The weakening of the sense of smell, reducing the dependency of the intensity of the odor, is perhaps the first indicator of Parkinson's disease, say scientists. According to experts, the development of the disease in a few years to occur after the first symptoms begin to appear. Scientists have made the first analysis of this kind, which showed the relationship between the sense of smell and the risk of Parkinson's disease. Men weakening the sense of smell may be a harbinger of neurodegenerative diseases 4 years before any obvious symptoms. The study included 2,267 men who tested olfaction in the period From 1991 to 1996. Participant observation of the project was carried out over the next 8 years performed. The aim was to follow was by men diagnosed with Parkinson's disease. In a study of 35 men showed the disease.

According to experts, reduces the deterioration of smell due to aging, smoking, excessive consumption of coffee, brain activity and sleep during the day. Scientists have determined that all of these conditions act as risk factors for Parkinson's disease.
