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.
Paul discovered the area of the brain now referred to as the Broca’s area. In 1861 Broca’s provided consultations to an aphasic man named Tan. He was named “Tan” because “Tan” is all he was able to say. Unfortunately sometime after Tan died and Broca’s performed an autopsy on his brain. While preforming the autopsy Broca’s found that there was damage to the left hemisphere towards the back and bottom of the frontal lobe. This area later became known as the Broca’s area.

This symptom can occur as a result of various different brain injuries. In stroke, the deficit is usually sudden and obvious. In head traumas, the aphasia may be undetectable. Exceptions are hemorrhages or traumatic contusions directly disrupting the left hemisphere language cortex, which may resemble stroke patterns. There are a variety of language disorders in dementia.
Language disorders in dementia come in various forms. For example, issues with language may be gradual and may require the assistance of an experienced physician, speech pathologist, or neuropsychologist. Some dementias, such as frontotemporal dementia, primary progressive aphasia, or Pick disease, have aphasic syndromes that are similar to the aphasic stroke syndromes described above, except that they begin gradually and progressively worsen. If aphasia is the only deficit for two years or more then primary progressive aphasia can be
W.C.’s speech difficulties were first observed at the hospital following a left hemisphere stroke by her neurologist. The client has not received previous treatment for these symptoms. The client has no history of speech and language treatment or problems. W.C. exhibits no hearing loss or vision difficulties.
Part one of Oliver Sack’ book, “The Man Who Mistook His Wife for a Hat”, is about losses. The impairment or incapacity of neurological function of those who have loss or lack some of the functions of their brain. Neurological impairments that categorize with loss of functions are loss of vision, speech, language, memory, dexterity, and identity. Some of the diseases or dysfunctions that classify these impairments are Aphonia, Aphemia, Aphasia, Alexia, Apraxia, Agnosia, amnesia, and Ataxia (Sacks 3). It was Paul Broca in 1861 who began the study of the relationship between the brain and mind when a patient case had damaged to the left hemisphere of the brain resulting in aphasia, loss of speech. It was due to this to which it paved the way
Dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. These changes are often small to start with, but for someone with dementia they have become severe enough to affect daily life.
As mentioned above this disease affects three areas of the brain; the language (difficulty with
This weeks reading discussed the brain and many complicated factors that go along with it. The brain has been an important area of study for decades and there are many different perspectives when it comes to how it works. Brain imaging, like what is discussed in the reading provided by Dr. Gordon Rose entitled "Postcards From the Brain" has shown us more information about how the brain works, but it has also led to many perspectives related to how consciousness works, and hard versus easy problems in the brain. It debates whether hard problems even exist. Furthermore, the reading provided, also describes language in a baby's brain, how mimicry works, and disorders throughout human development. These sections all involve slightly different perspectives when it comes to how our mind works.
This section describes a type of dementia known as frontotemporal dementia, which has different forms including behavioural-variant frontotemporal dementia, progressive non-fluent aphasia and semantic dementia.
Broca is mainly known for discovering specialized functions in different parts of the brain. He was able to show who had lost the ability to speak, which caused damage to a specific area to the brain by using post mortem analysis. The area, located toward the front of the brain's left hemisphere, became known as Broca's convolution. Language permits humans to generate a number of messages allows the flow
(2) Progressive non-fluent aphasia (PNFA) is characterised by problems with speech production. Individuals may struggle to find the correct words when engaging in conversation. Often individuals will struggle to pronounce words correctly (especially if they have more than two syllables), and their speech will lack appropriate grammar. Problems understanding speech can also be present, especially if the sentence contains complex grammar.
Our ability to partisipate in a conversation is made possible using our temporal lobe and the broca's areas of the brain. The broca's area is responsible for our speech production, comprehending language processing these languages, and helping a person to control facial neurons. These bundles of anatomical fibers can be found in the frontal lobe of the cortex. Composed of the pars triangular and the pars operculas; two primary parts. The pars triangular can be located in the broca's area. This part of the brain is believed to help interpret multiple modes of stimulus. the broca's area is where we organize and respond to verbal conducts. The pars opercularis can be found in the broca's area of the brain; supporting only one stimulus mode. Pars opercularis assist with coordinating the organ's used for producing speech and language because it is located near the area's of the brain that are related to our motor skills.
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 Broca's area is a part of the brain responsible for our ability to speak and communicate. This part of the brain is also involved with language comprehension as well as hand movement. While engaging in conversation the hippocampus will be responsible for the long-term memories specifically facts and events. Memories
Pierre Paul Broca was one of the earliest and most influential physicians and anatomists of his time, who in the 1860s conducted some of the first work on the effects of brain damage on behaviour (Harley, 2008). In 1861 Broca worked as a surgeon in Bicêtre general infirmary, where on 11th April, a 50 year old patient called Leborgne was transported from the main hospital of Bicêtre, suffering from diffuse gangrenous inflammation of the entire right inferior limb (Broca, 1861). Leborgne was admitted to the hospital at the age of twenty-one being subject to epileptic attacks and exhibiting lack of ability to say anything else except the word ‘tan’. During his stay in Bicêtre it was determined that his language comprehension and intelligence were intact. On the day of Leborgne’s death on 17 April 1861, Broca performed an autopsy on his entire body. In his report Broca discussed in great detail the state of his brain, where he discovered
The thalamus resembled a coin counter commonly found in a bank. The general shape implied that they only see, hear, and sense what they want to sense. Directly below the thalamus, the lateral hypothalamus was abnormally large and ball shaped, while the hypothalamus as a whole was phallic shaped. Further within the brain, the hippocampus bore a resemblance to a petite goldfish. Finishing with the brain, we studied the occipital lobe. Strangely, this lobe was situated in the front of the brain instead of the rear. The placement didn't allow the optic nerves to cross, so the underclassman experienced life backward. These optic nerves were also only one-third of the thickness of the average upperclassman optic nerve. The decrease in optic nerve pathways led to clouded vision.
Uncontrolled profanity is found in many neurolinguistics disorders, the most famous is Gilles de la Tourette syndrome (GTS). GTS, which was first identified by Itard and Gilles de la Tourette in the 1800s, is a hyperkinetic motor speech disorder characterized by frequent involuntary “tics,” which are sudden pattern-like movements or sounds. Though it is lesser known than Tourette syndrome, aphasia can also heavily feature profanity. Aphasia is a clinical language impairment resulting from damage to the language centers of the brain, usually following a stroke, but it can also come on slowly from a slow-growing brain tumor. The exact specifics of a particular aphasia depend on the location and severity of the damage. Aphasic individuals have
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.
