Saliva gland may hold key to Parkinson's diagnosis
from Med Page Today
An abnormal protein associated with Parkinson's disease appears to accumulate in the submandibular glands, opening the way for the first good lab test for the condition in living patients. In a pilot study, nine of 11 patients with established Parkinson's disease diagnoses had phosphorylated alpha-synuclein in biopsy samples taken from the submandibular gland.
