The nose ... the latest early detection method for "Alzheimer's"

Scientists from the Daegu Gyeongbuk Institute of Science and Technology in South Korea have provided a new path in discovering signs of Alzheimer's disease, by analyzing nasal secretions.
In previous studies, the institute's scientists discovered distinctive properties in the olfactory systems of mice with Alzheimer's disease, which arose from the accumulation of what is known as "beta-amyloid" in the peripheral olfactory system, which are toxic protein complexes in the brain, believed to be major drivers of neurodegeneration associated with dementia. And Alzheimer's disease.
Scientists recently discovered that these clusters are soluble and can detect nasal secretions as an important component in monitoring disease progression.
The scientists recruited 39 patients with Alzheimer's disease and 21 patients in the same age group to compare the results. The comparison revealed that levels of two beta-amyloids were significantly higher in those with Alzheimer's.
Scientists believe that the vital "amyloid beta" can not only be used to diagnose Alzheimer's, but also to predict its progression.
"Routine nasal secretion examinations may be a better option for screening for the disease due to their various advantages, such as their relatively low cost and non-invasive nature," said Professor Shell Moon.
