All participants took multiple choice scratch-and-sniff tests to identify different odours such as that of bubble gum, gasoline or lemons.\u00a0One hundred of them also underwent regular lumbar punctures to quantify the proteins related to Alzheimer\u2019s disease in the cerebrospinal fluid.<\/p>\n<p>The results demonstrated that people facing greatest difficulty in identifying odours were those in whom other, purely biological indicators of Alzheimer\u2019s disease, were highest in quantity.\u00a0The researchers concluded that there was a clear relationship between loss of smell and biological markers indicating the progression of the disease.<\/p>\n<p>Despite extensive research, effective treatment for Alzheimer\u2019s disease is lacking. However, if the disease process is identified well in advance through smell identification tests, and the onset of symptoms\u00a0be delayed by even five years, there can be a more than 50% decrease in the prevalence and intensity of symptoms, the researchers suggested.<\/p>\n<p><em>Source:\u00a0Neurology Journal<\/em><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-28371\" src=\"https:\/\/www.1mg.com\/articles\/wp-content\/uploads\/2017\/08\/rsz_shutterstock_554537413.jpg\" alt=\"1mg\" title=\"Difficulty in identifying simple odours may signal Alzheimer\u2019s risk\" width=\"630\" height=\"380\" \/><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[151,162],"class_list":["post-28370","post","type-post","status-publish","format-standard","hentry","category-1mg-news","tag-mental-health","tag-neurologic-disorders"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.1 -
