One-million americans are living with parkinson's disease. now there's a new test in the works - that could tell patients what their future looks like. Right now - there's no way to tell these parkinson's patients if they will have a mild or severe form of the disease. Melanie Lawson looked into a simple blood test the may give them a glimpse into their future. 3 0 - 6 7 - 11 27 - 33 MICHAEL WEINMAN HAS BEEN LIVING WITH PARKINSON'S FOR 14 YEARS. "I used to be able to run, I can't run anymore. I used to be able to carry my food to the table. I can't do that." BUT MICHAEL HAS KEPT A POSITIVE ATTITUDE THROUGH IT ALL. "I try to focus on what I can do though." "Definitely, he's a glass half full." WHILE MICHAEL'S DISEASE HAS PROGRESSED SLOWLY - PARKINSONS' PATIENTS DON'T KNOW WHETHER THEIR DISEASE WILL BE MILD OR SEVERE WHEN THEY ARE DIAGNOSED. "Nobody who is a neurologist and sees patients can very well predict who will rapidly decline eventually need a wheelchair quite fast." U-C-L-A DOCTOR BEATE RITZ AND COLLEAGUES STUDIED RECENTLY-DIAGNOSED PARKINSON'S PATIENTS.THEY TOOK BLOOD SAMPLES AND FOUND THOSE WITH HIGHER LEVELS OF A METABOLITE -N-8-ACETYL SPERMIDINE - DECLINED MUCH FASTER THAN THOSE WITH LOWER LEVELS. "We found that this one metabolite seemed to really distinguish these two groups from each other." MICHAEL AND HIS WIFE HOPE RESEARCH LIKE THIS WILL HELP OTHERS.THEY ALSO WALK IN THE ANNUAL "MIKE-HIKE" - WHICH HAS RAISED MORE THAN 40-THOUSAND DOLLARS FOR PARKINSON'S. "Hopefully in the future, they'll be able to treat it and recognize it sooner." 3 Doctors say the next step is to conduct a larger study on this metabolite as a predictor of faster progression.
