Anosmia is when a person has lost the sense of smell. This may be caused by a severe head
injury, an infection or a blockage of the nose. The loss of smell has a very large impact on other
senses as well. For example studies show that when you cannot smell food it does not taste as good.
Without the ability to smell our taste buds can only detect a few flavors. Some common causes of
anosmia are old age, certain medications, cocaine abuse, or exposure to toxic chemicals.
