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.
