| Summary: | Parkinson’s disease (PD) is a chronic, progressive neurodegenerative disorder characterized by debilitating motor and non-motor symptoms. Its etiology is multifactorial, with no single definitive cause identified, although aging is a significant risk factor. Additional risks include genetic predisposition, family history, and environmental factors such as pesticide exposure and Helicobacter pylori infection. Dysbiosis of the gut microbiota, and in particular bacterial imbalances, has been implicated in the disruption of the gut-brain axis, contributing to both systemic and neuroinflammation. Environmental factors such as antibiotic exposure and toxins can precipitate microbial dysregulation, potentially accelerating PD progression. Understanding the mechanisms of the gut-brain axis and identifying strategies to preserve a healthy microbiome are essential for developing novel therapeutic approaches. This review synthesizes current therapeutic strategies and ongoing research focused on restoring gut-brain balance to combat PD. These approaches include fecal microbiota transplantation, dietary interventions, and probiotic therapies, all of which show promise in mitigating both motor and non-motor symptoms. Furthermore, we emphasize the urgent need for continued research into probiotics and innovative therapeutic approaches for gut-brain axis modulation, presenting novel opportunities for effective PD management. |
