Smell Loss: Early Warning for Dementia, Heart Disease?

A reduced sense of smell, medically known as an olfactory disorder, is increasingly being recognized as a potential early indicator for a wide range of diseases. Experts suggest this often-overlooked symptom could be linked to over 130 neurological, physical, and genetic conditions, impacting a significant portion of the population, particularly older adults.

Emerging research highlights a strong correlation between loss of smell and the early onset of debilitating illnesses such as dementia and Parkinson's disease. Studies indicate that smell impairment can precede motor difficulties in Parkinson's patients by several years and may signal protein accumulation in the brain regions associated with dementia.

Furthermore, evidence suggests a link to increased risks of stroke and heart failure. Given these serious implications, international experts are advocating for the integration of smell screening into routine medical check-ups. They also emphasize the need for public awareness campaigns and improved medical training regarding olfactory disorders.
