This doesn’t smell good: apparently, scientists have now found a link between the impaired ability to recognize and remember smells, and an increased risk of Alzheimer’s. With a new study published in the Annals of Neurology, researchers at the Massachusetts General Hospital have developed a non-invasive test that demonstrates that deficits in odor identification correlate with Alzheimer’s disease biomarkers and cognitive decline. The good news is that if this test is validated after further research, it will provide the opportunity to detect Alzheimer’s at a very early stage, which may then allow for new therapies to slow down or even halt progression of the disease. So take a deep breath, and Read Here.
