The discovery of the cause of Alzheimer’s

Alzheimer’s disease is a chronic neuro-degenerative disease that is the cause behind the majority of senile dementia, a disease that affects the patient's ability to remember, think and many other issues. With a strong genetic link previously thought to be the underlying cause for the majority of Alzheimer’s patients, a recent small study has indicated a strong link between long term gum disease and Alzheimer’s, finding gingivitis bacteria present only in the brains of those with Alzheimer’s. It’s thought that the bacteria move first into the blood stream and then into the brain across the blood-brain barrier, causing a series of event that leads to Alzheimer’s; there is at least an association, and at most there is a clear link.
