include posttraumatic stress, postconcussion syndrome, depression, and regional or widespread pain. Traditional classifications have come to hamper scientific progress because they artificially fragment APNS into siloed, syndromic diagnoses unmoored to discrete components of brain functioning and studied in isolation. These limitations in classification and ontology slow the discovery of pathophysiologic mechanisms, biobehavioral markers, risk prediction tools, and preventive/treatment interventions. Progress in overcoming these limitations has been challenging because such progress would require studies that both evaluate a broad spectrum of posttraumatic sequelae (to overcome fragmentation) and also perform in-depth biobehavioral evaluation (to index sequelae to domains of brain function). This article summarizes the methods of the Advancing Understanding of RecOvery afteR traumA (AURORA) Study. AURORA conducts a large-scale (n = 5000 target sample) in-depth assessment of APNS development using a state-of-the-art battery of self-report, neurocognitive, physiologic, digital phenotyping, psychophysical, neuroimaging, and genomic assessments, beginning in the early aftermath of trauma and continuing for 1 year. The goals of AURORA are to achieve improved phenotypes, prediction tools, and understanding of molecular mechanisms to inform the future development and testing of preventive and treatment interventions.

    Brain dynamics reflecting an intra-network brain state is associated with increased posttraumatic stress symptoms in the early aftermath of trauma
    (Research Square, 2024-03-08) Sendi, Mohammad; Fu, Zening; Harnett, Nathaniel; van Rooij, Sanne; Vergara, Victor; Pizzagalli, Diego; Daskalakis, Nikolaos; House, Stacey; Beaudoin, Francesca; An, Xinming; Neylan, Thomas; Clifford, Gari; Jovanovic, Tanja; Linnstaedt, Sarah; Germine, Laura; Bollen, Kenneth; Rauch, Scott; Haran, John; Storrow, Alan; Lewandowski, Christopher; Musey, Paul, Jr.; Hendry, Phyllis; Sheikh, Sophia; Jones, Christopher; Punches, Brittany; Swor, Robert; Gentile, Nina; Murty, Vishnu; Hudak, Lauren; Pascual, Jose; Seamon, Mark; Harris, Erica; Chang, Anna; Pearson, Claire; Peak, David; Merchant, Roland; Domeier, Robert; Rathlev, Niels; O'Neil, Brian; Sergot, Paulina; Sanchez, Leon; Bruce, Steven; Sheridan, John; Harte, Steven; Kessler, Ronald; Koenen, Karestan; McLean, Samuel; Stevens, Jennifer; Calhoun, Vince; Ressler, Kerry; Emergency Medicine, School of Medicine
    This study examines the association between brain dynamic functional network connectivity (dFNC) and current/future posttraumatic stress (PTS) symptom severity, and the impact of sex on this relationship. By analyzing 275 participants' dFNC data obtained ~2 weeks after trauma exposure, we noted that brain dynamics of an inter-network brain state link negatively with current (r=-0.179, pcorrected= 0.021) and future (r=-0.166, pcorrected= 0.029) PTS symptom severity. Also, dynamics of an intra-network brain state correlated with future symptom intensity (r = 0.192, pcorrected = 0.021). We additionally observed that the association between the network dynamics of the inter-network brain state with symptom severity is more pronounced in females (r=-0.244, pcorrected = 0.014). Our findings highlight a potential link between brain network dynamics in the aftermath of trauma with current and future PTSD outcomes, with a stronger protective effect of inter-network brain states against symptom severity in females, underscoring the importance of sex differences.

    Following publication of this article, the authors noticed that the word “not” had been accidentally omitted from the sentence: “A similar pattern is found in the military, where the great majority of APNS cases are found among those who are not severely injured”. This has been corrected in both the PDF and HTML versions of this article.
