Professor Ruth Feldman’s groundbreaking research at Reichman University sheds light on a potential link between gut bacteria and the development of post-traumatic stress disorder (PTSD). Her study focused on Israeli children living near the Gaza Strip and exposed to traumatic events like the 2008 Hamas massacre and explores the fascinating connection between our gut microbiome and mental health.
The study suggests that similarities in gut bacteria between mothers and children may play a role in a child’s susceptibility to PTSD.
The research team aimed to identify a distinct “microbial signature” of PTSD in mothers and their children. Their findings offer promise for developing new therapies that target the gut microbiome to potentially prevent or treat PTSD.

The human gut microbiome is a complex ecosystem teeming with trillions of microorganisms, including bacteria, archaea, fungi, and viruses. These aren’t harmful pathogens, but rather a diverse community playing a vital role in our overall health and well-being.
Gut bacteria assist with digestion by breaking down complex carbohydrates and dietary fibers, allowing our bodies to absorb essential nutrients. They also play a crucial role in our immune system function, helping to differentiate between harmless substances and potential threats. Additionally, these microorganisms produce neurotransmitters like serotonin, influencing mood, sleep, and cognitive function.
The gut and brain are intricately connected through a network known as the gut-brain axis. This bidirectional communication pathway highlights how the health of our gut microbiome can impact our mental well-being.
Professor Feldman’s research suggests that a less diverse gut microbiome may be associated with an increased susceptibility to PTSD in children exposed to trauma. The study followed children and their mothers, measuring PTSD diagnoses and analyzing their gut microbiome composition throughout childhood and adolescence. Interestingly, researchers found that children who developed PTSD had a significantly less diverse gut microbiome compared to resilient children, even though both groups faced similar traumatic experiences.
Feldman’s study included transplanting a PTSD-corrupted microbiome in healthy mice to prove the connection between the microbiome and post-traumatic symptoms. Following the transplant, the mice showed anxious behavior, characteristic of PTSD. Feldman’s “multigenerational, longitudinal, cross-species study embedded within a unique context of chronic trauma marks the first integrative attempt to describe the gut microbiome’s role in the development of PTSD.”
The impact of trauma on a child’s development can be profound. Take Tomer, for instance. Researchers tracked him from age two to seventeen. Initially a sensitive baby – prone to tears, constant nighttime crying, and difficulty calming down – he developed anxieties around new foods and physical touch. This relatively calm child transformed into a toddler plagued by frequent anger outbursts. Even more concerning, he regressed in previously acquired skills, starting to wet the bed again and reverting to single words during playtime, which devolved into simply throwing objects. Understanding the potential role of the gut microbiome in such cases opens doors for new therapeutic approaches.
Professor Feldman’s research paves the way for innovative approaches to diagnosing and potentially preventing PTSD. The ability to identify children with a less diverse gut microbiome following trauma could allow for early intervention and support. This could be particularly beneficial in regions with high rates of chronic trauma, allowing for targeted resource allocation and preventative measures. Furthermore, the research holds promise for the development of microbiome-based therapies. Imagine a future where personalized interventions, potentially including dietary modifications or probiotics, could help individuals cope with trauma and build resilience.
Professor Feldman’s groundbreaking work is a testament to the power of interdisciplinary research. Her “multigenerational, longitudinal, cross-species study embedded within a unique context of chronic trauma” marks a significant step forward in our understanding of the gut-brain connection in the context of PTSD.
Further research is needed to explore the mechanisms by which gut bacteria might influence PTSD development. Collaboration between gastroenterologists, neuroscientists, mental health professionals, and nutritionists will be crucial in developing new diagnostic tools and treatment strategies.
