Abstract Background Posttraumatic stress disorder (PTSD) affects approximately 8% of the US population, with varying susceptibility among individuals exposed to trauma. While genetic factors contribute PTSD risk, emerging evidence suggests that epigenetic mechanisms play a crucial role in translating environmental exposures into lasting neurobiological changes. Purpose This review provides comprehensive analysis cutting-edge research on PTSD, particular emphasis novel findings regarding resilience and mechanisms. We explore recent technological advances their applications understanding pathophysiology. Main body Advanced epigenomic approaches have revealed complex interactions between DNA methylation, histone modifications, non-coding RNAs PTSD. Novel highlight cell type-specific signatures temporal dynamics following trauma exposure. Single-cell studies identified previously unknown cellular heterogeneity responses. Recent data modifications not only influence individual but may also transgenerational transmission effects. Integrative multi-omics new insights molecular networks underlying vulnerability. Conclusion unprecedented complexity These open avenues for personalized interventions based profiles suggest therapeutic strategies targeting modifications. enhanced has significant implications risk assessment, prevention, treatment.
