Explanation:

"Anosmia" refers to a condition in which a person loses his sense of smell. This could either be a "temporary loss of smell" or "permanent loss of smell." A temporary loss of smell may be caused by a cold while permanent loss of smell may be caused by aging or injury to the nerves.

"Parosmia" refers to a condition in which a person's sense of smell is distorted or changed. This means that a person may think something smells awful when in reality, it smells good.
