TB Drugs Treat Parkinson's

The cause of Parkinson's is still a mystery but recent studies may be narrowing the cause to few candidates.  Some researcher felt it possible that Parkinson's was caused by a TB-like bacteria.  The reason its hard to verify this is that TB-like bacteria do not grow  out in culture.  However, some researchers have known that certain TB drugs improve symptoms if not cure it.  

More recently, another mechanism for Parkinson's has come up associated with chronic Manganese poisoning.   

Well it so happens there may be an interesting treatment that covers both bases. An aspirin-like drug called sodium para-aminosalicylic acid used to treat TB also is believed to cross the blood brain barrier and chelate with excess manganese in the brain.

I am interested in following this more closely as research narrows in on a possible cure for this terrible and debilitating disease.  I have heard of other TB drugs being effective for Parkinson's as well.
