Aphasia is a common language disorder. Approximately, 1 in 250 people in United State of America suffer from aphasia according to the estimation of National Institute of Neurological Disorder and Stroke. Fifteen percent of individuals who are under 65 years old are diagnosed with aphasia, the percentage will be raised to 43% in a group of people at the age of 85 or older. People who are diagnosed with aphasia commonly show significant impairment in language and communication skills, consisting of the abilities of writing, reading, verbal expression and auditory comprehension, or significant degeneration in language communication after brain injury (normally a stroke).
Patients with aphasia suffer from similar symptoms. The first one is verbal

The idea of categorizing the illness by characteristics and possible damaged brain region is initiated by Paul Broca and Carl Wernicke. People with expressive aphasia have a clear thought about what they are going to say yet they still have difficulties in communicating with people. They still need to pay effort on their speeches and they can not produce complete sentences. The injury causes this kind of aphasia is in the Broca’s area of the left hemisphere. Thereby, people with Broca’s aphasia always have impaired movement on the right side of body. Another major type of aphasia is named as Wernicke’s aphasia, also known as receptive aphasia. A person with Wernicke’s aphasia can speak fluently, however, lack of comprehension. They have no understanding of what they are reading or saying. Even they have fluent conversations, those conversations miss parts or make no sense. Although it is in the left hemisphere, same as the injury of expressive aphasia, the difference is the Wernicke’s aphasia injury is on the posterior left temporal cortex rather in the anterior area. The last major subtype is conduction aphasia, a aphasia where conversation remains fluent and comprehended, but patient may still have repeat difficulty. The damaged brain region is located in the arcuate and the left parietal
Human beings occasionally suffer bad damage to particular parts of their brains. Unfortunately, these injuries may lead to major failure of speech production, understanding language and comprehension which most of the patients suffer it permanently. This impairment is called Aphasia. Gayle (2012) states that people with aphasia fail to understand sentence comprehension although it is a simple sentence. She also mentioned that aphasia patients also have difficulty in reading and understanding speeches. According to Fromkin, Rodman and Hyams (2011), aphasia is a scientific term used to explained language disorder due to brain injuries caused by diseases or trauma. In other words, aphasia involves partial or total loss of the ability to
The topic of this annotated bibliography is communicating with people who have Aphasia. Aphasia is neurological condition that occurs when the tissues in the left hemisphere of the brain that are responsible for speech, reading and writing are impaired (National Institute of Neurological Disorders, 2013). The main signs of this disorder are: trouble in articulating oneself when speaking, difficulty understanding speech, and problems with reading and writing. Aphasia is usually caused by a stroke, severe head trauma, brain tumors, and brain infections (National Institute of Neurological Disorders, 2013). Aspasia is more common in elderly individuals, The National Institute of Neurological Disorders and Stroke (NINDS) states that Aphasia will occur in 15% percent of persons under the age of 65 and will increase to 43% for people that are 85 years of age and older (National Institute of Neurological Disorders, 2013).
The ability to do so is achieved through a compilation of neurons in the superior temporal gyrus within the left hemisphere of the brain, and this lesion is known as Wernicke's area. The type of aphasia associated with this area is known as Wernicke’s aphasia, which is identified as the opposite of Broca's aphasia: being that poor speech and fluent meaningless utterances are prevalent in patients with Wernicke’s aphasia. Due to damage in the brain’s Wernicke area or a fracture in within the auditory system, a patient may develop pure word deafness. This type of deafness allows patients to hear however they are unable to process the meaning of linguistic speech. Transcortical sensory aphasia is a type of disorder which links the Broca and Wernicke areas of the brain: patients with this speech problem typically can follow repetition but cannot produce meaningful speech on their own. The connecting fibers of axons that link the two lesions of the brain that cause transcortical damage are the arcuate fasciculus neurons. Another sort of aphasia is conduction, where the patient is unable to speak words through repetition but they can speak normally and understand the speech of others. Anomic aphasia is where the patient has difficulty choosing the correct word to use in order to prompt controversial exchanges: they use what is known as circumlocution and that is the
SPLP 634 - Aphasia. Aphasia is a major course in the curriculum with emphasis on acquired communication disorders, including the etiologies, characteristics, anatomical/physiological, acoustic, psychological, developmental, and linguistic and cultural correlates. Aphasia is a graduate-level seminar-based course directed toward the study of acquired neurogenic language and cognitive disorders due to lesions of the central and peripheral nervous systems. Four major neurogenic disorders are addressed including: the aphasias, right hemisphere syndrome, traumatic brain injury (TBI), and dementia. An introduction to the language found in neurogenic psychopathology are also discussed. Etiological factors that affect varied cultural groups (e.g.,
The dysfunction I choose to write about is Aphasia. I choose Aphasia because I have always been very interested in the brain and how important its function is to quality of life. Aphasia is a communication and comprehension disorder that is a result of damage to the area of the brain responsible for language. This area is usually located on the left side of the brain. Aphasia was discover by a French neuroanatomist name Paul Broca’s.
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).
Aphasia is a language disorder that can be the result of a brain injury. An individual that is suffering from aphasia may experience difficulty speaking, writing, reading, or comprehending. There are three different types of Aphasia that differ in various ways. First, Wernicke’s Aphasia is the inability to grasp the meaning of words and sentences that have been produced by another individual. This type of aphasia is also known as “fluent aphasia” or “receptive aphasia”. Wernicke patients’ speech may come across like a jumble of words or jargon, but it is very well articulated and they have no issue producing their own connected speech. If the patient is consecutively making errors, it is common for them to be unaware of their difficulties, and not realize that their sentences don’t make sense. The severity of the disorder varies depending on the patient, and the disorder results form damage in the left posterior temporal region of the brain, which is also known as Wernicke’s area.
In general, aphasia is the impairment of language functions due to localized brain damage. The three types of aphasia include Broca’s aphasia, Wernicke’s aphasia, and conduction aphasia. Broca’s aphasia involves reduced amounts, distorted articulation, and slow effortful speech. Wernicke’s aphasia involves a person being able to produce fluent speech, but if often difficult to make sense of. Conduction aphasia involves mispronouncing words, disrupted speech due to pauses and hesitations, and problems with repeating words said by someone else.
The participants for this experiment will be randomly selected from both Doctors Hospital and Laredo Medical Center (LMC) and will consist of aphasic patients from both genders. The group age will be from 25-65. This experiment will use random assignment when forming
One of the rarest types of aphasia includes Transcortical Sensory Aphasia (TSA) and Transcortical Motor Aphasia (TMA), which also has minimum amount of research, compared to other types of speech disorders. Patients with Transcortical Sensory and Motor Aphasias are most similar to Broca’s and Wernicke’s aphasia but differ by their repetition skills. Differentiating features including salient features, neurological relation, speech, voice, and/ or swallowing deficits, assessments, and current SLP treatments set these two Aphasias apart from other speech disorders.
Aphasia is a disorder that causes damage to several parts of the brain that are responsible for language, it gets in the way of a person’s capability to comprehend words. The area of the brain that is responsible of language is the left side of the brain. Aphasia usually occurs when someone gets a stroke or a serious head injury, but it may also develop slowly by the cause of a brain tumor, dementia or an infection, Aphasia impairs the expression and understanding of language and it also affects reading and writing. It may occur with speech disorders as well such as dysarthria or apraxia of speech, which is also caused from brain damage. The causes of aphasia are damages to one or more areas of language in the brain, or sometimes brain injury
Primary Progressive Aphasia (PPA) is a neurodegenerative disease in which early symptoms are characterized by gradual disturbances of the language function while other cognitive functions remain preserved. These deficits of the language function tend to worsen over time and vary between patients. Three cardinal aphasic variants have been identified in PPA and designated as nonfluent (nfvPPA), semantic (svPPA) and logopenic (lvPPA), each with a characteristic pattern of atrophy and underlying pathology.
Later that night, I researched expressive aphasia online. Behavioral science classes had exposed me to the subject, but they didn’t offer a solution to communicate effectively with this patient. Videos and articles instructed to speak directly and simply and be patient. The next day, I spent some extra time with the patient. Thanks to the use of a communication board and the lessons from my research, he finally explained what he needed and how he felt. I learned an important lesson that day: persistence and patience, even in
You provided good definitions of different types of Aphasia and what is affected according to the area that is damaged. You also provided great examples of each. According to Nlm.nih.gov (2015), “expressive aphasia may be non-fluent, in which case a person has trouble finding the right words, saying more than one word or phrase at a time, and speaking overall”. Like you had pointed out, this is very devastating.
As Thompson states, “A sufferer of Broca 's aphasia may understand completely the sentences of others. However, he may not be able to speak at all, or may speak in sentences that are hard to understand” (Thompson, 2013). Toivonen, a professor at Carleton University, discussed the significance of information flow in the brain using the example of reading out loud. This example illustrates the phenomenon that when an area of the information pathway is damaged, correspondingly, the message-relay can become interrupted. First and for most, the process of articulating begins with the Wernicke’s area of the brain activating when an individual accesses and interprets the lexicon, their mental dictionary. From there, the arcuate fascicles, a bundle of nerve fibres, transmits information sent from the Wernicke’s area to the Broca’s area. The Broca’s area then interprets this information and transmits articulatory information to the motor cortex. Finally, the motor cortex directs movement of the muscles to produce and pronounce speech. (Toivonen,
