Teretxu and reverett123,

Thanks for your responses. I shall try to be on the lookout for multiple causes contributing to Parkinson's. So far I'm thinking - not enough copper and/or too much manganese; inherited weaknesses; fluoride toxicity; Lyme disease.

"Dr. Mattman states 'I’m convinced Lyme disease is transmissible from person to person.' In 1995 Dr. Mattman obtained positive cultures for Bb from 43 of 47 persons with chronic illness. Only 1 of 23 control patients had a positive Bb culture. Dr. Mattman has subsequently recovered Bb spirochetes form 8 out of 8 cases of Parkinson’s Disease, 41 cases of multiple sclerosis, 21 cases of amyotrophic lateral sclerosis and all tested cases of Alzheimer’s Disease."

There is some evidence that one of the Lyme disease bacteria may cause amyloid deposits:

By the way, in case you're interested, the following link discusses the possible connections between Lyme disease and multiple sclerosis:
