Parkinson’s disease (PD) is a common neurodegenerative disorder characterized by misfolding of α-synuclein. Clinical manifestations include slowly developing resting tremor, muscle rigidity, bradykinesia and abnormal gait. The pathological mechanisms underlying PD are complex yet to be fully elucidated. studies suggest that the onset gastrointestinal symptoms may precede motor in patients. microbiota-gut-brain axis plays bidirectional communication role between enteric nervous system central system. This brain gut influenced neural, immune endocrine systems related microbiome. A growing body evidence indicates strong link dysregulation microbiota PD. In this review, we present recent progress understanding relationship We focus on microbiota, unique changes observed microbiome patients, impact these progression Finally, evaluate current treatment strategies for PD, including probiotics, fecal microbial transplants, dietary modifications, drug therapies.

Parkinson's disease (PD) affects more people worldwide than just aging alone can explain. This is likely due to environmental influences, genetic makeup, and changes in daily habits. The develops a complex way, with movement problems caused by Lewy bodies the loss of dopamine-producing neurons. Some research suggests might start gut, hinting at connection between these structures gut health PD patients. These patients often have different bacteria metabolites. Pesticides are known increase risk PD, evidence showing they harm dopamine Long-term exposure pesticides food affect barrier, bacteria, blood-brain but exact link still unknown. review looks how separately influence development progression, highlighting harmful effects bacteria. We examined interaction patients, summarizing cause imbalances resulting changes, their overall on prognosis.
