Researchers find the key to loss of smell with Parkinson's disease.
Parkinson's disease is a progressive, degenerative disorder of the brain. Symptoms include tremors, stiffness or rigidity, and slowness of movement. According to Parkinson's New Zealand, approximately 1 percent of people over the age of 60 have the condition. There is no cure so treatment will normally focus on managing symptoms, typically with medication.
Loss of the sense of smell is an often overlooked but remarkably prevalent early symptom of Parkinson's disease.
