Penn expert probes possible reasons for loss of smell

(University of Pennsylvania School of Medicine) Studies have shown that loss of the sense of smell can be among the first warning signs of diseases such as Alzheimer's and Parkinson's. Now a researcher at the Perelman School of Medicine at the University of Pennsylvania wants to shift the search for clues about this process back even further, to find out if there is a common factor responsible for the loss of smell that may also serve as an early warning signal for a number of neurodegenerative diseases.
