Which condition is characterized by a loss of taste sensation?

The correct answer, which indicates the condition characterized by a loss of taste sensation, is ageusia. This term specifically refers to the complete inability to perceive taste, distinguishing it from other taste-related disorders.

To give some context, hyposmia refers to a diminished sense of smell but does not directly involve taste sensation. Dysgeusia is marked by an altered or distorted sense of taste, which is different from the total loss of taste. Anosmia is the complete loss of smell, which also does not pertain to the sense of taste. Understanding these distinctions is key to accurately identifying conditions related to sensory perception.
