Wernicke’s Aphasia
Wernicke’s Aphasia
Background
Aphasia can be defined as a disorder that is caused by damage to parts of the brain that are responsible for language (“Aphasia” n.p.). Wernicke’s aphasia is a type of fluent aphasia (with the other type being nonfluent). It is named after Carl Wernicke who described the disorder as “an amnesiac disorder characterized by fluent but disordered speech, with a similar disorder in writing, and impaired understanding of oral speech and reading” (“Wernicke’s” n.p.). Wernicke’s aphasia can also be known as sensory aphasia, fluent aphasia, or receptive aphasia. It is a type of aphasia that is caused by damage to Wernicke’s area in the brain, in the posterior part of the temporal lobe of the left hemisphere. This area of the brain contains motor neurons responsible for the understanding of spoken language and is believed to be the receptive language center (“Rogers” n.p.). Wernicke’s aphasia can be most efficiently defined as a fluent language disorder commonly caused by strokes and characterized by difficulty comprehending spoken language and producing meaningful speech and writing which is both assessable by an SLP and treatable by a variety of methods.
Etiology
The onset of aphasia is extremely quick. It usually is found in people who have no former history of speech or language problems. The lesion leaves the affected area of the brain unable to function as it did only moments before (Owens 203).Wernicke’s aphasia is caused by damage to Wernicke’s area which can result from head injury, brain tumors, infections, dementia, or the most common cause, stroke. A posterior stroke that is isolated to Wernicke’s area does not result in total weakness of the arm and leg on the opposite ...

As most people know speech and language issues would only happen with children just learning to talk and tennagers in middle school to high school. The reasoning behind this is because most people don’t correct their children’s speech when they are first learning due to the fact that the parents or grandparents think it is to cute to correct, which only hurts the children more th...
The symptoms of a right-hemisphere stroke are very much similar like the symptoms Mr. Fix-it is experiencing. For example, both suggest that functions on the left side of the body are completely neglected; therefore, the left visual section of the body does not respond effectively to stimuli due to the neglect. Damage to the right occipital lobe is very likely. The patient may have experienced some damage to areas 18 and 19 of the occipital lobe. “Damage to these association areas resulted in the patient’s failure to recognize items even when they have been seen before”, such as Mr. Fix-it’s deficiency to recognize geometric shapes (Carlson, 2010). Moreover, the patient could have also experience damage in the frontal lobe, specifically on area 8, in which it could have r...
There are many different things that can cause ataxic dysarthria. For example, any type of head trauma, or vascular lesion such as an aneurysm, arterial venous malformation, or hemorrhage in the brainstem or midbrain can cause damage to the cerebellum eventually leading to ataxic dysarthria. Degenerative diseases like multiple sclerosis, Friedreich’s a...
The neuroanatomical approach to aphasia relies on the localization of lesions on the brain in addition to clinical observation in order to classify patients according to syndromes. For example, according to the neuroanatomical approach, Broca’s aphasia, which us usually associated with a lesions on the posterior inferior frontal gyrus of the brain, has cardinal features that distinguish is from other fluent and non-fluent aphasias (e.g. poor repetition, poor repetition and poor naming with good auditory comprehension).
According to the World Health Organization, 795,000 Americans suffer a stroke each year and of the survivors, twenty-five to forty percent will acquire aphasia. The National Aphasia Association defines aphasia as “an impairment of language, affecting the production or comprehension of speech and the ability to read or write.” Many of these people suffering from aphasia will undergo therapy at some point in time. Several approaches have been proven effective in lessening the symptoms of aphasia. A recent topic of interest over the last two decades has been the role that intensity plays in aphasia therapy. Several studies have been done to evaluate language outcomes for patients undergoing intensive versus non-intensive aphasia therapy, as well as to identify the specific intensive therapies that are effective. One such type of therapy is the Constraint-Induced Language Therapy (CILT). Another topic of interest in the aphasia community is regarding the “window of recovery” for those suffering from aphasia. It was commonly believed that language recovery from aphasia plateaus off within the first year following a stroke (Pedersen et al., 1995); however, new evidence suggests that when an intensive therapy such as CILT is implemented, results can be seen many years later. The present paper will investigate the role that intensity plays in aphasia therapy, take a closer look at CILT versus other approaches, and evaluate current research regarding the “window of recovery” in patients with aphasia.
Aphasia is an acquired communication disorder that disrupts communication and it can deteriorate a person’s coping potential and quality of life (Parr, 2001) which involve damage to the parts of brain that contain language (ASHA, 2013). Statistics from United States indicated around 25-40% of stroke survivors developed aphasia (National Association of Aphasia, NAA, 2013). Aphasia will affect both the ability to produce or comprehend spoken language and written language while intelligence is left intact (NAA, 2013). In US, it is found that the most common cause of aphasia is stroke (85%) and others including Traumatic Brain Injury (TBI), brain tumor or other degenerative diseases (NAA, 2013).
The article opens up with an explanation as to what the method of coaching is. According to Holland, “life coaching”, as it is called, is considered to be a variant of typical counseling. Coaching is in its early stages (as of 2007), yet it is used in developments and processes that are designed to help individuals with aphasia live their lives to the fullest and improve their quality of life. The work of Goldsmith (an earlier mentioned practitioner) is the author’s main interest. Goldsmith’s approach involves what one may call a “Buddhist” way of thinking; meaning change is seen as a positive thing. Speech-language pathologists place their trust in their client’s ability to take on new skills, arrange their new language capabilities, and acquire new problem-solving tactics.
Aphasia is present when the patient knoes what he or she wants to say but cannot pronounce it. The patient with sensory aphasia has difficulty understanding language and may articulate words easily but use them inappropriately. (Davi-Ellen Chabner The Language of Medicine 10th edition)
When talking about Wernicke’s aphasia there are also many language symptoms. Those suffering from Wernicke’s aphasia have no problem with speech, but their speech isn’t fluent and doesn’t make sense (DiNapoli, 2012, p.52). Mr. Gorgan experienced psychotic speech (DiNapoli, 2012, p. 53). If the lesion that caused this aphasia wasn’t entirely eliminated, output might slowly improve. On the other hand, if this lesion has been eliminated, the patient will more than likely not be able to talk like they once did ever again, no matter how much therapy they receive or treatment (DiNapoli, 2012, p. 54). When Grogan was told to identify objects around him, he was only successful with those most familiar to him (DiNapoli, 2012, p. 55).
Developmental dyslexia is classified as a learning disability, particularly focusing on impaired language-based learning. It is a syndrome with a neurological origin and it exists on a spectrum with varying in severity and symptoms. The neurological basis of dyslexia is not well understood, however, research has demonstrated its origin in the left perisylvian area. (Ramus 2003, Eden et al 2016) Children with dyslexia struggle with processing writing (orthography) and sound structure of words (phonology) of languages.
Usually when people ponder upon the words learning disability they think of dyslexia dysgraphia, or dyscalculia. On the other hand, in some cases some individuals have difficulty with social skills, and understanding nonverbal cues. Moreover, let’s say the same individual can read beyond his/her grade level but is unaware of the main idea or other important aspects of the story. All of the things that were stated are signs of nonverbal learning disorder (NVLD).
Dyslexia is a language based learning disorder that is grounded in the neurobiology of the brain. The disorder interferes with the processing and comprehension of both spoken and written language. Often there are other associated symptoms such as poor spelling, writing, handwriting and occasionally arithmetic (1). People do not read or write backwards as is depicted by the media. Nor is it a disorder of laziness or lack of intelligence.

Speech language pathology is another major rehabilitative medical care. Some stroke survivors area unit left with brain disorder, an impairment of language and speaking skills within which the stroke survivor will assume likewise as before the stroke, however is unable to induce the proper words out or is unable to method words coming back [32]. Brain disorder is sometimes caused by a stroke on the left aspect of the brain. Speech language pathology will teach the aphasic stroke survivor and his or her family members’ ways for dealing with this frustrating impairment. Speech language pathologists additionally work to assist the stroke survivor deal with blackout and alternative "thought" issues caused by the stroke [33].
Communication is very crucial in life, especially in education. Whether it be delivering a message or receiving information, without the ability to communicate learning can be extremely difficult. Students with speech and language disorders may have “trouble producing speech sounds, using spoken language to communicate, or understanding what other people say” (Turkington, p10, 2003) Each of these problems can create major setbacks in the classroom. Articulation, expression and reception are all essential components for communication. If a student has an issue with articulation, they most likely then have difficulty speaking clearly and at a normal rate (Turkington, 2003). When they produce words, they may omit, substitute, or even distort sounds, hindering their ability to talk. Students who lack in ways of expression have problems explaining what they are thinking and feeling because they do not understand certain parts of language. As with all types of learning disabilities, the severity can range. Two extreme cases of expression disorders are dysphasia and aphasia, in which there is partial to no communication at all (Greene, 435, 2002). Individuals can also have a receptive disorder, in which they do not fully comprehend and understand information that is being given to them. They can experience problems making sense of things. “Children may hear or see a word but not be able to understand its meaning” (National Institutes of Health, 1993, p1). Whether children have difficulty articulating speech, expressing words, receiving information, or a combination of the three, there is no doubt that the tasks given to them in school cause frustration. These children experience anxiety when...
