Featuring the Work of Dr. Ghazaleh Ghorbannezhad — Neuroscience Research Assistant, Mashhad University of Medical Sciences (MUMS), Iran
Epilepsy remains one of the most challenging neurological disorders worldwide, affecting over 50 million individuals. While modern antiepileptic medications have transformed clinical outcomes, nearly one-third of patients continue to experience drug-resistant seizures, significantly affecting quality of life. This persistent therapeutic gap has fueled a global search for innovative, non-invasive, and accessible treatment strategies.
One of the most groundbreaking directions to emerge in recent years is the exploration of the gut–brain axis—a sophisticated, bidirectional communication system linking the gastrointestinal tract to the central nervous system. Once considered unrelated systems, the gut and brain are now understood to be deeply interconnected through neural, metabolic, hormonal, and immune pathways. Intriguingly, disturbances within the gut microbiome have been shown to influence neuronal excitability, neuroinflammation, and behavioral outcomes, making the gut a powerful therapeutic target for neurological disorders—especially epilepsy.
Among the researchers leading this scientific evolution is Dr. Ghazaleh Ghorbannezhad, MD, a distinguished Neuroscience Research Assistant at Mashhad University of Medical Sciences (MUMS), Iran. With an impressive academic trajectory, numerous awards—including the Best Student Researcher (2023)—and multiple accolades at national and international congresses, Dr. Ghorbannezhad has emerged as a dynamic and influential voice in modern neuroscience. Her work spans neuroimmunology, epilepsy, the gut–brain axis, and novel dietary approaches that complement conventional neurological treatments.
Her latest systematic review, “Gut-Brain Axis Interventions in Epilepsy: A Systematic Review of Diet and Microbiota Modulation,” brings together cutting-edge research, transforming scattered scientific insights into a coherent and actionable framework for future therapies. This blog shines a spotlight on her contributions and explores how gut-focused therapeutics may help reshape the future of epilepsy care.

Beyond her research achievements, she has played significant roles in:
-
delivering scientific workshops,
-
mentoring students,
-
presenting at global conferences, and
-
organizing international scientific events.
Her holistic involvement in academia and scientific outreach strengthens her mission: to bridge fundamental laboratory research with practical clinical applications that can transform patient lives.
The Gut–Brain Axis: A New Frontier in Epilepsy Research
The gut–brain axis is more than a communication pathway—it is a dynamic network involving:
-
the vagus nerve,
-
immune signaling,
-
neuroendocrine pathways,
-
microbial metabolites (such as short-chain fatty acids),
-
neurotransmitter synthesis, and
-
the integrity of the gut barrier.
Disturbances within this system—especially gut dysbiosis, or microbial imbalance—have been linked to increased seizure susceptibility, inflammation, and altered brain metabolism.
Dr. Ghorbannezhad’s systematic review carefully evaluates how modifying the gut environment through diet or microbiota-targeted therapies can significantly influence epilepsy outcomes. Her work highlights both well-established treatments and emerging experimental interventions, offering a comprehensive look at what may become the next generation of epilepsy therapies.
Dietary Therapies: Reshaping Brain Function Through Metabolism
Diet-based treatments are not new in epilepsy, but today’s research reveals the deeper biological pathways that make them effective. Dr. Ghorbannezhad’s review highlights several major dietary strategies:
1. Ketogenic Diet (KD)
Globally recognized as one of the most effective non-pharmacological treatments for drug-resistant epilepsy, the ketogenic diet induces a metabolic shift from glucose to ketone utilization. Its benefits arise from:
-
enhanced mitochondrial function,
-
reduced neuroinflammation,
-
stabilized neuronal firing, and
-
significant changes in gut microbial composition.
Patients on KD often show increased abundance of beneficial bacteria such as Akkermansia and Parabacteroides, which appear to play a critical role in seizure reduction.
2. Modified Atkins Diet (MAD)
A less restrictive but highly effective alternative to KD, the Modified Atkins Diet supports ketosis while offering greater flexibility—improving long-term adherence among both pediatric and adult patients.
3. Low Glycemic Index Therapy (LGIT)
By maintaining stable blood glucose levels, LGIT helps minimize metabolic fluctuations that could impact neuronal excitability. It also promotes healthier microbial diversity compared with more restrictive diets.
4. Anti-Inflammatory & Neuroprotective Diets
Nutrient-rich dietary patterns—including those high in omega-3 fatty acids, antioxidant-rich fruits and vegetables, and polyphenols—may reduce systemic inflammation and support a healthy microbiome, helping maintain optimal brain function.
Microbiota Modulation: A Promising Adjunct in Seizure Management
One of the most exciting aspects of gut–brain axis research is the potential for direct microbial modulation. Dr. Ghorbannezhad’s review identifies several promising interventions:
1. Probiotics
Specific probiotic strains can influence neurotransmitter production, decrease inflammation, and strengthen barrier integrity. Clinical studies show that probiotic therapy can reduce seizure frequency—sometimes by over 50%—making it a compelling adjunct therapy.
2. Prebiotics
These nondigestible fibers nourish beneficial microbes, promoting microbial diversity and supporting neuroprotective metabolic pathways.
3. Synbiotics
Combination formulations of probiotics and prebiotics show synergistic benefits, restoring microbial balance more rapidly and effectively than either therapy alone.
4. Fecal Microbiota Transplantation (FMT)
Although still experimental, FMT has shown dramatic improvements in individual cases of drug-resistant epilepsy, especially where dysbiosis is severe. It offers valuable insights into how profoundly the microbiome can influence brain activity.
5. Antibiotic-Induced Microbial Resetting
Temporary improvement in seizures following certain antibiotic treatments provides additional evidence supporting the microbiome’s influence—but long-term antibiotic use is not a viable therapeutic option.
Neuroimmunology Meets Microbiome Science
A major highlight of Dr. Ghorbannezhad’s research is her emphasis on neuroimmunology—the intersection of immune function and brain health. Dysbiosis can trigger systemic inflammation, which affects:
-
microglial activation,
-
cytokine regulation,
-
blood–brain barrier permeability, and
-
neuronal hyperexcitability.
By targeting the gut, we can indirectly modulate immune pathways that influence seizure susceptibility. This system-level approach strengthens the case for incorporating dietary and microbial therapies into epilepsy care, particularly for patients whose seizures have immune-related triggers.
Why Gut-Based Interventions Are Revolutionizing Epilepsy Care
Gut–brain therapeutics offer several advantages:
-
Non-invasive and safe, with few side effects
-
Cost-effective, especially beneficial in low-resource regions
-
Complementary to antiepileptic drugs
-
Versatile, suitable for children and adults
-
Holistic, improving comorbidities like anxiety, mood disorders, and gastrointestinal issues
This multifaceted impact makes gut-focused therapies an increasingly attractive part of personalized epilepsy management.
The Road Ahead: Precision Medicine and Microbiome Profiling
The future of epilepsy therapy is moving toward precision medicine, and Dr. Ghorbannezhad’s work lays important groundwork for this transition. Scientists are now exploring:
-
microbiome-based biomarkers for predicting treatment response,
-
targeted probiotic formulations personalized to epilepsy subtype,
-
AI-assisted nutritional planning, and
-
integrated neuroimmune–microbiome therapy models.
As research evolves, we may soon see personalized gut-modulation strategies becoming standard components of epilepsy care.
