New device sniffs out olfactory disorders that could be an early warning of Alzheimer's, Parkinson's

The Sniff Magnitude Test (SMT), an invention of UC Psychology Professor Robert Frank and Professor Emeritus Robert Gesteland of the UC Department of Cell Biology, is now under further development with the WR Medical Electronics Company in Stillwater, Minn. The company will manufacture and market the test.

Ropinirole reduces "off" time in Parkinson's

Parkinson disease patients taking the drug, ropinirole 24-hour prolonged release significantly reduced their daily "off" time in which Parkinson's symptoms like tremor, slowness, stiffness, and walking difficulty return as drugs wear off, according to a study published in the April 3, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology.

Chemical cues turn embryonic stem cells into cerebellar neurons

Embryonic stem cells have shown a great deal of promise for alleviating heart disease and regenerating organs. But for some of the conditions for which people hold out the most hope - Alzheimer's and Parkinson's, for example - there's been little evidence to date that stem cells can work.
