Can someone with anosmia smell a perfume scent?
A trained sniffer dog can find hidden drugs or earthquake survivors and even detect cancer. We might not have as good a sense of smell as dogs, but we still follow our noses. Wake up and smell the coffee! Something smells fishy. She has a nose for a bargain. The English language is full of idioms to do with smell, and many of them show how important smell is to our sense of judgement.
And that's not surprising, because a sense of smell is very useful in telling when food is off, or clothes need washing, for example. But millions of people can't smell anything at all: to use a medical term, they are 'anosmic.' In the UK alone, around 3 million people are anosmic, but the country's first clinic to help them has only recently been set up.
So how do people lose their sense of smell? Some people are born that way, they are congenitally anosmic. Others lose their sense of smell because of a head injury, or illness. Those with congenital anosmia might not know what they're missing, but people who lose their sense of smell often become depressed.
