What can smell tell us about the brain condition?
A popular article by Lenka Martinec Nováková about the relationship between brain condition and olfactory perception was published in the Vesmír journal. In general, a person’s sense of smell is usually aggravated by natural aging, which may adversely affect the individual’s quality of life. Changes in olfactory abilities may however be an accompanying sign of certain diseases such as Alzheimer’s and Parkinson’s disease, or psychiatric illnesses such as schizophrenia. Olfaction is however still not routinely examined in psychiatric care.
