According to the results, researchers concluded that a higher level of good bacteria can help reduce inflammation and maintain a balance between flora and mouth. “Our results show the importance of the overall oral microbiome – not only the role of ‘bad’ bacteria but also ‘good’ bacteria – in modulating amyloid levels, ‘ Angela Kamer, PhD, associate professor of periodontology and implant medicine at the NYU College of Dentistry and lead author of the study, said in a statement.
“To our knowledge, this is the first study to show an association between the unbalanced bacterial community found beneath the gums and a CSF biomarker of Alzheimer’s disease in cognitively normal older adults,” Kamer added. “The mouth is home to both harmful bacteria that promote inflammation and healthy, protective bacteria. We have found evidence for brain amyloid associated with increased harmful and reduced beneficial bacteria.” And for more brain health, look if you have this blood type, your risk for dementia is high, study says.
