Introduction: The Gut-Brain Axis
Scientific evidence increasingly supports what many patients have long suspected: gut health plays a profound role in brain function and mood regulation. This concept, known as the “gut-brain axis,” refers to the bidirectional communication between the gut and the central nervous system. In various neurological conditions, including Parkinson’s disease, multiple sclerosis, and autism spectrum disorders, researchers have observed significant alterations in gut microbiota that appear to influence symptoms.
Gut bacteria produce neurotransmitters such as serotonin, dopamine, and gamma-aminobutyric acid (GABA), all of which are vital for regulating movement, sleep, cognition, and emotional well-being. Moreover, imbalances in the gut can lead to inflammation, increased gut permeability, and even immune dysregulation, which in turn may affect the nervous system.
Dystonia and Gut Dysbiosis
In my clinical practice, I began to observe a pattern: many of my patients with dystonia also reported gastrointestinal (GI) distress. To explore this further, I conducted a study involving 809 patients with different types of dystonia to determine how many also experienced symptoms suggestive of gut dysbiosis.
Study Results: Gastrointestinal Distress Among Dystonia Patients
Dystonia Type | Total Patients | Patients Reporting GI Distress | Percentage with GI Distress |
---|---|---|---|
Cervical Dystonia | 436 | 205 | 47.0% |
Blepharospasm | 145 | 43 | 29.7% |
Oromandibular Dystonia | 86 | 41 | 47.7% |
Hand Dystonia | 61 | 27 | 44.3% |
Leg Dystonia | 43 | 16 | 37.2% |
Spasmodic Dysphonia | 38 | 17 | 44.7% |
These findings suggest a significant overlap between dystonia and symptoms associated with gut dysbiosis. While the intensity of GI symptoms varies from patient to patient, the prevalence warrants deeper exploration.
Gut Microbiome and Neurotransmitters: The Chemical Messengers
Serotonin
About 90% of serotonin is produced in the gut. This neurotransmitter regulates mood, sleep, and bowel movements. Imbalances in gut flora can lead to reduced serotonin levels, contributing to mood disorders, disrupted sleep, and possibly exacerbating dystonia symptoms.
Dopamine
Dopamine plays a key role in motor control, and its dysregulation is linked to movement disorders. Certain gut bacteria, such as Lactobacillus and Bifidobacterium, have been found to influence dopamine production and receptor sensitivity.
Glutamate
This excitatory neurotransmitter is involved in learning and memory but, when unregulated, can cause neurotoxicity. Dysbiosis may contribute to altered glutamate signaling, potentially heightening involuntary movements and motor symptoms.
Inflammation and IBS
Chronic gut inflammation can lead to increased permeability (“leaky gut”), allowing harmful substances to enter the bloodstream and trigger systemic inflammation, including in the brain. This is particularly relevant for individuals with Irritable Bowel Syndrome (IBS), where inflammation and altered gut motility are common.
Abdominophrenic Dyssynergia and Dystonia
In individuals with IBS, a condition called abdominophrenic dyssynergia—where the diaphragm and abdominal muscles contract in opposition—can exacerbate bloating and abdominal distension. I have observed that many of my dystonia patients display signs of this condition, suggesting a link between disrupted diaphragmatic function and both gastrointestinal and neurological symptoms.
Specific Changes in Bacteria Found in Dystonia Patients
Recent scientific literature provides valuable insights into the specific bacterial alterations observed in dystonia patients:
Increased Aerotolerant Species:
-
Blautia obeum has been reported in greater abundance (PMID: 34346706).
Function/Neurotransmitter: Blautia obeum plays a role in short-chain fatty acid (SCFA) production, which can impact gut-brain communication and potentially influence serotonin production. -
Dorea longicatena has been documented more frequently in dystonia patients (PMID: 34346706).
Function/Neurotransmitter: Dorea longicatena is involved in the production of butyrate, which has been linked to neuroinflammation regulation and serotonin synthesis. -
Eubacterium hallii has been found in higher amounts (PMID: 34346706).
Function/Neurotransmitter: Eubacterium hallii contributes to the production of butyrate, a key SCFA that influences the gut-brain axis and can affect dopamine levels. -
Additionally, Ruminococcus torques appears more frequently in dystonia patients (PMC9916458).
Function/Neurotransmitter: Ruminococcus torques is associated with the production of acetate, which is involved in metabolic processes that can influence brain function and neurotransmitter regulation. -
Dorea formicigenerans also appears more frequently in dystonia patients (PMC9916458).
Function/Neurotransmitter: Dorea formicigenerans contributes to the production of butyrate, which has been shown to modulate serotonin levels and support gut-brain communication.
Decreased Beneficial Species:
-
Lower levels of Bacteroides vulgatus have been documented (PMID: 34346706).
Function/Neurotransmitter: Bacteroides vulgatus is involved in the degradation of dietary fibers and the production of SCFAs, including butyrate, which supports serotonin synthesis and gut health. -
Bacteroides plebeius has shown a decrease in dystonia patients (PMID: 34346706).
Function/Neurotransmitter: Bacteroides plebeius aids in the production of SCFAs, particularly acetate and butyrate, which influence neurotransmitter synthesis, including serotonin and dopamine. -
Bacteroides eggerthii has been found at lower levels in dystonia patients (PMID: 34346706).
Function/Neurotransmitter: Bacteroides eggerthii supports the production of butyrate and acetate, which are crucial for modulating brain chemistry, including serotonin levels. -
These reductions may impair tryptophan metabolism, potentially impacting serotonin production and immune modulation.
Practical Recommendations for Managing Dystonia and Gut Health
In managing dystonia, a holistic approach that addresses both the neurological and gut health aspects of the condition is essential. Based on years of clinical experience, I recommend working with a healthcare team to incorporate strategies that support gut health and alleviate symptoms.
As part of my Dystonia Recovery Program, I’ve collaborated with nutritionist and pharmacist Bonnie James to create a comprehensive nutrition class specifically for dystonia patients. This program addresses key issues like gut microbiome dysbiosis and its potential impact on neurological symptoms, offering tailored recommendations, practical solutions, and recipes designed to support overall health and well-being.
Patients in this program receive guidance on managing gut health, improving digestion, reducing inflammation, and incorporating gut-friendly foods that may help alleviate dystonia symptoms. This approach ensures that individuals have access to effective, actionable advice as they navigate their recovery.
Incorporating probiotics, prebiotics, a balanced diet, proper sleep, stress reduction, and collaborating with both your doctor and nutritionist are all crucial steps in managing your condition. I encourage you to explore the Dystonia Recovery Program to gain a more personalized and comprehensive approach to improving your health.
Conclusion: A New Frontier in Dystonia Care
The gut-brain connection is not just theoretical—it is physiological and real. My research and clinical experience strongly indicate that gut health plays a vital role in the expression and management of dystonia. Understanding and addressing dysbiosis may offer a novel, complementary pathway for improving patient outcomes. Future research will help us refine these interventions and explore the full potential of microbiome-focused therapies in the management of dystonia.
