World Trade Center response crews may face higher heart attack, stroke risk
Post-traumatic stress disorder (PTSD) may increase the risk for stroke and heart attack in both male and female city workers and volunteers who cleaned debris in the aftermath of the World Trade Center plane attack on Sept. 11, 2001. The study sheds light on long-term consequences of PTSD 11-15 years after the event occurred in… Read More »

Adolescents who consume diet high in saturated fats may develop poor stress skills
Adolescents who consume a diet high in saturated fats may develop poor stress coping skills, signs of post-traumatic stress disorder as adults. Read more: Adolescents who consume diet high in saturated fats may develop poor stress skills
Content of service members’ art linked to their trauma levels
A new study found that military service members recovering from PTSD who still identified as a member of a unit have lower levels of psychological injuries. Read more: Content of service members’ art linked to their trauma levels

Psychedelic drugs promote neural plasticity in rats and flies
Psychedelic drugs may have mind-altering powers in the physical sense, too. A new study has found psychedelics, specifically DOI, DMT, and LSD, can change brain cells in rats and flies, making neurons more likely to branch out and connect with one another. The work supports the theory that psychedelics could help to fight depression, anxiety,… Read More »
Physiological benefits may be experienced by veterans with PTSD who use service dogs
A new study shows how veterans with PTSD may benefit physiologically from using service dogs. This study used a physiological marker to define the biobehavioral effects of service dogs on veterans with PTSD.

Immunization with beneficial bacteria makes brain more stress resilient
Rats immunized weekly for three weeks with beneficial bacteria showed increased levels of anti-inflammatory proteins in the brain, more resilience to the physical effects of stress, and less anxiety-like behavior. If replicated in humans, researchers say the findings could lead to novel microbiome-based immunizations for mood disorders like anxiety and PTSD. Read more: Immunization with… Read More »

Scientists show how brain circuit generates anxiety
Neuroscientists have identified a neural circuit in the amygdala, the brain’s seat of emotion processing, that gives rise to anxiety. Their insight has revealed the critical role of a molecule called dynorphin, which could serve as a target for treatment of anxiety-related disorders including post-traumatic stress disorder (PTSD).
