While both men made significant contributions to the field of aphasia, it was Carl Wernicke who realized the difference between patients with aphasia that could not produce language and those that could not comprehend language the essential difference between expressive and receptive aphasia.
Site of Lesion It is hypothesized that this type of aphasia occurs when Broca's area, Wernicke's area and the arcuate fasciculus are undamaged but are cut off from the rest of the brain by infarcted tissue.

The communication is non-fluent, meaning that their average sentences are five or fewer real words.
Characteristics According to Goodglass and Kaplan the hallmark of this syndrome is extremely well-preserved repetition abilities in the context of no comprehension and no propositional speech. Characteristics The boundary between anomic aphasia and Wernicke's aphasia is fuzzy, but classic cases of each syndrome can be readily distinguished from one another.
A clinical study revealed that singing and rhythmic speech may be similarly effective in the treatment of non-fluent aphasia and apraxia of speech. Mixed Nonfluent Aphasia This diagnosis is given to patients who produce language that is similar to the telegraphic speech characteristic of Broca's aphasia, but cannot be categorized as actually having Broca's aphasia due to the severity of their auditory comprehension deficits.
Repetition is typically poor. In the past, it has been believed that the area for language production differs between left and right-handed individuals. Naming or word finding problems are the major feature of the syndrome. Glucose consumption occurs in regions where the brain is active.
He or she usually understands speech well and is able to read adequately, but writing ability may be poor.
This lack of concern is indicative of the more severe cognitive problems that give Wernicke's patients a worse prognosis than Broca's. Recovery may also be caused in very acute lesions by a return of blood flow and function to damaged tissue that has not died around an injured area.
The current behaviors and interactions of the patient will provide the therapist with more insight about the client and his or her individual needs. The procedure is a painless and noninvasive method of stimulating the cortex.
Poor repetition, in comparison to problems with comprehension and spontaneous expression, is the hallmark of this syndrome. This phenomenon is called conduit d'approche Goodglass and Kaplan, Prior to being assessed by me he had been diagnosed as having Wernicke's aphasia.
The most common cause of aphasia is a stroke, but other causes are brain tumors, head injury, or other neuralgic illnesses. Patients may distort words by adding syllables or by adding sounds to a word which are called intrusive additions.
They typically have a severity rating of 3 or 4 1 being very poor and 5 being relatively intact. Treatment is individualized based on the patient's own priorities, along with the family's input.
Patients who experienced an ischemic stroke may recover in the days and weeks following the stroke, and then experience a plateau and gradual slowing of recovery. Writing is typically similarly affected, and reading may be reduced.
Dad and Peter H In order to determine region specific properties, high glucose consumption regions are depicted in color code shown in a PET scan. According to Goodglass and Kaplan,speech is paragrammatical. It is also seen in a variety of dementias.
Characteristics Spontaneous speech is usually fluent.
Site and extent of lesion greatly impacts recovery. If one ignores the content, the form of the patient's speech may sound normal. Although less common, group treatment has been shown to have advantageous outcomes. However if the noun is reversible, such as the dog chased the cat, then their ability to recognize the sentence drops 3.
Spontaneous speech is better than repetition. The omission of function words makes the person's speech agrammatic. Misarticulations or distortions of consonants and vowels, namely phonetic dissolution, are common.
And even though treatments are available to help the aphasia regain some communication skills, what is lost is lost. Similar symptoms have been seen in a patient with left hemisphere damage whose first language was British Sign Language further showing that damage to the left hemisphere primarily hinders linguistic ability, not motor ability.
Lesions in area 37 are known to cause anomia. Patients can repeat very long, complicated utterances. Individuals with Broca’s aphasia have trouble speaking fluently but their comprehension can be relatively preserved. This type of aphasia is also known as non-fluent or expressive aphasia.
Aphasia is the inability to understand speech or to produce fluent and coherent speech. Broca’s aphasia is a type of aphasia characterized by a lack of fluency of speech, usually with preserved language comprehension. Unlike Broca's aphasics, Wernicke's aphasics tend to have anosognosia (lack of awareness) of their communication problems (Davis, ).
They often seem unaware of their speech problems. Or, at least, they are not concerned about them. In the same case studies by Caramaza and Zurif with Broca's aphasics, in which irreversible and reversible nouns were placed in sentences, Wernicke's aphasics tested poorly on both occasions.
Thus, Wernicke's aphasics have lost a majority of their comprehension ability. Broca’s aphasics and comprehension In the early ’s it was discovered that Broca’s aphasics don’t just suffer from impaired production, but also exhibit comprehension problems, especially with more complex syntactic structure.
Broca’s aphasia is named after the French scientist, Paul Broca, who first related a set of deficits associated with this type of aphasia to localized brain damage.
He did this inafter caring for a patient who could only say the word “tan”.Can broca s aphasics write a prisoner
