Changes in the sense of smell could be an early sign of cognitive decline diseases like Alzheimer’s and dementia, new research suggested.
According to Knowridge, research done by the University of Chicago Medicine found that gradual loss of sense of smell could indicate future diseases linked to memory.
The study published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association analysed the data from the Memory and Aging Project (MAP) to determine that the people who experience a rapid decline in their sense of smell later showed signs of Alzheimer’s.
Dr. Leah Alexander, a paediatrician in New Jersey who was not a part of the study, explained, “This may be due to the fact that olfactory neurones (or those that detect odours) are among the most vulnerable to damage from beta-amyloid, one of the proteins associated with Alzheimer’s disease.”
Furthermore, Alzheimer’s is a disease that typically begins with memory loss and can gradually lead to confusion and trouble in daily tasks.
As per the report, more than 6 million people in America have Alzheimer’s. However, the studies suggested that a Mediterranean diet with fruits, vegetables, and healthy fats could improve brain health.
