Alzheimer’s research has been largely disappointing within the last few decades. There have not been any significant advances in the fight against this insidious disease, which has caused Alzheimer’s to become the fifth biggest cause of death worldwide. Recently, Alzheimer’s researchers have discovered a promising lead with evidence that this disorder may be caused by a bacterium that is involved with gum disease. If this lead proves to be correct, it could lead to better treatment methods and maybe even a vaccine.
During recent studies, it has been discovered that bacteria have been found in the brains of Alzheimer’s patients while they were alive. What is unclear though, is whether the bacteria caused the Alzheimer’s or was able to invade the brains because of the Alzheimer’s. The bacterium in question is called, Porphyromonas gingivalis, and is a known risk factor for Alzheimer’s. This microbe invades the brain, causing inflammation and memory loss. Researchers have found that gum infections in laboratory mice with Alzheimer’s worsens the symptoms. What seems to be the most compelling, is that the gum infection connection is consistent between independent laboratories that are finding similar results.
