LOSING your sense of taste or smell might not rank very high on the list of things to worry about. Going blind or deaf would surely be worse.
Yet anosmia, as it is called, has a disproportionately negative effect. Deprived of the pleasure of eating and drinking, anosmics often descend into depression. With around 1 in 20 people affected – more than are visually impaired – the condition is responsible for an awful lot of human misery.
One of the reasons anosmia is so devastating is a lack of awareness. Doctors often assume nothing can be done and send patients away to suffer in silence (see "Living without smell or flavour"). Research is low priority and funding for treatment is scarce.
