Is MS Keeping Me from Smelling the Roses?

Is MS Keeping Me from Smelling the Roses?

For years, my wife and I have disagreed about smells. She smells something and I don’t. I tell her that her nose is too sensitive. She tells me to get out the air freshener.

Over the 37 years since my MS diagnosis, this conversation has happened thousands of times. But I never thought that my MS might be the reason for this dichotomy of smell sensitivity. Then I came across a story on this website about how people with MS can have a reduced sense of smell, and how that reduction can begin early in the progression of their disease. Maybe that’s why the “smell meter” attached to my wife’s nose reads differently from mine.

Smell may be a hidden MS symptom

Our noses are connected to “smell meters” in our brains by the olfactory nerve. But unlike the nerves in our spine, the olfactory nerve, for the most part, isn’t covered with myelin. And lesions aren’t seen on it, either. That’s led some researchers to believe that the olfactory nerve isn’t involved with MS. However, other researchers think there may be a connection. The MS News Today article reports that “data from some [studies] indicate a 20% to 40% olfactory impairment in MS, mostly in patients with relapsing-remitting MS but also among those with primary progressive MS.”

What does this mean?

These doctors think that smell sensitivity, or the lack of it, may be able to be used as another indication that someone’s MS is progressing; less smell means more advanced disease. In our house, however, my wife will probably put it in simpler terms: It’s my smell meter that’s busted, not hers.

    Yes, I agree with you. My sniffer is off. I use to smell everything, even as a child, my mother would complain I had to smell everything.
    We are still discovering more everyday about this disease and we both know that it takes its role differently in everyone. Best of luck and happy smelling.

    I am just the opposite, I have such an acute sense of smell I hate it! I have been told that even that could be related to MS. I have a couple of cats and can tell which one is lying next to me, not by opening my eyes, but by their body odor. I can tell the difference between Coke and Pepsi (no joke) just by smelling the glasses. Drives me (and my husband I am afraid) a little crazy, because I am constantly cleaning due to something I smell.

    Exactly the same as me. I’m known as radar nose. My smell functions in hyper-mode. I instantly smell everything that’s going on. This can be unpleasant and overwhelming.
    Additionally, I can taste every nuance in any dish and am famous in my family for knowing what’s in a recipe.
