Sudden loss of smell is a sign of dementia It is well known that the disappearance of smell indicates infection with a coronavirus infection. However, scientists from the University of Chicago said that senile dementia can also be manifested by this very atypical symptom..

In recent years, COVID-19 has been strongly associated with the sudden loss of the ability to distinguish smells.. And now scientists from Chicago claim that anosmia can also be an early sign of senile dementia.. Note that scientific studies have previously associated various types of dementia with the gradual disappearance of odors.. But for the first time, scientists have shown that dementia can be manifested by a sharp disappearance of the ability to distinguish aromas..

Loss of smell can be a symptom of deadly diseases Study authors followed more than 500 older Americans for almost 20 years. Those who experienced anosmia for several years subsequently suffered from Alzheimer's disease twice as often as those who gradually lost the ability to distinguish smells over decades.. According to the authors of the study, this provides an even clearer picture of the links between odors and senile dementia.. Therefore, smell and vision acuity tests should be made routine for older people who are suspected of having memory problems..

Smell is not always lost with coronavirus While smell is sometimes considered a less important sense than sight and hearing, it still provides the brain with very valuable information.. Memory plays a critical role in the ability to recognize odors, and science has long known the link between smell and cognition..
