Loss or absence of the sense of taste. It may be: general to all tastants (total), partial to some tastants, or specific to one or more tastants; due to transport disorders (in access to the interior of the taste bud) or sensorineural disorders (affecting the gustatory sensory cells or nerves or the central gustatory neural pathways); or hereditary or acquired.
[G. a- priv. + geusis, taste]
