SNIFFING OUT DISEASES



                                      


A sniffing test may help in the early diagnosis of diseases such as Parkinson’s or Alzheimer’s. A failing sense of smell appears early in the progression of Parkinson’s disease and is among the most common symptoms.

A practical method of testing the level of deterioration in a patient’s sense of smell has now been developed.

While the more obvious Parkinson’s symptoms, such as tremors and muscular rigidity, appear at a later stage.

Dysfunction in the sense of smell can be detected months or even years earlier, thanks to newly developed sniffing test. This opens the way for treatment that may delay the progression of this presently incurable disease.
