Human health is important and this article focus on recent news on about dementia. According to an article published on Medical News Today on November 16th, 2015, early on set of dementia may be linked to a decrease in sense of smell. Decline in cognitive and olfactory lo9ss has in previous studies been associated with anosmia or olfactory loss.
The inability to identify smells have been linked with the plaques and tangles in the olfactory bulb by autopsy studies done. Delay of dementia can b e prevented by early detection and impairment of the olfactory could be an important start. According to the article, olfactory impairment can be an important clinical marker of the disease that can help delay or prevent it’s onset.
Assessments were done by Rosebud Roberts of the Mayo Clinic in Rochester, MN, on the sense of smell of 1,430 individuals with normal cognitivity and an average of 79.5 years half of which were men and half women. They were enrolled and clinically evaluated in a prospective Mayo Clinic Study of Aging between 2004 and 2010 at every 15 months through 2014.
Six non food and six food-related smells such as bananas, chocolate, onions, cinnamon, gasoline, lemon, paint thinner, rose, soap, smoke, and pineapple among others were used in the test. The authors identified 250 new cases of MCI among the 1,431 participants in a span of 3.5 years.
The smell test score showed that there was an association between an increased risk of amnestic MCI (aMCI) and the decreasing ability to identify different smells. However, according to the article, there was no association between nonamnestic MCI and the score for a decreased sense of smell.
In addition, according to the research, people with amnestic MCI have severe memory problems. The good news is that the memory problems do not affect their daily life completely. People with dementia will find this information useful because they will understand their health condition better.
