Gut brain axis dysfunction: A potential biomarker for early diagnosis of Parkinson disease

Key Points

• Dysfunction of the gut brain axis may serve as a biomarker for early diagnosis of Parkinson disease, indicating a new approach to identification.
• The study highlights significant correlations between gut microbiota changes and early neurological symptoms in Parkinson disease.
• Assessment utilized a comprehensive analysis of gut microbiota composition, emphasizing its relationship with disease onset and progression.
• These findings support the idea that early intervention based on gut health could improve outcomes for patients with Parkinson disease.
