Parkinson’s disease is a demyelinating disease, meaning the outer covering of the nerve sheath is being destroyed. Parkinson’s disease is caused by chronic infection, which has invaded the brain; and may be caused by more than one pathogen or combination of pathogens. H-pylori, chlamydia trachoma, and chlamydia pneumonia have all been “associated” with Parkinson’s disease, can invade the brain, and generate abnormally shaped proteins and inclusion cysts.

H-pylori is most strongly “associated” with Parkinson’s disease. H-pylori can migrate to the brain along the vagus nerve, invade through reflux into the sinus, or metastasize through the blood and lymphatics. H-pylori attacks epithelium, can infect and change the shape of neutrophils, and generates abnormal proteins, which look very similar or the same as the “Lewy body” proteins (aggregate of proteins inside the nerve) characteristic of Parkinson’s disease. Stomach ulcers are a common co-morbid condition, and H-pylori is an accepted cause of stomach ulcers.

H-pylori and chlamydia are the primary causes of Parkinson’s disease, alone or in combination.
