Dementia Awarness Essay 1. The word dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. Dementia is caused when the brain is damaged by diseases, such as Alzheimers disease or a series of strokes. The term ‘dementia’ is often misunderstood and some people use the terms ‘senile’, ‘dementia’ and ‘Alzheimer’s’ interchangeably, thinking that they are one and the same thing. 2. Key functions of the brain that are affected by dementia. The brain, along with the spinal cord, makes up the central nervous system, and it is this that controls all of our body’s functions. The brain is made up of cells an within the brain there are billions of nerve cells that are known as neurons. These neurons communicate with each other and with other parts of the body by sending messages (impulses) via a system of nerve pathways. Chemical and electrical signals are necessary in controlling bodily functions ie language, decision-making, memory, personality, behavior, sensing and interpreting our environment, and controlling muscle movements. If the neurons and synapses of the brain become damaged by dementia they may have difficulty or be unable to carry the messages that tell the sections of the brain what to do. Depending on the area of the brain affected, this can result in changes to the way the individual thinks, or may result in physical impairments, personality and behavioral changes or the inability to perform certain functions. 3. If a person shows signs of cognitive impairment, it should not automatically be assumed that they have dementia. There are other conditions that have similar symptoms to those of dementia. Depressions is a common condition which can be triggered by lifes events and can be caused by chemical imbalances in the brain. A person who is suffereing from depression can show similarsymptoms to a person who has dementia. Depession can effect concentration, motivation and ability to manage everyday tasks. Delirium can also be mistaken as dementia, Delirium can deveopl quickly and is isually reversable. People have hallucinations, delusions, probles thinking or serve confusion. Some of the causes include dehydration, pain, low blood sugar level or a chest/urinary infection. 4. Medical model relates to clinical approach ie. how the changes occur within the brain, managing the condition with medication, etc Dementia as a clinical syndrome is characterized by global cognitive impairment, which represents a decline from previous level of functioning, and is associated with impairment in functional abilities and, in many cases, behavioral and psychiatric disturbances. 5. Social model is more about the person, how it affects individuals. The social model of care seeks to understand the emotions and behaviors of the person with dementia by placing him or her within the context of his or her social circumstances and biography. By learning about each person with dementia as an individual, with his or her own history and background, care and support can be designed to be more appropriate to individual needs. 6. People who have dementia should be view as a disability because they are not aware of requirements for living. They can forget to do the essential things that are vital. Taking medicines, hygiene and even eating are often forgotten. They can get lost or hurt and not understand what is necessary to correct a situation. Turning on the stove or water and forgetting to turn it off, locking doors, crossing streets etc, this can be dangerous even deadly. In the same way you would not think as an infant incapable of self care a person with dementia can not be either. Considering the facts that they cannot act in the manner of a responsible adult makes them disabled. 7. Dementia is not a single disease in itself, but a general term to describe symptoms such as impairments to memory, communication and thinking. Vascular dementia Injury HIV infection Reversible factors Memory loss A person with dementia may show any of the following problems, mostly due to memory loss some of which they may notice (or become frustrated with) themselves, while others may only be picked up by carers or healthcare workers as a cause for concern. 8. Mixed dementia refers to a diagnosis of two or three types occurring together. A person may show both Alzheimers disease and vascular dementia at the same time. Or the combination could be Lewy bodies and Alzheimers. There can also be a combination of all three types. Recent memory loss a sign of this might be asking the same question repeatedly, forgetting about already asking it. Difficulty completing familiar tasks for example, making a drink or cooking a meal, but forgetting and leaving it. Problems communicating difficulty with language by forgetting simple words or using the wrong ones. Disorientation with time and place, getting lost on or in a familiar street/place close to home. Poor judgment example A well person might get distracted and forget to watch a child for a little while. People with dementia, however, might forget all about the child and just leave the house for the day. Problems with abstract thinking for example, dealing with money. Misplacing things including putting them in the wrong places and forgetting about doing this. Mood changes unlike those we all have, swinging quickly through a set of moods. Personality changes becoming irritable, suspicious or fearful, for example. Loss of initiative showing less interest in starting something or going somewhere. 9. Some of the risk factors associated with dementia can be managed through lifestyle changes or appropriate medical treatments. Dementia can be due to age that means as we get older, we are more likely to develop dementia. Risk factors for cardiovascular disease (like heart disease and stroke) are also risk factors for all dementia. Some studies suggest that enjoying an active life, with lots of interests and hobbies might be beneficial. Other researchers have found that spending more time in education is associated with a lower risk. The genes we inherit from our parents only have a small effect on our risk of dementia. In very rare cases, a faulty gene can be passed down in a family that causes the disease in anyone who inherits it. Some forms of Alzheimer’s and dementia can be caused by faulty genes. 10. Alzheimers is the most prevalent. 5. 4 million possibly more have Alzheimers. 5. 2 million are over the age of 65 years old. 200,000 people under the age of 65 have Alzheimers and are considered to have early onset Alzheimers. Vascular Dementia is the second most prevalent. After that things convoluted a bit but Dementia with lewy bodies is probably third. 11. People with dementia may not necessarily always be forgetful, for example an individual with Front-temporal dementia may be less forgetful than a person suffering from Alzheimer disease. There memory may remain intact but their personality and behavior could be noticeably changed. Dementia with Lewy bodies is caused by neurodegeneration linked to abnormal structures in the brain. Here, the brain changes involve a protein called alpha-synuclei this interrupts the normal functioning and affect the persons memory. 12. Dementia can have a big impact on a person’s behaviour. People with dementia face widespread discrimination for a number of reasons. There remains significant misunderstanding about and stigma attached to dementia that manifests itself in widespread discriminatory attitudes. Because most people with dementia are over the age of 65, they can also face issues of age discrimination. People with dementia are also more at risk of discrimination and infringements of their human rights because they may not have the capacity to challenge abuses of their human rights or to report what has occurred. This means that many people with dementia and their carers face a poorer quality of life than the general population. People with dementia and those who care for them should be treated with dignity and respect, and should have access to high quality care, that is based on an assessment of personal needs and preferences.

Electrical Conductors vs Insulators Essay

Every thing in the world is differentiable on the basis of its electrical conductance. Some things are called insulators and these substances never conduct electricity. they include things such as cold air,wood and plastic. Then there are things that conduct electricity and current flows through them, they are called conductors. examples of conductors are most metals like copper and steel. Other materials that are sometimes used as conductors are silver, gold, and aluminum. Copper is still the most popular material used for wires because it is a very good conductor of electrical current and it is fairly inexpensive when compared to gold and silver. Aluminum and most other metals do not conduct electricity quite as good as copper. The electrons of different types of atoms have different degrees of freedom to move around. With some types of materials, such as metals, the outermost electrons in the atoms are so loosely bound that they chaotically move in the space between the atoms of that material by nothing more than the influence of room-temperature heat energy. Because these virtually unbound electrons are free to leave their respective atoms and float around in the space between adjacent atoms, they are often called free electrons. Also, this relative mobility of electrons within a material is known as electric conductivity. Conductivity is determined by the types of atoms in a material (the number of protons in each atom’s nucleus, determining its chemical identity) and how the atoms are linked together with one another. Materials with high electron mobility (many free electrons) are called conductors, while materials with low electron mobility (few or no free electrons) are called insulators. Some substances that conduct at high temperatures are called semi conductors. they do not conduct as good as conductors but have various uses that make them more versatile than conductors themselves. Lastly, are materials of recent times, called superconductors, that at very low temperatures, such as 230 Kelvin, can conduct freely without any resistance whatsoever. The difference comes down to nothing more than how the electrons are arranged around the nucleus. The laws of quantum physics say that there are only specific bands (or tracks) in which any electron can travel. There are some interesting facts about these bands. First of all, only a very specific number of electrons can travel in each one; once it’s full, it’s full. Second, which track an electron is in corresponds to how much energy that electron has. And third, some of the bands are closer to each other than others. Different atoms have different numbers of electrons, and how those electrons are arranged in the bands defines whether a material made of those atoms will conduct. In every atom, the electrons get as close to the nucleus as possible, since the bands that are closest to the nucleus are also the ones that require the least energy. That means that the outermost shell might not be completely filled, and thus an electron from a nearby atom can join this atom in its outermost shell. these moving electrons create an electrical current. therefore we can say that atoms with empty spaces in the outermost electron bands are conductors. the materials with no empty spaces in the outermost electron band are insulators. They do not let electrons flow very easily from one atom to another. Insulators are materials whose atoms have tightly bound electrons. These electrons are not free to roam around and be shared by neighboring atoms. However there are materials that fall in between conductors and insulators. Their conductance is in between metals and insulators. And their conductance can be modified by shining a light on them or injecting charges. They’re known as semiconductors. They are mostly made of atoms that don’t conduct electricity, but they have a handful of atoms with loose electrons. Under certain circumstances — by changing things like temperature or how much energy is injected — these loose electrons will start a flowing current. Superconductors are very different from the first three, since no material known today superconducts except at very cold temperatures. Scientists are discovering materials that do superconduct closer and closer to room temperature all the time, but no one is quite sure how that happens. However, some scientists have come up with a theory for how the very coldest superconductors work, known as the BCS theory. In such materials, at low temperatures, the atoms vibrate in a way that forces the moving electrons closer together. Normally electrons don’t like to huddle so close, since they’re all electrically negative and therefore repel each other. But in superconductors, the electrons actually achieve almost an attraction for each other. The result is that as one electron moves, it pulls the next electron along right behind it. Electrons slip from atom to atom more easily than they ever do normally. Therefore, atoms which, at the right temperature, can make electrons attract instead of repel each other are superconductors. In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Conductor† implies that the outer electrons of the atoms are loosely bound and free to move through the material. Most atoms hold on to their electrons tightly and are insulators. In copper, the valence electrons are essentially free and strongly repel each other. Any external influence which moves one of them will cause a repulsion of other electrons which propagates, â€Å"domino fashion† through the conductor. Simply stated, most metals are good electrical conductors, most nonmetals are not. Metals are also generally good heat conductors while nonmetals are not. While the normal motion of â€Å"free† electrons in a conductor is random, with no particular direction or speed, electrons can be influenced to move in a coordinated fashion through a conductive material. This uniform motion of electrons is what we call electricity, or electric current. To be more precise, it could be called dynamic electricity in contrast to static electricity, which is an unmoving accumulation of electric charge. Just like water flowing through the emptiness of a pipe, electrons are able to move within the empty space within and between the atoms of a conductor. The conductor may appear to be solid to our eyes, but any material composed of atoms is mostly empty space! The liquid-flow analogy is so fitting that the motion of electrons through a conductor is often referred to as a â€Å"flow. † With electricity, the overall effect from one end of a conductor to the other happens at the speed of light: a swift 186,000 miles per second!!! Each individual electron, though, travels through the conductor at a much slower pace. Effects on conductance: Different conductors have different levels of conductance. Silver is the best conductor, offering easier passage for electrons than any other material cited. Dirty water and concrete are also listed as conductors, but these materials are substantially less conductive than any metal. Physical dimension also impacts conductivity. For instance, if we take two strips of the same conductive material — one thin and the other thick — the thick strip will prove to be a better conductor than the thin for the same length. If we take another pair of strips — this time both with the same thickness but one shorter than the other — the shorter one will offer easier passage to electrons than the long one. Most metals become poorer conductors when heated, and better conductors when cooled.

America s A Mark For Victory - 933 Words

Ever since the dawn of mankind, many different races have cohabitated with each other in a multitude of respects. However, the rate at which the integration of societies have become a mark for triumph is based upon how each race has reacted to being different. In addressing this issue, the United States of America has sailed on the rough waters of diversity for many decades, causing the world to see the â€Å"land of the free† in a completely different light. Within these confines, African Americans and other suspected â€Å"minorities† have either unwillingly embraced the discrimination or revolted against it, creating their own culture, values, and beliefs. During a time when a war of different worlds raged on in the 1940s, Americans were caught within the crossfire of hypocrisy, fighting for equality abroad when it was not evident at home. Becoming a symbol for rebellion, the zoot-suiters of this era represented a change that would remain intact throughout much of th e racial peril in the 1960s. Insurgent groups such as these were unaware of how their past would come to influence their future, and Malcom X was the prime example of what exactly made him into the proactive civil rights movement leader he was. In The Riddle of the Zoot, Robin Kelly examines the ingenuity of the zoot-suiter and the way in which each member of this â€Å"culture† sparked their own amalgamation from the chains of segregation, without understanding the impact it would have for a race that engineered change inShow MoreRelatedThemes Of The Gospel Of Mark1609 Words   |  7 PagesBy: Charmaine Warford Winter 2015 The three central themes in the Gospel of Mark are: The Good News; Following the way; Kingdom of God.
