Aphasia
In this world, humans and animals alike have come to communicate by using various mechanisms. Humans have advanced themselves beyond other organisms by using language, or a set of codes and symbols, in order to express themselves to others. Language has brought about a means to create new thoughts, to explore, and to analyze our everyday surroundings. It has also enabled us to retain past memories and to look deep into the advances for the future. However, for some individuals, this tool for communication has been plagued by a language and speech disorders, such as aphasia. Aphasia is the loss of the ability to speak or understand speech or written language. It is often detected at an early age, and contributes to the general class of speech and language disorders affecting "5% of school aged children" (1) . Aphasia is classified into three categories. The main two are receptive or sensory aphasia and expressive or motor aphasia. Receptive aphasia affects the input side and "the ability to understand spoken or written language may be partially or totally lost" (1) . Those with expressive aphasia "can speak but not find certain words or names, or may be totally unable to communicate verbally or by writing" (1) . For a majority of affected individuals, there is a combination of the two. The third type is conduction aphasia. This "involves disruption of transmission between the sensory and motor ends of the circuit" (1) . Here, individuals are able to produce speech despite the lack of connections to the input side. It seems that the ability to speak has a lot to do with your surroundings and how much emphasis was placed on developing this skill during the first few years after birth. Afterall, it's known that the first few years are critical because this is the time when the brain is "plastic" and is rapidly changing and being molded. By the time that adolescence is reached, the brain has become "less plastic". In this paper, I would like to explore theories proposed to try to understand the origins of this impairment.
Ongoing research has tried to pinpoint exact reasons as to why there is speech impairment for those with aphasia and other language disorders. Most theories suggest genetic and environmental implications. Is the speech disability some sort of defect from within the brain, or does the disability develop as a result of influence from your surroundings and lack of nurture from others?
The two types of aphasia discussed in class is non-fluent aphasia and fluent aphasia. Aphasia can occur when there is damage to the left hemisphere of the brain, which is the language center of the brain. People with non-fluent aphasia will say or sign random words, there will be little or no function words/signs, similar to the telegraphic stage of language development. People with fluent aphasia will be able to produce sentences with function words, but the sentences will contain miss-selected words/signs.
While the early neurological model of language broke away from the ideas of phrenology and offered a new framework for neuropsychological research, it had numerous shortcomings. It was not able to account for the fact that people with Broca’s aphasia (also known as non-fluent, expressive or agrammatic aphasia) had a variety of ostensibly diverse impairments or that some people with focal Broca’s area damage did not show agrammatic aphasia (Bookheimer, 2002).
Wernicke’s Aphasia is a communication disorder that affects one’s comprehension, therefore affecting language of both written and spoken language. Wernicke’s Aphasia is also known as fluent aphasia because individuals that have this disorder usually, for the most part, can typically express themselves using syntax and grammar but have a hard time doing it meaningfully through speech. Physiologically, when they speak, they do not realize that their speech is usually grammatically incorrect and lacks meaning behind it. People with this disorder have a hard time with auditory processing, fluently speaking, and poor repetition of what was previously said to them. Anatomically speaking, when one has Wernicke’s Aphasia this typically means that there

Alzheimer’s disease, named after Dr. Alois Alzheimer, is a disease that is on the rise in America and the rest of the world. People should learn as much as they want about this disease, because as you age, your chances of becoming an Alzheimer’s Disease, or AD, patient increases. It is estimated that approximately 3 percent of Americans between the ages of 65 and 74 have the illness, and more than half of all people over age 85 have the ailment.
Alzheimer’s disease is a complex illness that affects the brain tissue directly and undergoes gradual memory and behavioral changes which makes it difficult to diagnose. It is known to be the most common form of dementia and is irreversible. Over four million older Americans have Alzheimer’s, and that number is expected to triple in the next twenty years as more people live into their eighties and nineties. (Johnson, 1989). There is still no cure for Alzheimer’s but throughout the past few years a lot of progress has been made.

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.
This paper will delve into the functions of a neuropsychologist and how the practitioner uses these tools to assist people with the various afflictions that arise from problems in the human temporal lobe. A pivotal area of the temporal lobe and language comprehension. is the Wernike’s area. When there is damage to this section of the brain, a condition related to language problems is known as Wernike’s a phasia. Aphasia is known as a severe language. impairment but with this version the person is still able to speak fluently but are unable to comprehend written and spoken language.
In this day and age, it seems as though almost everyone has experience a loved one taken away form a very serious disease known as Alzheimer’s disease. Alzheimer’s disease is unbelievably devastating for everyone affected by it. This disease is causing major economical problems such as less occupancy in the nursing homes, and hospitals due to the rising population of elderly men and women being diagnosed with it everyday. Because there is not yet a cure for this disease and the percent of the population being diagnosed keeps rapidly rising, more time and money needs to go towards Alzheimer’s research.
Alzheimer's Disease Introduction to Alzheimer's Alzheimer's disease is a progressive, degenerative disease of the brain. It was first described by the German neuropathologist Alois Alzheimer (1864-1915). in 1905. This disease worsens with advancing age, although there is no evidence. that it is caused by the aging process.
Every era has its disease; the one debilitating killer that each individual grows up to fear and detest more than War or poverty or depression. In the sixteenth century the Black Plague swept Europe, and later Syphilis destroyed much of the New World. More recently Polio was what each mother feared would over take her child. However, each of these diseases had its own time and place, and each has all but disappeared by cure or public awareness. Unfortunately, as each disease passes away a new killer moves up through the ranks to strike fear in humanity, young and old. Currently, the United Statesí population is aging, with people over eighty-five becoming the nations fastest growing age group">(2).It should come as no surprise that the disease of the new millennium should be a disease of the elderly: Alzheimerís Disease. Effecting half the Americans over the age of eighty Alzheimerís Disease has left its victims in a world of confused dementia, and the rest of the world in a panic to find a cure">(2).
Language is the principal means whereby we formulate our thoughts and convey them to others. It allows us to disclose our fondest memories of the past and communicate our emotions. Language has been instilled in us ever since we were babies inside our mother’s womb. We often take language for granted since most of us have never had to live a life of silence. It is perhaps because of this that people who have suffered brain damage caused by strokes, gunshot wounds, brain tumors, or other traumatic brain injuries feel a loss of self when they lose their ability to speak (1) . If we can’t talk then we can’t communicate right? Wrong.
There are many studies investigating the causes of stuttering, however the etiology of stuttering still remains uncertain. According to these studies, genetic predispositions play an important role for the developmental stuttering.
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...
