A 2026 fMRI study of 79 women with interpersonal-violence-related PTSD found that the hippocampus does encode the meaning of autobiographical trauma narratives, t(140) = 4.05, p < 0.001, even though average hippocampal encoding did not rise for trauma vs. neutral memories. Research Highlights Hippocampal semantic encoding was significant: Cisler et al. analyzed 3,928 narrative sentences …
A 2026 multimodal MRI analysis of 509 healthy adults found that fear acquisition, extinction learning, and renewal were not predicted by one generic “fear circuit” score: functional connectivity predicted acquisition, structural connectivity predicted extinction, and effective connectivity was the only renewal signal.1 The extinction result is the clinically interesting piece because exposure therapy depends on …
A 2026 survey of 230 Farsi-speaking refugees in German camps found a hard double signal: 69.1% screened above the RHS-15 threshold for depression, anxiety, and PTSD symptoms, while 4 protective factors explained 61% of posttraumatic-growth variance.1 Research Highlights High distress and growth coexisted: 159 of 230 participants (69.1%) scored ≥12 on the RHS-15 symptom scale, …
Betrayal does not just make people less trusting. It can also change what they pay attention to afterward. After a negative social surprise, people may start scanning more closely for signs of threat, which can make distrust easier to confirm and harder to undo. Research Highlights Selective observation: Son and Yoo 2026 modeled social inference …
Psychedelic-assisted therapy has been one of the most-covered mental-health stories of the past decade. A 2026 quantitative analysis by Evers and colleagues maps how media enthusiasm grew, peaked, and partially pulled back across major U.S. outlets — and how the coverage related to the actual evidence base for depression and PTSD.1 Research Highlights Psychedelic clinical …
The internet era has dramatically changed how people are exposed to traumatic events — uncensored video of violence, war, and disaster reaches civilian audiences within minutes of occurrence. A 2026 study by Allouche-Kam and colleagues examines the mental health consequences of this indirect-trauma exposure in modern populations.1 Research Highlights Indirect trauma exposure through media has …
PTSD and major depressive disorder co-occur in roughly half of patients with either diagnosis, and the comorbid presentation is more severe than either alone. The mechanistic question has been whether comorbidity reflects synergistic biology or simple symptom additivity. A 2026 rat-model study by Jiang and colleagues tests this directly, finding that PTSD-MDD comorbid rats show …
