Scientists have made a groundbreaking discovery that could lead to new therapies for Alzheimer’s disease. When mice with the condition inhale menthol, their cognitive abilities improve. Researchers found that menthol can reduce inflammation in the brain, which is often associated with the disease.
The study, published in April 2023, focused on the role of smell in the immune and central nervous systems. The team discovered that short exposures to menthol can prevent cognitive decline in mice with Alzheimer’s and even improve their cognitive abilities. This effect was also observed in healthy young mice.
The researchers believe that menthol may be able to harness the body’s natural inflammatory response, which is regulated by a protein called interleukin-1-beta (IL-1β). By reducing IL-1β levels, menthol inhalation can slow down cognitive decline. The study also suggests that certain smells may be used as therapies for Alzheimer’s disease.
While this research is promising, more studies are needed to confirm the results in humans. However, it provides an exciting opportunity to explore the connection between smell and brain function, which could lead to new treatments for Alzheimer’s and other diseases related to the central nervous system.
