It’s difficult for patients to absolutely know if they have Parkinson’s disease. To date, the only way to diagnose someone with Parkinson’s is to do a clinical exam to access his or her symptoms.  And in order to definitively get an answer, an autopsy is performed on the brain – only after the person has died. But now, a conclusive clinical test may soon be available.  Researchers from the Mayo Clinic in Arizona have found that examining a specific portion of a person’s saliva gland may be able to diagnose someone with Parkinson’s.
