Adults over the age of 45 "should be cautious" as they stand to be part of an age group that is more at risk of injury, or fatality when snow shoveling, an American Heart Association spokesperson ...
There is an answer column on the back of the test booklet, and the test is scored out of 40 items. The score is compared to scores in a normative database from 4000 normal individuals, this tells the level of absolute smell function. [1] The score also indicates how the patient does in accordance to their age group and gender.

The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
New research suggests that the decreased ability to identify certain odors may signal early-stage Alzheimer's disease and future cognitive decline.
The new generations of dynamic dilution olfactometers quantify odors using a panel [5] and can allow different complementary techniques: odor concentration and odor threshold determination, odor suprathreshold determination with comparison to a reference gas, hedonic scale assessment to determine the degree of appreciation, evaluation of the relative intensity of odors, and allow training and ...
University of Chicago researchers have come up with a new test, which they believe can tell if a person has an increased risk of dementia -- it's a smell test with five different scents.
