Gut-brain axis: how the microbiome influences anxiety and depression
these data suggest that adolescence is a critical period where the gut-brain axis influences adult anxiety-like behavior. Reproduced, with permission, from [4] (a) and [2] (b). The use of broad-spectrum antibiotics in drinking water has been reported to reduce substantially the microbial number and diversity in healthy adult C57Bl/6 [48].
Gut microbiota’s effect on mental health: The gut-brain axis
Hyperactivity or dysregulation of the HPA axis is one of the most reliable biological readouts in major depression and anxiety. 39 Rats with activated stress circuits demonstrated anxiety and depressive-like behaviors. Removal of the stimulus normalized HPA hyper-reactivity, as measured by their endogenous corticosterone.Source

The brain-gut-microbiota axis is regulated by several mechanisms, including the hypothalamic-pituitary-adrenal (HPA) axis. 55 The hypothalamus releases corticotropin-releasing hormone (CRH) in a humoral manner in response to stress.55 CRH then travels through the bloodstream to the…
About 4% of people in the world live with an anxiety disorder. Current medications used to treat anxiety do not work for everyone. A new study has identified a specific microbial metabolite in the gut microbiome that helps regulate brain activity linked to anxiety, via a mouse model. Researchers believe this finding may one day lead to new anxiety therapies targeting the gut-brain axis.
However, not all people with anxiety respond well to the treatments currently available. Past studies have shown that only 60% to 85%%20(6).) of people treated for anxiety will respond to current treatments.
“It’s vital that researchers continue to find new ways to treat anxiety because current treatments, such as…

In a groundbreaking study, researchers from Duke-NUS Medical School in Singapore have uncovered a potential link between the gut microbiome and anxiety. The findings, which were published in a respected database from the National Institutes of Health, suggest that the absence of gut microbes can lead to increased anxiety levels in mice.
Germ-Free Mice and Behavioral Testing
For this study, the team used a model of germ-free C57BL/6 mice, which have had their gut microbiomes removed. The mice underwent behavioral testing to assess their emotional responses, especially anxiety. According to H.Shawn Le,PhD,an associate professor in the Signature Research Program in Neuroscience and Behavioral Disorders at Duke-NUS Medical School,the team was surprised to find that the germ-free mice exhibited increased anxiety.
The Role of the Basolateral amygdala
The scientists discovered that the heightened anxiety was linked to increased activity in a specific area of the brain known as the basolateral amygdala. This region of the brain plays a crucial role in controlling emotions, especially fear and anxiety. As Le explained, “The basolateral amygdala is a part of the brain that helps control how we feel emotions, especially fear and anxiety. It is a subregion in the amygdala that acts like the brain’s alarm system.”
Exploring New Anxiety Therapies
The researchers later attempted to treat the germ-free mouse model with microbial metabolites called benzodiazepines and SSRIs (selective serotonin reuptake inhibitors). These treatments are commonly used to manage anxiety but come with significant challenges. Le noted, “These drugs can take a long time to show results, and their long-term use is associated with various side effects.”
He further elaborated on the drawbacks of these medications: “For example, benzodiazepines can lead to dependence, sedation, cognitive impairment, and memory problems, while SSRIs are generally safer but can cause problems such as weight gain, sexual dysfunction, or gastrointestinal problems. In addition, individuals may develop an addiction to SSRIs or experience discontinuation symptoms when stopping the medication. Because of these drawbacks, it’s important to explore safer, more effective alternatives to treat anxiety that are backed by solid scientific evidence to improve patient outcomes and reduce the risk of long-term side effects.”
The Gut-Brain Axis
Researchers believe this finding may one day lead to new anxiety therapies targeting the gut-brain axis. This connection between the gut and the brain has gained significant attention in recent years, with studies suggesting that gut microbes can influence mood and behavior.

Stay tuned for more updates on groundbreaking research in the field of mental health and neuroscience.Dr.Ashkan Farhadi’s Outlook:
MNT: What are your thoughts on the gut-brain connection and its implications for anxiety disorders?
Dr. Farhadi: The gut-brain connection is a interesting and rapidly evolving field of research. The idea that our gut microbiota can influence our brain function and behavior, including anxiety, is intriguing.This bidirectional communication between the gut and brain, frequently enough referred to as the “gut-brain axis,” involves complex pathways, including neural, hormonal, and immune mechanisms.
MNT: How does this research impact the way we approach anxiety disorders?
Dr. Farhadi: This research opens up new avenues for developing alternative or complementary treatments for anxiety disorders. If we can modulate the gut microbiota through dietary interventions, probiotics, or prebiotics, we might be able to reduce anxiety symptoms. This could be particularly beneficial for patients who do not respond well to conventional treatments or prefer non-pharmacological approaches.
MNT: What kind of dietary interventions might be effective?
Dr. Farhadi: Dietary interventions that promote a healthy gut microbiota are likely to be beneficial. This includes consuming a diverse range of fruits, vegetables, whole grains, and fermented foods, which are rich in prebiotics and probiotics. Specific probiotic strains, such as Lactobacillus and Bifidobacterium, have shown promise in reducing anxiety symptoms in some studies. Though, more research is needed to identify the most effective strains and dosages.MNT: Are there any potential limitations or challenges in this approach?
Dr. Farhadi: While the potential benefits are exciting, there are also challenges and limitations. The gut microbiota is highly individual, influenced by factors such as genetics, environment, and lifestyle. Therefore, a one-size-fits-all approach may not be effective. Personalized dietary interventions tailored to an individual’s gut microbiota profile may be necessary to achieve optimal results.Additionally, more research is needed to fully understand the mechanisms underlying the gut-brain connection and to develop targeted interventions. Clinical trials are necessary to validate the efficacy and safety of dietary interventions for anxiety disorders.
MNT: Thank you,dr. Farhadi, for sharing your insights on this important topic.
Dr. Farhadi: You’re welcome. It’s an exciting time in the field of gut-brain research, and I look forward to seeing how these findings translate into clinical practice.
Unraveling the Gut-Brain Connection: New Insights into Anxiety and Depression
In the ever-evolving landscape of mental health research, a fascinating new frontier is emerging: the gut-brain-microbiome axis. This intricate relationship between our brain, gut, and the microorganisms residing in our digestive system is shedding light on innovative treatment approaches for conditions like anxiety and depression.
Recent studies have highlighted the bidirectional communication between the gut and the brain. As dr. Emeran Farhadi, a prominent figure in this field, explained, ”Now we know that whatever happens in the brain, changes the gut, and changing the gut changes the microbiome. And vice versa—changing the microbiome changes the gut, and that changes the brain.” This interconnectedness underscores the potential of gut health interventions as a viable strategy for managing mental health disorders [1[1[1[1].
Farhadi emphasized the importance of exploring natural therapies, such as dietary changes, to treat anxiety and depression. “We should have that in mind—medication is a short-term remedy for a long-term problem,” he noted. “And something like diet or altering the diet or lifestyle change that can change the microbiome in the gut is very critical.”
One promising avenue is the use of probiotics, which are live microorganisms that can confer health benefits when consumed. ”At least, I can say, for cases that have a mild anxiety or mild problem with depression, that’s definitely a viable option to try something like a probiotic,” Farhadi added. “What’s the harm of it? None.What’s the benefit? It may benefit them,it may not,but definitely worth a try,or working with some diet that improves the gut health and microbiome.”
