A recent study published in Behavioral Neuroscience offers new insights into the relationship between brain structure and posttraumatic stress disorder (PTSD). The study found that smaller volumes in specific regions of the hippocampus, a brain structure involved in memory and learning, are associated with reduced PTSD symptom severity over time. This counterintuitive finding suggests a complex relationship between hippocampal structure and PTSD symptoms, particularly in how these brain regions may influence symptom improvement. PTSD is a mental health condition that can develop after experien...

Researchers from The Australian National University and the University of Queensland have found evidence that individuals with autism spectrum disorder (ASD) are more prone to developing post-traumatic stress disorder (PTSD). The study, published in iScience00969-6), indicates that even mild stress can trigger traumatic memories in those with autism, exacerbating core traits such as repetitive behavior. The research, conducted on mice, identified specific brain mechanisms underlying this heightened stress sensitivity. Autism spectrum disorder is characterized by difficulties in social interact...

A recent study published in Scientific Reports reveals that art therapy, specifically mask-making, may reflect significant emotional changes in military personnel suffering from post-traumatic stress symptoms. Art has long been recognized as a powerful form of non-verbal communication, capable of expressing complex emotions and experiences which may be challenging to articulate through language. Post-traumatic stress symptoms, including irritability and aggressive behavior, affect a significant number of military service members. While medications such as antidepressants are commonly used to t...

A new study published in Translational Psychiatry reveals that 2.17% of preadolescent children aged 9 to 10 years old in the United States have experienced post-traumatic stress disorder (PTSD) at some point in their lives. Factors including sexual minority status and previous history of PTSD were discovered to increase the risk of the disorder, and alarmingly more than a third of the participants did not receive any mental health treatment. While PTSD has been extensively studied in adults and adolescents, little is known about its prevalence and impact on children aged 9 to 10, with previous...

A new study published in the Journal of Affective Disorders provides preliminary evidence that creatine levels in a specific region of the brain could play a role in recovering from traumatic events. The study, conducted with a small group of United States veterans, suggests that higher levels of creatine are associated with better recovery from stress caused by traumatic experiences. The study was motivated by the critical need to understand why some individuals recover from traumatic events while others develop long-lasting psychological conditions like post-traumatic stress disorder (PTSD)....

On October 1, 2017, a devastating mass shooting at the Route 91 Harvest Music Festival in Las Vegas left 60 people dead and 867 injured. A recent study published in JAMA Network Open has revealed that even four years after this tragic event, a significant number of the survivors and witnesses continue to suffer from severe mental health issues. Specifically, nearly half of the concertgoers surveyed reported experiencing major depressive episodes in the past year, while over 63% faced symptoms of post-traumatic stress disorder (PTSD). Mass violence incidents, like the 2017 Las Vegas shooting, o...

In a pilot study, scientists were able to train dogs to recognize stress cues on the breath of humans who had been reflecting on their past traumatic experiences. Although some assistance dogs can already alert to physical cues of post-traumatic stress disorder (PTSD) symptoms, dogs that can smell early warnings could act to help their companion earlier, before a patient is consciously aware an episode has started – making the intervention more effective. Dogs’ sensitive noses can detect the early warning signs of many potentially dangerous medical situations, like an impending seizure or sudd...

In a recent study, neuroscientists from Scripps Research discovered that targeting specific neurons involved in the brain’s stress response could potentially reduce alcohol consumption in individuals suffering from both post-traumatic stress disorder (PTSD) and alcohol use disorder (AUD). Published in Molecular Psychiatry, this research offers a promising direction for developing new treatment strategies for people grappling with these interlinked disorders. Individuals with PTSD are at a heightened risk of developing AUD, often using alcohol as a coping mechanism to mitigate the symptoms of P...

In an innovative clinical trial, a blend of brain stimulation and virtual reality exposure therapy has shown promising results for U.S. military veterans grappling with post-traumatic stress disorder (PTSD). The study, detailed in a recent publication in JAMA Psychiatry, found a significant easing of PTSD symptoms among participants undergoing this novel treatment approach. PTSD is a condition that severely impacts individuals’ lives, characterized by symptoms such as intrusive thoughts, avoidance behaviors, heightened arousal, and mood disturbances. It’s notably prevalent and debilitating amo...

Among the many emerging trends on social media, one recent concerning fad is a casual and often inaccurate portrayal of trauma and post-traumatic stress disorder, or PTSD – along with an array of questionable interventions suggested for its cure. But what really is PTSD, who suffers from it, and what are the available treatments? As a psychiatrist specializing in trauma, I’ve worked with hundreds of people with PTSD. Some are refugees, first responders and survivors of torture and human trafficking. Others have survived childhood trauma, shootings, assault, rape or robbery. As part of my outre...
