NEW STUDY UNCOVERS LINK BETWEEN PTSD AND ORAL MICROBIOME IN VETERANS
Summary: The study found a link between the oral microbiome and PTSD in veterans who fought in the 1982 Lebanon War, revealing similar patterns of bacteria in saliva for those with PTSD and high levels of psychopathology. This groundbreaking discovery could lead to new, objective methods for diagnosing PTSD, including post-traumatic stress disorder treatment options. Post-traumatic stress […]
RESEARCHERS DISCOVER BRAIN CIRCUITS CAUSING PHYSICAL RESPONSES TO EMOTIONAL STRESS
Summary: Science has long known that emotional distress causes multiple physical signs due to stimulating the sympathetic nervous system, causing elevated body temperature, pulse rate, and blood pressure. Although these physical responses may be beneficial in the short run, helping initiate a fight or flight response. Still, they cause much harm in the long run, […]
PTSD Symptoms And The Hippocampus: Severity Is Linked To Decreased Hippocampal Activity
Summary: Quite like in other mental health disorders, the diagnosis of PTSD is mainly clinical, and there is no reliable objective test to evaluate disease severity. In a new study, researchers used fMRI brain scans of those who have PTSD. They found that the hippocampal activity of those who have PTSD is subdued. These findings […]
LONG-TERM MOLECULAR CHANGES IN THE BRAIN EXPLAIN SUSCEPTIBILITY OR RESILIENCE TO A TRAUMATIC EVENT
PTSD is a chronic mental health disorder. However, science still does not understand why some people are susceptible to the condition. Understanding why some develop PTSD when exposed to stress and others remain resilient may help develop better treatments. In the new study in mice, researchers found that mice susceptible to PTSD seem to have […]
PTSD, ALONG WITH COMORBIDITIES LIKE SUBSTANCE ABUSE ASSOCIATED WITH CELLULAR MARKERS OF PREMATURE DEATH
Physical ailments increase the risk of premature death. Now studies confirm that PTSD or other mental health issues are also associated with early death. In recent years researchers have developed a reliable biomarker called the “GrimAge” marker. It is a genetic biomarker that can predict the risk of early death. A new study in those […]
