Recommended: Role of Semantic Memory in Language Processing

The motivation behind this paper was to fully explain Semantic Dementia in order to distinguish it from other similar disorders such as dementia of Alzheimer type (DAT), Progressive Aphasia, and Pick’s Disease. The signs, symptoms, and prognoses of Semantic Dementia were addressed in five patients. Semantic memory is long-term and contains information about objects, facts, concepts, and words and their meanings. Tasks that may be affected by semantic memory impairment include: naming, defining spoken words, word-picture and picture-picture matching, and exemplars on category fluency tests. Semantic Dementia is characterized by: (i) selective impairment of semantic memory; (ii) relative sparing of comprehension, syntax, and phonology; (iii)

Whilst Dementia primarily affects older members of the community, it can also affect young people and has a significant influence on overall health and quality of life (AIHW 2012). The type of Dementia is a determinant in the severity and development of symptoms in individuals (Department of Health 2013) (DoH, 2013). The gradual, progressive and irreversible nature of Dementia has a considerable social and physical impact not only on the individual, but also on family and friends.

  • Declarative Memory Essay

    The question then becomes whether declarative and non-declarative memory are in fact separate or different manifestations of the same neural process. From research on H.M., we find evidence for the existence of a declarative memory system that is independent of non-declarative memory and other forms of intelligence. H.M. had the capacity to hold information in his head for a period of time, suggesting that his working memory was intact (Squire and Wixted, 2011). Further evidence that not all memory is the same is the fact that H.M. acquired a motor skill despite not being able to remember actually learning the skill, thus showing the difference between episodic and semantic memory. Amnesiacs are able to acquire the perceptual skill of reading mirror-reversed words at a normal rate compared to controls (Cohen and Squire, 1980), demonstrating that the ability to learn new perceptual skills also remains intact. Of the forms of non-declarative memory, procedural memory involves the cerebellum, motor cortex, and basal ganglia (General Intro the Neurobiology…). Thus, non-declarative memory can, in a way, be seen as a more primitive form of memory that is not acquired through the integration and consolidation of neural events in the medial temporal lobe, but rather through learned associations outside of the

    A medical assistant can explain how the signs and symptoms of Alzheimer’s differ from the signs and symptoms of dementia by explaining how each medical condition works to the patient and/or their caretaker. A medical assistant can talk about how dementia is a syndrome, not a disease like Alzheimer’s. Dementia is a group of symptoms that affects mental cognitive tasks such as memory and reasoning. Alzheimer’s is a progressive disease of the brain that slowly causes impairment in memory and cognitive function. Both medical conditions are very similar, that is why many people think that they are the same exact things but they are a little different from each other.

    Dementia is defined by the World Health Organization as a syndrome due to damage of the brain cells that most often chronic and progressive in nature. Some of the cortical functions that become impaired include memory, thinking, orientation, comprehension, calculation, learning capacity, language and judgment. Other manifestations that may accompany this disease are deterioration in emotional control, social behavior or motivation (Ouldred & Bryant, 2009) Dementia is not a normal part of aging, however it occurs most frequently in the older population. Fifteen percent of Americans over the age of sixty-five have dementia, and as the average life span continues to increase, so will the number of those affected by dementia (Fredman, James, Johnson, Scholz, & Weuve, 2012).

    Dementia is a major neurocognitive disorder that interferes with the independence of the elderly by inhibiting memory and thinking skills. Fifty to eighty percent of dementia cases constitute of Alzheimer’s diagnoses; consequently Alzheimer’s disease is the most common type of dementia and currently affects 5.2 million Americans. Most of these cases are patients above the age of 65 and by 2050; 13.8 million Americans in total will suffer Alzheimer’s due to aging of the general population, specifically the baby boomers. Total cost to society ranges from $157- $215 billion (Associated Press). Some would assume the cost of Alzheimer’s to be incurred by pharmaceuticals or medical costs, however RAND Corp suggests dementia cost to society is from care rather than treatment. Therefore, assistance provided by informal providers and directs caregivers incur a majority of the financial and social cost. Currently, the workforce does not have the capacity or training to care for these unique patients; the delivery system needs to address Alzheimer’s as the population ages and more and more fam...

    It was a pleasant day at the Dementia unit and I was assigned to care for a lady whom we can call Miss K. She is a lovely, warm and nice lady who was recently admitted to the Dementia unit two weeks ago. I went to her room to meet her, I introduced myself, greeted her and gave her a hand shake for me to establish rapport. She was very cooperative, participative and independent with her cares. From my observation, I noticed that she is very organised and very particular when it comes to cleanliness. She also wakes up early in the morning and makes sure that all of the things that she needs for morning care are neatly arrange in the bathroom. When having a shower, she cleans her body very well. She also brushes her teeth and cleans her dentures very well. She always likes to wear red coloured clothes and red floral nighties. Before leaving her room, she makes sure that her glasses are clean before wearing it, her used clothes are neatly kept in the empty drawer and she wants to have a handkerchief in her pocket.
