Diagnosed with Congenital Anosmia
I haven’t been able to smell my entire life (I put my birthday as the onset date). A doctor I went to diagnosed it as “congenital anosmia” but couldn’t do anything more for me. He prescribed an oral corticosteroid plan but I had no change in my ability to smell, so he said there’s nothing else he can do.
I’m hoping there are more resources out there. I put severe migraines as a symptom because as a young child I used to get terrible migraines so bad I would randomly fall over. I got tests done though and there was nothing out of the ordinary, and they no longer occur, so I’m not sure if that’s relevant, but I wanted to put it regardless.
I’ve tried taste testing because I know that smell greatly affects taste. When I did a blind taste test I had absolutely no idea what I was eating. However, I have favorite foods and there are things I don’t like so I know I have a sense of taste, but I just can’t recognize any specific flavors.
I’m not from New York, I’m from Pennsylvania, but I’m just hoping for some answers or some other resources or some clinical trial somewhere, or basically anything. Nobody else I’ve seen has been able to help.
First of all, thank you for your question. As you obviously realize, the loss of smell can cause many problems. We use the sense of smell to detect danger—varying from a gas leak to rotting food. The loss of smell interferes with our enjoyment of food and our daily activities.
While about 1/5 of cases of loss of smell have an unknown cause, most can be related to a viral infection, head trauma or infection. A small group are born without the sense of smell. This is called congenital anosmia.
The most common syndrome causing congenital anosmia
One can usually differentiate congenital anosmia from the loss of smell that may have occurred in infancy by an MRI of the olfactory bulb. The olfactory bulb is an area in the brain, just above the sinuses, where the smell nerves are located. The olfactory bulb may be absent in people born without the sense of smell.
Promising therapies for congenital anosmia
While we have therapies that have been shown to help for acquired anosmia, so far we do not have a good therapy for its congenital absence. Work, though, is being done. A study at the University of Michigan a few years back showed good results in treating mice with congenital anosmia.
One of the nations leading centers for the study of the sense of smell is at the University of Pennsylvania Smell and Taste Center. While we’d be happy to see you at the NY Sinus Center for this, you might start by going there for an evaluation and to see whether you may be a candidate for one of their studies.
I hope this helps clear things up.
