Swedish researchers have discovered that people who struggle with detecting scents might be experiencing symptoms of Alzheimers, Parkinson’s and even diabetes. This important new information is easy to look out for when protecting your own health.

The researchers examined rats already affected by type 2 diabetes – because this disease is often linked to brain conditions such as Alzheimers and Parkinson’s. These rats demonstrated nerve cell changes, which made it difficult for them to identify certain odours.

“The findings might explain why type 2 diabetic patients often experience smelling problems, and potentially open up a new research field to develop preventive therapies against neurodegenerative diseases in type 2 diabetic patients”, said a report published in Science Daily.

An ability to detect specific smells was slowly restored to each rat with the use of anti-diabetic drugs. These medications mimicked insulin and other hormones that normally occur naturally. Scent is often something we take for granted, but if you notice changes in your ability to smell, it’s advisable to speak with your GP.

Are you suffering with diabetes? Is somebody you know affected? What signs to you watch out for, to protect your personal health?

    A decrease in the sense of smell is not uncommon as we age, just as our eyesight and hearing can diminish. But it’s certainly worth mentioning to the GP if your sense of smell has significantly deteriorated.

    I lost my sense of smell several years ago…gradually, after experiencing the most appalling and overwhelming smell that srayed in my nostrils for weeks. Can occasionally get a faint whiff of something now…but usually smell nothing

      The lack of sense of smell can also be due to a lack of zinc.
