loss of smell early sign in 90% of Parkinson's patients

A certain type of sleep disorder, decline in sense of smell and depression may not only be preclinical signs of Parkinson's disease (PD)- they may be part of the disease itself.

"About 90% of patients have impaired olfactory function", says Dr. Harold Roberston, professor of pharmacology at Dalhousie Univeristy in an article in the Medical Post in April 2009.

Roberton is using a smell test known as the Univeristy of Pennsylvania smell test (UPSIT) to screen brothers and sisters of PD patients, If they have a decline in the sense of smell, they do a MRI and look at the olfactory tract to see if there are any changes.

It is still too non- specific to use as a screening test for Parkinson's. But certainly a symptom worth paying attention to if it does occur.

Essential oils that may help with loss of smells include basil, peppermint. rosemary, frankincense and golden rod. To order pure oils see my website
