The inability to comprehend normal speech

Loss of the ability to comprehend speech.

Receptive aphasia, also known as Wernicke's aphasia, fluent aphasia, or sensory aphasia in clinical neuropsychology and cognitive neuropsychology, is a type of aphasia often (but not always) caused by neurological damage to Wernicke's area in the brain (Brodman Area 22, in the posterior part of the superior temporal gyrus of the dominant hemisphere). This is not to be confused with Wernicke's encephalopathy or the Wernicke-Korsakoff syndrome. If Wernicke's area is damaged in the non-dominant hemisphere, the syndrome resulting will be sensory dysprosody - the lack of ability to perceive the pitch, rhythm, and emotional tone of speech.
