This week we will discuss olfactory disorders, or problems with smelling either good or bad chemicals, foods, fragrances, and the like. Did you know your sense of smell also affects your taste? A damaged sense of olfaction is severely disrupting: the joy of eating and drinking may be lost, and depression may result. There could also be dangers associated with the loss of smell, including the inability to detect leaking gas or spoiled food. More than 2.7 million people in the United States have an olfactory disorder, and this is likely an underestimate. Some people have suggested that about half of people over the age of 60 have a decreased sense of smell.
