Patients with Wernicke's aphasia demonstrate fluent speech, which is characterized by typical speech rate, intact syntactic abilities and effortless speech output. [3] Writing often reflects speech in that it tends to lack content or meaning. In most cases, motor deficits (i.e. hemiparesis) do not occur in individuals with Wernicke's aphasia. [4]
Paraphasia is associated with fluent aphasias, characterized by "fluent spontaneous speech, long grammatically shaped sentences and preserved prosody abilities." [4] Examples of these fluent aphasias include receptive or Wernicke's aphasia, anomic aphasia, conduction aphasia, and transcortical sensory aphasia, among others.
Wernicke's area (/ ˈ v ɛər n ɪ k ə /; German: [ˈvɛɐ̯nɪkə]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area. It is involved in the comprehension of written and spoken language, in contrast to Broca's area, which is primarily involved in the ...
Receptive aphasia (also known as "sensory aphasia" or "Wernicke's aphasia"), which is characterized by fluent speech, but marked difficulties understanding words and sentences. Although fluent, the speech may lack in key substantive words (nouns, verbs, adjectives), and may contain incorrect words or even nonsense words.
For example, many individuals who have expressive aphasia struggle with Wh- sentences. "What" and "who" questions are problematic sentences that this treatment method attempts to improve, and they are also two interrogative particles that are strongly related to each other because they reorder arguments from the declarative counterparts.

Receptive aphasia is associated with the posterior third of the superior temporal gyrus in the distribution of the inferior division of the middle cerebral artery, [3] known as "Wernicke's area", an area adjacent to the cortex responsible for auditory processing. If the damage extends posteriorly, visual connections are disrupted, and the ...
The classical explanation for conduction aphasia is a disconnection between the brain areas responsible for speech comprehension (Wernicke's area) and that of speech production (Broca's area). This is due to specific damage to the arcuate fasciculus, a deep white matter tract. Aphasic people are still able to comprehend speech as the lesion ...
Also, a person with expressive aphasia understands another person's speech but has trouble responding quickly. [21] Receptive aphasia also known as Wernicke's aphasia, receptive aphasia is a fluent aphasia that is categorized by damage to the temporal lobe region of the brain. A person with receptive aphasia usually speaks in long sentences ...
