N: 1. – Wernicke (pn): Carl Wernicke (1848-1905) was a German neurologist who related nerve diseases to specific areas of the brain.
– aphasia (n): from Modern Latin aphasia, from Greek aphasia “speechlessness,” abstract noun from a- “without” + phasis “utterance,” from phanai “to speak,” related to phēmē “voice, report, rumor”
2. In Wernicke’s aphasia, language comprehension is impaired, but the production of fluent speech is not very affected. This type of aphasia is also known as ‘fluent aphasia’ or ‘receptive aphasia’.
3. Wernicke’s aphasia is caused by damage to Wernicke’s area, an area of the brain that includes left posterior temporal regions of the brain. It is important for processing the meaning of words and spoken language.
4. Patients of Wernicke’s aphasia often speak using grammatically correct sentences with normal prosody. However, their sentences often make little sense and include a variety of irrelevant or non-existent words. They may not realize that what they’re saying doesn’t make sense. Their language comprehension is severely impaired, as is their ability to read and write.
5. Human Diseases – Various; Nervous System: Wernicke’s aphasia.
- Wernicke’s aphasia causes difficulty speaking in coherent sentences or understanding others’ speech. Wernicke’s aphasia is the most common type of fluent aphasia.
6. Wernicke aphasia (Pathology).
– Association with Wernicke area:
- Wernicke area, region of the brain that contains motor neurons involved in the comprehension of speech. This area was first described in 1874 by German neurologist Carl Wernicke. The Wernicke area is located in the posterior third of the upper temporal convolution of the left hemisphere of the brain. Thus, it lies close to the auditory cortex. This area appears to be uniquely important for the comprehension of speech sounds and is considered to be the receptive language, or language comprehension, centre.
- Damage to the temporal lobe may result in a language disorder known as Wernicke aphasia. An individual with Wernicke aphasia has difficulty understanding language; speech is typically fluent but is empty of content and characterized by circumlocutions, a high incidence of vague words like “thing,” and sometimes neologisms and senseless “word salad.”
