Treating Chronic Infections May Block Alzheimer's and dementia
Amsterdam – Researchers are breaking new ground in the emerging role of infection in the development of Alzheimer's.
A number of chronic diseases are in fact caused by one or more infectious agents. For example, stomach ulcers are caused by Helicobacter pylori, chronic lung disease in newborns and chronic asthma in adults are both caused by Mycoplasmas and Chlamydia pneumonia, while some other pathogens have been associated with atherosclerosis. The realization that pathogens can produce slowly progressive chronic diseases has opened new lines of research into Alzheimer’s disease.
In a special issue of the Journal of Alzheimer’s Disease published May 2008, guest editors Judith Miklossy, from The University of British Columbia, and Ralph N. Martins, from Edith Cowan University and Hollywood Private Hospital, Perth, Western Australia, and a group of experts explore this exciting topic. Alzheimer’s disease (AD), the most frequent cause of dementia, is a form of amyloidosis. It has been known for a century that dementia, brain atrophy and amyloidosis can be caused by chronic bacterial infections, namely by Treponema pallidum in the atrophic form of general paresis in syphilis. Bacteria and viruses are powerful stimulators of inflammation. It was suggested by Alois Alzheimer and his colleagues a century ago that microorganisms may be contributors in the generation of senile plaques in AD.
