Rutgers UniversityOct 23 2024 A Rutgers Health study has found that people who took multiple courses of penicillin antibiotics had a modestly lower risk of developing Parkinson's disease, a surprising finding that researchers say highlights the complex relationship between bacteria in the digestive tract and brain health.
"There's an idea that the disease starts in the gut and that inflammation in the gut can make the gut more leaky and allow toxins or inflammation to ascend to the brain through the vagus nerve," Pal said. Related StoriesThe study has limitations, such as its inability to account for other bacteria-affecting behaviors, such as patient diet.
Parkinson's disease affects more than 10 million people worldwide, and cases are expected to rise as populations age. While its exact causes remain unclear, researchers believe a combination of genetic and environmental factors produce the disease. It is primarily diagnosed based on symptoms, as there is no definitive lab test.
