Researchers have developed a device that might help doctors identify the early stages of neurodegenerative diseases such as Parkinson's. The Sniff Magnitude Test measures a patient's sense of smell, which can be one of the first indications of a brain disorder. Using a nasal tube attached to a plastic container, researchers release chemical vapors that expose a patient to different smells.
