You can guarantee that when scientists publish a study titled:
Determining the Presence of Periodontopathic Virulence Factors in Short-Term Postmortem Alzheimer’s Disease Brain Tissue
a newspaper will publish a story titled:
Without access to the paper, it’s difficult to assess the evidence. I suggest you read Jonathan Eisen’s analysis of the abstract. Essentially, it makes two claims:
- that cultured astrocytes (a type of brain cell) can adsorb and internalize lipopolysaccharide (LPS) from Porphyromonas gingivalis, a bacterium found in the mouth
