Loss of smell may be predictor of death in older adults - study

[NYC_SKP]

6. Yeah, and I'm actually in the Hyposmic (partial loss) group.

Here's a link: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0107541

The Hyposmic group is about 9% and the Normosmic group about 6% compared to Anosmic group at 39%.

I can still smell things but at about 1/3 normal strength.

If I had some Sniffin' Sticks, I could determine my group. That's what they used in the study.

We treated the degree of olfactory dysfunction (anosmia, hyposmia, or normosmia) or the number of odors incorrectly identified (0–5) as the independent variable and death as the dependent variable in separate analyses.

The modified smell tests used “Sniffin’Sticks,” odor-dispensing devices that resemble a felt-tip pen but are loaded with aromas rather than ink. Subjects were asked to identify each smell, one at a time, from a set of four choices. The five odors, in order of increasing difficulty, were peppermint, fish, orange, rose and leather.

Measuring smell with this test, they learned that:

Almost 78 percent of those tested were classified as “normosmic,” having normal smelling; 45.5 percent correctly identified five out of five odors and 29 percent identified four out of five.
Almost 20 percent were considered “hyposmic.” They got two or three out of five correct.
The remaining 3.5 percent were labelled “anosmic.” They could identify just one of the five scents (2.4%), or none (1.1%).
