My husband was born without the sense of smell. It seems to run in his family in a hit and miss fashion. For example, his mother could not smell, his mother's sister cannot smell, two of her children cannot smell, but the 3rd one can. We have two children, a daughter who can smell, and an 8 year old son who cannot. The description of the condition seems to fit each affected person, except for the part about it affecting only one member of a family. Have you heard of a condition that is hereditary? See answer
Is there any hope for a return of smell for someone who has never smelled? I have been diagnosed by several neurologists and had the round of brain MRI with contrast and other tests. No one found a cause for my anosmia. I just wondered if there is anything that could be done to restore it after 45 years. See answer
How common is congenital anosmia? Is there a cure or any treatment?
