A Link Between Loss of Smell and Alzheimer’s Disease


A study has revealed a link between a declining sense of smell and mild cognitive impairment (MCI) and Alzheimer’s disease.  Researchers found that neurodegeneration associated with Alzheimer’s has a notable effect on the brain circuits that process our sense of smell.

The 2016 study was conducted by the Massachusetts General Hospital and involved a group of 183 participants of which 70 were cognitively normal and 74 tested normal on cognitive tests but were concerned about their cognitive abilities.  Another 29 had MCI and 10 had been diagnosed with possible Alzheimer’s disease.  Those who performed more poorly on the olfactory tests were found more likely to have the variant of the APOE gene, related to an increased risk of Alzheimer’s.  One of the study’s authors, Mark Albers, MD, PhD, assistant professor of neurology at Mass General Institute for Neurodegenerative Disease, states, “There is increasing evidence that the neurodegeneration behind Alzheimer’s disease starts at least 10 years before the onset of memory symptoms.”  Furthermore, he stresses the benefit of an early diagnosis as the individuals can begin appropriate therapeutic treatments. 

Dr. Albers continues, “If these results hold up, this sort of inexpensive, noninvasive screening could help us identify the best candidates for novel therapies.”  In addition, identifying the disease early may also be instrumental in helping to develop effective treatments that will delay and slow the progress of the disease.

The Benefits of Assisted Living

Image
Studies show that for many older adults in need of a little daily assistance, life is easier in assisted living.  The reason so many of them say they prefer assisted living to living on their own, is it actuals helps them to feel more – not less – independent.  In fact, senior living communities such as MorningStar of Littleton are designed to provide seniors a lifestyle of comfort, wellness, and community.   When you live in your own home, you have the constant worry of upkeep and unexpected repairs, or you may be a person who no longer feels comfortable driving and have given it up altogether.  This makes running errands, grocery shopping and getting to doctors’ appointments difficult. Moving into assisted living means you no longer have to spend time worrying about maintaining a home, and communities such as MorningStar offer scheduled transportation.  Meal prep is another thing that is often difficult for the elderly, and as a result, many older ...
