The Latest study shows that blood test makes Parkinson's disease diagnosis easier circulated on the Journal of the American Academy of Neurology on Feb 28. Through blood tests, it is easier to tell apart Parkinson's disease from similar disorders.

Mayo Clinic itemized common, but distressing symptoms of Parkinson's disease include slowness of movement, tremors, unsynchronized movement, trouble with walking, and problems with balancing. What follows are the least recognizable indicators which include depression, insomnia, anxiety, fatigue, and constipation. When these are seen from a person, it is best to see a doctor not just to determine any disorder, but to rule out the symptoms and conclude if what particular disorder there is.

Associate Professor of Lund University in Sweden Dr. Oskar Hansson, lead author of the latest study said, "This can be very challenging, especially during the early stages of the diseases and if the responsible doctor is not a neurologist specialized in movement disorders. Non-specialists of Parkinson's disease do not really know exactly what questions to ask the patient and the special signs to look for." In his professional view, getting the right diagnosis is an instrumental step in providing the right treatment for patients, reported on CBC News.

"We still lack an easily accessible disease-specific diagnostic biomarker for the most common movement disorder," written on the Journal editorial of the American Academy of Neurology. In analyzing if the biomarker for Parkinson's disease, one must be first validated with two or more groups of patients to ensure results are reproducible.

Results in the study with patients, nerve protein levels have a remarkable number of those with atypical parkinsonism compared to those people with Parkinson's disease. In both Sweden and the UK, blood test sensitivity average of 81 percent, while specificity average is 90 percent. This means that the blood test shows the same accuracy than the old method of getting the spinal fluid test.
