What is a lexical Paraphasia?

Paraphasias. Paraphasias are defined as unintended utterances. In essence, there is a failure of selection at the phonemic level, producing a phonemic (literal) paraphasia (e.g., “I drove home in my lar”) or at a word (lexical) level (e.g., “I drove home in my wagon”), producing a verbal paraphasia (Table 3-3).

What part of the brain is affected by receptive aphasia?

Today, Wernicke’s area in the left upper part of the temporal lobe is widely recognized as an important brain area for receptive language. Patients with brain damage in this region and deficits in speech comprehension are still called ‘Wernicke’s aphasics’.

How does the nervous system affect speech?

Speech relies on the activation of multiple areas of the brain working together cooperatively. Broca’s area and Wernicke’s area are considered the major components of the brain involved in speech, but other parts of the brain also play an important role in coordinating the muscles of the mouth to create spoken words.

What causes verbal Paraphasia?

Verbal paraphasia Verbal paraphasias are the only type of paraphasias that can also be linked to nonfluent aphasias, and they are mainly caused by lesions to the posterior temporal region of the brain, the head of the caudate nucleus, or both.

Do people with Wernicke’s aphasia understand?

This condition is also called sensory aphasia or fluent aphasia. People who have Wernicke’s aphasia can’t understand words. They speak with regular rhythm and grammar. But the words don’t make sense.

Do people with Wernicke’s aphasia understand other people?

Aphasias are conditions of the brain that impact a person’s communication abilities, particularly speech. Wernicke’s aphasia causes difficulty speaking in coherent sentences or understanding others’ speech.

What brain part controls language?

In general, the left hemisphere or side of the brain is responsible for language and speech. Because of this, it has been called the “dominant” hemisphere.

What are verbal paraphasias?

Verbal paraphasias are confusions of words or the replacement of one word by another real word; another definition is that of a contextually inappropriate English word or an English word of a syntactically incorrect class – the wrong part of speech, for example.

What is Neologistic paraphasia?

Neologistic Paraphasia Also referred to as neologisms, is the use of non-real words in place of the intended word. Neologism literally means “new word.” These invented words do not sound similar to the intended word.

What are semantic paraphasias in aphasia?

15-1.1 Semantic Paraphasias. A common symptom in patients with a Wernicke-type aphasia are so-called semantic paraphasias. In this type of paraphasia, a word is produced that deviates in meaning from the intended word (Poeck, 1982). The actually produced word very often has some semantic similarity to the intended word.

What are semantic paraphrase errors?

These errors can be semantic, in which the meaning of the word is related to that of the intended word (car for van, for example). Semantic paraphasias can be further subdivided into six different types.
