Brain Activity in Old Age Medicine Assignment Paper (Essay Sample) Content: Brain Activity in Old AgeNameInstitutional affiliationBrain Activity in Old AgeIntroductionOver the years, aging has been observed to cause changes in both the brain anatomy and physiology. As a person ages, the brain becomes smaller and shrinks in size; vasculature supplying the brain becomes affected. The morphology of the brain molecules also changes, and the function of the neurotransmitters and the levels of the hormones in the brain become impaired (Garaschuk, 2017). These transformations are often evidenced by increased incidences of certain age-related disorders such as dementia and growing risks of stroke in the old people. The rates of such disorders are not uniform in the populations since certain protective factors counteract the changes that take place in the brain. Such activities as exercise and healthy dietary habits reduce risks associated with old age. The changes that take place in the brain also affect the memory activity. This paper studies the ch anges in brain activity that take place in old age during the memory processing.Brain Changes with AgeChanges that take place in the brain in old age are facilitated by multiple factors. The effects that happen in the brain function are tied to the certain morphological and molecular changes that are caused by the aging process. The changes in the brain vasculature increase the risk of ischemia in the elderly and stimulate the lesions that take place in the white matter. Lesions in the white matter precipitate changes in brain activity. A set of simultaneous brain changes affects its functions and ability to process memories.Genetics also plays a part in the changes in the brain activities of aging people. It has been proven that there is a genetic predisposition to brain disorders such as dementia. Changes in the levels of the neurotransmitters in the brain also affect brain activity (Garaschuk, 2017). The hormone levels change in old age, thereby contributing to brain functioning transformation. The insufficient brain activation leads to memory decline with age and an apparent decrease in the fluidity of memory tasks due to the decreased recruitment of the neurotransmitter effects and the hormonal influences that are associated with normal brain activity (Garaschuk, 2017). Therefore, the changes in brain activity are precipitated by a host of interconnected factors.The neurotransmitters that are most closely tied to the aging process in the brain are dopamine andserotonin. The dopamine levels have been found to decrease by about 10%, which initiates resulting changes in cognitive functions and motor activity (Johnson, 2010). The performance of the individual becomes hampered as the decline in the dopamine levels deteriorate. The decrease in the dopaminergic activity is not only linked to the levels of dopamine in the brain but also to the reduction of synapses and receptors that bind dopamine in the brain. The decline in the dopaminergic pathways that connec t the striatum and the frontal cortex are affected and this precipitates cognitive impairments. The serotonin levels also decrease with age and this is implicated in the changes in the regulatory mechanisms of the neurogenesis of the elderly brain. Such transformations result in brain activity dysregulation which affects the formation of the memories by an individual.Using neuroimaging techniques, psychologists have established that the decline in brain activity in old age is not uniform. The recent studies have refuted that there must be the same level of decline of brain activity across the board and have developed a model that defines the specific rates of mental decline in old age (Tatti, Rossi, Innocenti, Rossi Santarnecchi, 2016). This model shows that the changes in brain activity are very multifaceted and vary widely in the different individuals. An observation has also been made that the rate of these changes is reflective of the youthful activities of the individual. Corr esponding evidence points to the fact that the elderly sensitivities have correlated particularly to the individual (Garaschuk, 2017). Hence, the rates of mental and cognitive changes vary and memory processing functions retention also depends on individual predisposition.Changes in Memory ActivityMost common brain activities that are affected by age include memory and attention. The age-related changes in attention and memory are not uniform, but a consistent pattern of decline is observed in the cognition associated with these brain activities. The loss in the attention span and perceptive abilities of the individual is attributable to a great degree to the significant age-related loss of sensorial capacity (Tatti et al. 2016). Deficits in the sensory capacities translate to deficits in the processing stream of the information which is marked by a decline in attendance. The fundamental impairment of this cognitive awareness results in failure to perform certain complex tasks relat ed to the memory and recall and failure to sustain protracted attentive skills. The impact on memory follows rapidly, which is widespread and more notable, and forms up the bulk of the considerable evidence that points to brain changes in old age. Therefore, memory loss is usually an early marker of age-related cognitive impairment.Memory function as a cognitive activity can be categorized into several sections. Memory can be divided into episodic, semantic, procedural, and working memory. The first modality of episodic memory is more important when it comes to age-related changes in brain activity. This refers to memory formation where the image is stored with a mental tag to the memory attached to it with respect to the circumstances in which the memory was formed. Episodic memory majorly deals with experiences formed by an individual in the past. For example, an important meeting that an individual attended last year may form an episodic memory. This section of memory is distinct ly a human trait and is accounted as the most developed type of memories, and it is also the most highly susceptible to changes when the brain is damaged or in old age. Analysis of the different sections of me...

Essay on Ayer, A.J. Freedom and Necessity. - 972 Words

Philosophy 1301. 1002 Ayer, A.J. â€Å"Freedom and Necessity.† In the following paper I will talk about A.J. Ayer’s â€Å"Freedom and Necessity,† and I will explain the dilemma of determinism and Ayer’s compatibilist solution to it. I will explain some of the examples Ayer uses to explain the difference between cause and being constrained, and how both affect one’s free will. I will also discuss on why Ayer’s compatibilism solution to the dilemma is the best solution so far. According to A.J. Ayer, the problem of free will is the result from the conflict of two different assumptions, which are men acting freely while being morally responsible for their actions, and that human behavior comes from causal laws. Ayer begins by attacking the†¦show more content†¦No longer is this freedom vs. cause, but instead it is now viewed as caused vs. constrained. Caused is certain conditions obtain and something happens. Constrained is certain conditions obtain and something is compelled or forced to happen. Ayer us es an example of a common thief and a kleptomaniac to illustrate his point. He states that a thief makes his own decisions when stealing. The thief can stop himself from doing such crime and choose not to steal. The thief is then faced to be dealing with cause where freewill and moral responsibility apply. While a kleptomaniac suffers from such disease in which he has no choice when it comes to stealing. He is then faced to deal with constrained where freewill and moral responsibility do not apply. Both of these take place while containing determinism. So cause is part of freewill and not the opposite. There are objections that arrises to Ayer’s compatibilist solution. One is the invisible chains of causation objection. It states that all of our actions are constrained by causal laws. Ayer’s response to it is that the causes in both cases of the thief and the kleptomaniac are different. One is constrained while the other is entirely based on caused. Another objection is the all causes necessitate equally objection. It states: â€Å"For why should we distinguish, with regard to a persons freedom, between the operations of one sort of cause and those of another? Do not all causes equallyShow MoreRelated Free Will and Determinism of Ayer and Holbach Essay1811 Words   |  8 PagesDeterminism of Ayer and Holbach In respect to the arguments of Ayer and Holbach, the dilemma of determinism and its compatibility with that of free will are found to be in question. Holbach makes a strong case for hard determinism in his System of Nature, in which he defines determinism to be a doctrine that everything and most importantly human actions are caused, and it follows that we are not free and therefore haven’t any moral responsibility in regard to our actions. For Ayer, a compatibilistRead MoreCausal Determinism Threatens This Principal904 Words   |  4 Pagescausally determined, and although one thought one was acting out of free will, one is not. There is no definite proof to show that one’s choices are made freely. As A.J. Ayer stated in his essay, Freedom and Necessity, â€Å"†¦but from the fact that a man is unaware of the causes of his action, it does not follow that no such causes exist† (Ayer 272).

In Human Freedom and the Self, Roderick M. Chisholm takes the libertarian stance which is contiguous with the doctrine of incompatibility.

Ayer, similarly denied that moral assessments are factual descriptions. For example, although the statement â€Å"it is good to donate to charity† may on the surface look as though it is a factual description about charity, it is not. Instead, a moral utterance

Principles of Health Care Quality Improvement

Question: Describe about the Principles of Health Care Quality Improvement. Answer: Tonsillectomy is one of the most frequently performed surgeries in children but an accurate determination of its indications demands broad research of the childs medical history, evaluation of vital information related to the surgery, and consideration of post-surgical complications (1). As a parent of a 3 years old one should look out for the indications for tonsillectomy. A wait-and-see approach can be considered for the child who suffers from few throat infections. But for severe recurrent tonsillitis talking with the doctor about the potential benefits of operation for the child as well as the expenses and dangers of the surgery is essential. For children with recurrent tonsillitis, tonsillectomy can significantly mend the quality of life. Enlarged tonsils can cause clogged upper air-passage and breathing difficulties. Surgery can help relieve these problems (1). As a parent, it is emotionally and physically draining to see a 3-year-old child in such pain. A common parameter for tonsillectomy is at least three documented episodes in each of the previous three years or five documented occurrences in each of the past two years or seven documented incidence of a throat infection in the former year with a fever higher than 100.9F. Physicians usually recommend surgery to eliminate tonsils when a child has recurrent infections of the tonsils that are triggering severe complications or are disturbing a child's quality of life. A decision about surgery should be made with the otolaryngologist and based on the child's health and well-being (2). For taking the verdict of tonsillectomy for a 3-year-old some of the following serious medical problems should be considered: Tonsillitis that persists longer than 3 months regardless of medicines Congested airways which can causesleep apnea Ache in swallowing Tonsils that bleed worryingly (3) In addition to the above conditions, a documentation of recurrent tonsillitis can be very useful to decide the need for tonsillectomy. Documentation for recurrent tonsillitis comprises the manifestation of a sore throat and outcomes from a doctors analysis of fever, tonsil size, tonsillar or pharyngeal erythema, cervical adenopathy, tonsillar exudate, microbiological examination results (positive culture for group A -haemolytic streptococcus) etc. Additional documentation includes absences from daycare, tiredness and spread of infection within the family (3). Both harms and benefits of the surgery should be considered before the decision is made. The two main preoperative risk factors are disordered breathing during sleep and coagulopathies. But with the help of modern medical science, these jeopardise can be easily overcome. The stated rates of postoperative haemorrhage needing blood transfusion diverge from 0% to 2.3%. Demises due to postoperative haemorrhage are not scientifically documented on an international level, and any data that have been published till now on this matter are mainly hypothetical (2). Evidence advises that the most frequently and severely affected children have decent improvement with tonsillectomy and a notable improvement in the quality of life. After surgery, the child may experience tiredness for quite a few days and then gradually becomes more energetic. The child should be capable of going back to daycare or school within 1-2 weeks and return to complete doings in 2-3 weeks (4). The decision of tonsillectomy for a toddler should be made considering the above facts. References Stuck BA, Windfuhr JP, Genzwrker H, Schroten H, Tenenbaum T, Gtte K. Die Tonsillectomy in children.
