According to a preliminary study presented at the 70th American Academy of Neurology annual meeting certain proteins in tears may be useful biomarkers.
Researchers at USC found the levels of total alpha-synuclein to be decreased in patients with Parkinson's disease compared to healthy controls.
But levels of oligomeric alpha-synuclein were increased in those with Parkinson's disease compared to controls.
It has been a longstanding challenge to differentiate patient's with Parkinsonism related to another illness from those with Parkinson's disease early on. This may help neurologist's make a diagnosis sooner as we anxiously await a cure.
