What is Ageusia?
loss of the sense of smell
unpleasant taste sensation
loss of tongue taste function
Ageusia is the loss of taste functions of the tongue. It is sometimes confused with anosmia – a loss of the sense of smell. Because the tongue can only indicate texture and differentiate between sweet, sour, bitter, salty, and umami, most of what is perceived as the sense of taste is actually derived from smell.
