Repeat Brain Injury Raises Soldiers’ Suicide Risk
New research suggests military personnel who suffer more than one mild TBI face a significantly higher risk of suicide.
Brain-Imaging Study Links Cannabinoid Receptors to Post-Traumatic Stress Disorder
Researchers discover a connection between the quantity of CB1 cannabinoid receptors in the brain and PTSD.
Protein Synthesis Blocker Could Help Reduce Effects of Traumatic Events
Researchers note reduced fear and stress responses following a mildly traumatic event when rapamycin, a protein synthesis blocker, is administered.
Nearly 1 in 4 Women Newly Diagnosed with Breast Cancer Report PTSD Symptoms
During the first few months after breast cancer diagnosis, 23 percent of women reported symptoms associated with PTSD, a new study reports.
Police and Firefighters in Early Career at Higher Risk for Mental Disorders Following Traumatic Events
Researchers have discovered new protective service workers, such as police officers and fire fighters, who are repeatedly exposed to traumatic events are at greater risk of developing mental health disorders.
Gene Associated with High Anxiety Can Have Protective Effect on the Battlefield
Through a combination of genetic and psychological testing, researchers have identified factors that mitigate against PTSD. In combat, soldiers who avoided threats were more likely to develop PTSD as a result of traumatic experiences, the study found.
Veterans with Mild Traumatic Brain Injury have White Matter Abnormalities
A new study found soldiers returning from Iraq and Afghanistan with mild TBI have measurable abnormalities in white matter when compared to returning veterans who have not experienced TBI. These abnormalities appear to be related to the severity of the injury and are related to cognitive deficits.
Human Brain is Divided on Fear and Panic
A new study provides proof that the amygdala is not the only gatekeeper of fear in the human brain. Other regions, such as the brainstem, diencephalon, or insular cortex, could sense the body’s most primal inner signals of danger when basic survival is threatened.
Stroke Survivors with PTSD More Likely to Avoid Treatment
A new survey of stroke survivors has shown that those with post-traumatic stress disorder (PTSD) are less likely to adhere to treatment regimens that reduce the risk of an additional stroke.
Potential Treatment for Cognitive Effects of Stress-Related Disorders, Including PTSD
Researchers identified a potential medical treatment for cognitive effects of stress-related disorders, including post-traumatic stress disorder (PTSD). The study, conducted in a PTSD mouse model, shows that an experimental drug called S107, one of a new class of small-molecule compounds called Rycals, prevented learning and memory deficits associated with stress-related disorders.
