Nova Scotia researchers are looking for healthy volunteers between the ages of 40 and 75 to take scratch-and-sniff tests in a quest to diagnose diseases like Parkinson’s earlier.
Good’s team is made up of a fluctuating number of people, mostly from Dalhousie, usually numbering around 12. They come from fields that include neuropsychology and psychiatry.
They are mainly interested in people who do well or poorly on the smell test. These are the subjects who then come into the clinic for cognitive testing, an MRI scan and a sleep study.
