Associations between white matter microstructural alterations and subclinical posttraumatic stress symptoms in male firefighters

RELATIONSHIPS BETWEEN WHITE MATTER MICROSTRUCTURAL ALTERATIONS AND SUBCLINICAL PTSD SYMPTOMS IN MALE FIREFIGHTERS

Fractional anisotropy values in multiple white matter regions are lower in firefighters than in healthy controls, and posttraumatic stress symptom severity is associated with values in the retrolenticular part of the right internal capsule.

The study aimed to compare white matter connectivity in firefighters exposed to traumatic stressors in the line of duty with that of healthy controls and to examine its association with posttraumatic stress disorder (PTSD) symptom severity. Diffusion tensor imaging data were obtained from 17 firefighters and 27 healthy controls. Fractional anisotropy (FA) was used as an indicator of white matter connectivity, and tract-based spatial statistics and voxel-based statistical analysis were performed. Symptom severity was assessed using the PTSD Checklist for DSM-5 (PCL-5). FA values in firefighters were lower than those in controls, primarily in the internal capsule, external capsule, corona radiata, corticospinal tract, cerebral peduncle, and superior longitudinal fasciculus in the right hemisphere. In the voxel-based correlation analysis, firefighters’ total PCL-5 scores were positively correlated with FA values in the retrolenticular part of the right internal capsule. The authors concluded that posttraumatic stress severity was associated with impaired white matter connectivity. The poster does not report numerical values, p-values, or effect sizes for the between-group differences or the correlation.
