London: New research from King’s College London suggests warning signs for Parkinson’s disease may appear in the mouth and gut. Scientists analyzed spit and stool samples. They compared patients with Parkinson’s and cognitive impairment to healthy volunteers.
Using artificial intelligence, researchers linked specific shifts in oral and gut bacteria to memory and learning problems.
They found higher levels of harmful bacteria in those with mild cognitive impairment and dementia. The team identified bacterial toxins that damage gut tissue and promote inflammation. These toxins could serve as markers for patients at greater risk of dementia.
The study highlights the importance of oral care, a balanced diet, and targeted probiotics. Maintaining microbiome health could slow neurodegenerative processes. Early detection through simple mouth tests may improve the management of Parkinson’s disease.
