When asked what are the typical symptoms of anosmia, Professor Hopkins replied: “Anosmia is the inability to smell things.
“The loss of smell can be very sudden, as with head injuries or viral infections, or may come on more gradually, with age related loss. It affects includes both good and bad odours – such as strong coffee or a baby’s nappy.
“Other than the obvious symptom of not being able to smell, anosmia can also appear to affect our sense of taste.
“We only really taste sweet, salty, sour, bitter or meat tastes, and all the rest of flavour comes from our sense of smell.
“So, when we lose this it impairs our ability to detect flavours when we eat, and food tastes very bland”
