ABSTRACT=The parosmia is a distorted olfactory sensation in the presence of an odor that can affect the quality of life of most of the patients who experience it. Qualitative olfactory dysfunction, such as parosmia, may be clinical condition secondary to neurological diseases. The incidence of parosmia is underestimated as well as its association with neurological diseases, due to poor self-reporting of patients and lack of objective methods for its measure. In this paper, we show selected clinical cases of parosmia associated with neurological disorders, such as traumatic brain injury, mesial temporal sclerosis and multiple sclerosis.This clinical cases have show how the correct diagnosis of parosmia can represent the tip of the iceberg of important underlying neurological disorders and be a good prognostic indicator of their progression or recovery.
