Causes of sign and symptoms
People with Alzheimer disease also develop deposits of protein and fibre that prevent the cells from working properly. When this happens, the cells can't send the right signals to other parts of the brain. Over time, brain cells affected by Alzheimer also begin to shrink and denature.

How it affects the body body systems effected;
Central Nervous System, Alzheimer disease is principally a disease of the central nervous system, which includes the brain and spinal cord.
Digestive System- Alzheimer disease adversely affects the digestive system in several ways. Swallowing difficulties occur in people with Alzheimer’s, bowel control is also adversely affected with Alzheimer disease, faecal incontinence occurs in most people with advanced disease.
Neuromuscular System- people with advanced Alzheimer lose the ability to use their muscles in fixed ways. Patients with late-stage disease typically lose their ability to walk. The ability to maintain posture to sit safely in a chair may also be lost. The muscles become increasingly rigid as control of the neuromuscular system declines.
Physical effects;
Apraxia- impairment to perform motor skills, initial loss of skills includes the inability to perform basic daily skills, a person with Alzheimer's is unable to bathe themselves, brush their teeth or feed themselves.
Incontinence- the inability to control urine and bowel function, first episodes of incontinence are often not due to physical changes, but rather because the Alzheimer's patient is unable to locate a bathroom,…...

Physiological Changes

...------------------------------------------------- Top of Form Bottom of Form Other Free Encyclopedias » Medicine Encyclopedia » Aging Healthy - Part 3 Physiological Changes age aging differences aging age disease deterioration Ads by Google It is evident even from casual observation of physical activities, such as walking, that elderly people exhibit a deterioration of physiological processes. Moreover, the inability of athletes to continue peak performance when they reach their thirties or forties indicates that deterioration begins at a relatively young age and progresses in severity from that point on. Indeed, many studies have confirmed that most physiological processes deteriorate progressively after about thirty years of age, some functions more severely affected than others. Most of the research on age-associated physiological deterioration has utilized cross-sectional studies; that is, subjects of different ages are studied at a given point in time (e.g., the calendar year 1990). These are called cross-sectional studies because the data are collected from a cross section of the population. Since this study design provides information quickly and relatively inexpensively, it is widely used. However, because of generational factors and selective mortality, the cross-sectional design can yield erroneous information about aging. An example of how a generational factor may confound an aging study is illustrated by a hypothetical 1970 cross-sectional study......

Unit 14 Working with and Leading People

...UNIT 14: WORKING WITH AND LEADING PEOPLE Unit 14: Unit code: QCF level: Credit value: Aim Working with and Leading People M/601/0908 5 15 credits The aim of this unit is to develop the skills and knowledge needed for working with and leading others, through understanding the importance of recruiting the right people for the job. Unit abstract An organisation’s success depends very much on the people working in it, and recruiting the right people is a key factor. Organisations with effective recruitment and selection processes and practices in place are more likely to make successful staffing appointments. In competitive labour markets this is a major advantage that well-organised businesses will have over their competitors. It is important, therefore, for learners to appreciate that the processes and procedures involved in recruitment and selection to meet the organisation’s human resource needs are legal. This unit aims to develop learner knowledge and understanding of the impact of the regulatory framework on the recruitment process. There are many benefits for both the individual and the organisation of working in teams for both the individual and the organisation, most importantly that the task is carried out better and more efficiently. An understanding of team development and the leadership function is crucial when working with others. A motivated workforce is more likely to be efficient and can contribute to the long-term profitability of the business.......

Physiological Training

...Physiological Training Research In baseball we can split the year into the off-season, early pre-season, late pre-season, and in-season. To start off we need to develop foundational strength by preparing the joints, ligaments, tendons and connective tissue for more demanding training later. Baseball places uneven stresses on the body, like pitchers throw forcefully with the same arm thousands of times a year. Swinging the bat in the same direction over and over develops muscles on one side of the body more than the other side. Over time, small imbalances can create over-use injuries and the best way to prevent this is with exercises that re-develop the natural balance between left and right. The muscles of the trunk and lower back connect the upper and lower body. They support every twisting, turning, jumping, and lateral movement. They are literally the link through which all movement passes. Here are the parameters for this phase of the baseball strength-training program: Time year: Early pre-season, Duration: 4-8 weeks, Days per Week: 2-3, Sets: 2-3, Reps: 15-20 Once you’ve built a solid well-balanced foundation, the next phase of the baseball strength-training program is develop maximal strength. It serves as a foundation for muscular power and speed. The goal is to spend some time in the pre-season increasing your strength to a peak and then to convert that strength into explosive power just as the competitive season approaches. Here are the parameters for this......

Posttraumatic Stress Disorder

...Posttraumatic Stress Disorder Abstract Posttraumatic stress disorder is a common and disabling disorder that develops as a consequence of traumatic events and is characterized by distressing re-experiencing portions of the trauma, avoidance of reminders, emotional numbing and hyper-arousal. In spite of the deleterious impact of PTSD within the U.S. military, our current understanding of the human pathophysiology governing the divergent paths associated with extreme stress response the remains unabated. Given the widespread phenomenon of ‘trauma’, it begs the question of whether or not preexisting features accompany some suffers who have developed PTSD and why others may or may not face the same effect. Much research has been conducted in this arena and it seems that no one researcher has a definitive cause, much less a standardized treatment approach for PTSD sufferers.   Posttraumatic Stress Disorder Posttraumatic stress disorder (PTSD) develops as a consequence of traumatic events such as interpersonal violence, disaster, severe accidents, or other life-threatening experiences. The most common characteristics of PTSD are the re-experiencing of symptoms linked to a specific event. Patients involuntary re-experience aspects of the traumatic event in a very vivid and distressing way. This includes: flashbacks, in which the person acts or feels as if the event were recurring, nightmares, intrusive images or other sensory impressions from the event. For......

Eating Disorders

...Eating Disorders BEH/225 Ah’Nonda Bates 03/14/2014 Eating Disorders Motivation is a type of force that compels humans to portray certain behaviors in different situations. According to Kenyon (1994-2006), two types of motivational theories are the Drive Reduction Theory and the Positive Incentive Theory (Theories of Motivation). There are other theories that help explain motivation and its reasoning, but this papers focus remains on the Drive Reduction Theory and Positive Incentive Theory and their relationship to eating disorders. One can conclude that after researching the role that motivation plays with eating disorders, the disease exhibits both intrinsic and extrinsic motivation characteristics. Along with motivation, cultural and gender differences also play a role in this mental and physical disease. The Drive Reduction Theory is based on one’s physiological needs which motivate one to behave or act a certain way. This theory would explain why one eats food when hunger develops, drinks water when there is thirst, and goes to sleep when one becomes tired. The physiological need of hunger, thirst, and tiredness motivates one to act in the appropriate way. The Positive Incentive Theory proposes that both external and internal stimuli form the motivation, which one then acts upon. For example, one will eat because the sight of food causes one to become hungry. When trapped within an eating disorder, the sight of food no longer has positive......

Unit 14- P4

...plan will be illustrating the care pathway for the 2 physiological disorders and the roles of the practitioners involved. The two physiological disorders are eczema and nephrotic syndrome.  The practitioners involved in eczema are the GP and pharmacist. General Practitioners (GP): GPs look after the health of people in the local community and deal with a wide range of health problems. They take into account physical, emotional and social factors when diagnosing treatment and recommending the required treatment (AGGAS, 2013). If a GP is unable to deal with a problem themselves, the usually refer the patient to a hospital for tests, treatment, or to see a consultant with specialist knowledge (NHS Choices, 2013). For example in eczema, if the GP sees that the condition is not getting any better, or is worsening, the will refer the patient to see a dermatologist. Also, they assess, plan, implement and monitor the progress and response to treatment; and provide advice and counselling to the patients (AGGAS, 2013). Goal/Objective Completion Date Action to be taken To identify the physiological disorder Immediately 1) Baseline assessment i.e. medical history to identify clinical background and to identify and themes, patterns etc. 2) Assess baseline measurements: pulse and respiration; and observe the affected area i.e. inner elbows. 3) Confirm diagnosis and identify any potential allergies. To successful control the disorder On-going 1) Prescribe mediation i.e. 2) Refer......

...For this one I will be discussing type 2 diabetes and how different practitioners and services work together to benefit the individual. First off depending on the dire of the situation of the patient he will either be sent into the hospital or the local GP, but for this we will be going with the GP first as they are usually the first one to discuss the diabetes with the patient, first off the GP does his own examination of the blood work of the service user and if he deems that the patient does indeed have type 2 diabetes then, the results of the examination is then sent to the Doctor for a review of the tests, however they don’t always send the service user to the hospital, the GP could either send you a dietician to help make dietary changes in your life as to combat the diabetes, send the patient to a diabetes specialist care team where their main practice is the care for people who have diabetes. If they do send the patient to a doctor, then the doctor himself would have to test the patient as well, doing their own examinations making sure there are no complications, after which they will inform the patient with information on the symptoms and how to combat. After this the doctor would refer them to a podiatrist for foot care, receiving ample amounts of care on how to better take care of your feet. Due to the diabetes there is a risk of amputation of the feet if the care is not properly administered, after which they are sent to an optometrist because people who are......

Regulation of Physiological Systems by Nutrients

...REGULATION OF PHYSIOLOGICAL SYSTEMS BY NUTRIENTS Free Radicals, Antioxidants, and Nutrition Yun-Zhong Fang, Sheng Yang, and Guoyao Wu, PhD From the Department of Biochemistry and Molecular Biology, Beijing Institute of Radiation Medicine, Beijing, China; the Division of Animal Nutrition, Department of Animal Science, China Agricultural University, Beijing, China; and the Department of Animal Science and Faculty of Nutrition, Texas A&M University, College Station, Texas, USA Radiation hazards in outer space present an enormous challenge for the biological safety of astronauts. A deleterious effect of radiation is the production of reactive oxygen species, which result in damage to biomolecules (e.g., lipid, protein, amino acids, and DNA). Understanding free radical biology is necessary for designing an optimal nutritional countermeasure against space radiation–induced cytotoxicity. Free radicals (e.g., superoxide, nitric oxide, and hydroxyl radicals) and other reactive species (e.g., hydrogen peroxide, peroxynitrite, and hypochlorous acid) are produced in the body, primarily as a result of aerobic metabolism. Antioxidants (e.g., glutathione, arginine, citrulline, taurine, creatine, selenium, zinc, vitamin E, vitamin C, vitamin A, and tea polyphenols) and antioxidant enzymes (e.g., superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidases) exert synergistic actions in scavenging free radicals. There has been growing evidence over the past three......

Physiological Disorders

...Physiological Disorders Nature and diagnosis of physiological Disorders In this assignment I am going to be creating a workbook for level 3 students who study health and social care course which can help them with their studies and support I will be talking about two types of disorders which are Diabetes Mellitus Type 2 and Cerebral Vascular Accident (CVA). P1 Explain the nature of two named physiological disorders. The two types of physiological disorders I am going to be talking about are Diabetes Mellitus Type 2 and Cerebral Vascular Accident (CVA). I’m going to start by naming the physiological disorder with a definition for the both. Diabetes Mellitus Type 2: This type of physiological disorder is the most common form of diabetes. If an individual was to have this type of disorder the body wouldn’t be using insulin properly. This is called insulin resistance, because at first the pancreas would have made extra insulin which would have made up for it. Type 2 diabetes was once known as adult onset or noninsulin dependent Diabetes, this is a very chronic condition for an individual to go through. So anyone having this physiological disorder will have conditions which will affect their body metabolizes sugar. Glucose is very significant source of energy which your body need. If you have type 2 diabetes your body will either resists the effects of insulin this is a hormone which’s help regulate the movements of the sugars which go into your cells, or it doesn’t......

...Osteoporosis P1 Explanation of the condition Osteoporosis is a bone condition in which the bones become very brittle and weak, usually from a lack of vitamin D and calcium in the bones. Osteoporosis increases the risk of a bone fracture. It is a condition that affects almost 3 million people who live in the UK. Over 300,00 people who have osteoporosis are in hospital every year from fractures caused by osteoporosis. (http://www.nhs.uk/conditions/Osteoporosis/Pages/Introduction.aspx/accessed on 13th December 2015) http://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcRlYCA4Mm1Mtu_adX98fE_fTtEqOFOmKhbEwE-Jvl4kOE2Tj03cjg Causes of the physiological disorder When we are children, our bones tend to grow and repair very easily but this works but the density of our bones continues until we reach our late twenties or early thirties. Then our bone density will start to decrease. Bone loss tends to happen when women start the menopause because they stop getting their periods. When women stop getting their periods, the level of oestrogen in their body stops and people need it in their body to have healthy bones. This means women are more likely than men to develop osteoporosis or suffer from a fracture. In men, it has been known that the risk of them developing osteoporosis relates to the low levels of testosterone in their bodies which they need for healthy bones. Although bone loss is the main cause of osteoporosis, there are many other factors that increase your risk of......

Eating Disorders

...Eating Disorders Introduction to Behavioral Science BEH/225 Eating Disorders The theory of drive reduction was first proposed by Psychologist Clark Hull. His theory was based on the idea that learning only occurred if there was a physiological urge or tension that impelled the individual to behave in a manner which would satisfy the related physiological need. Unfortunately, his theory does not apply to diseases such as anorexia or bulimia. The primary drive of hunger is controlled by our brain, specifically an area known as the hypothalamus; which regulates many aspects of motivation and emotion especially hunger, thirst and sexual behavior (Coon and Mitterer 2013). With our primary hunger being controlled by our brain, it is more than likely that it is linked to a state of equilibrium which is also known as a “set point”. Our set point is the weight that we choose to maintain our bodies, and are making no effort to gain or lose weight. With that said our body tries to find a balance in regards to our food intake. Despite the amount of calories that an obese person has taken in one day, they may still feel hungry because their settling point might be too low and the reason for that is individuals train their bodies to eat a certain amount of food which than sets their “set point”. Those individuals that suffer from eating disorders such as anorexia or bulimia are typically unhappy with bodies, have low self-esteem and have such a distorted view of them. Eating......

...For the pass this assignment will describe the investigations that are carried out to enable the diagnosis of these physiological disorders. For the merit this assignment will assess possible difficulties involved in the diagnosis from their signs and symptoms. P3 There are a range of tests and diagnostic procedures is needed to diagnose dementia, but there are several that are fairly commonly used to diagnose dementia. A GP might refer a person to a specialist to help with the diagnosis. For example, they may be referred to a clinical psychologist which is a healthcare professional who specialises in the assessment and treatment of mental health conditions. Another specialist who the GP might refer someone to is a psychiatrist and they are qualified medical doctor who has further training in treating mental health conditions. The specialist may be based in a memory clinic alongside other professionals who are experts in diagnosing, caring for and advising people with dementia and their families. A specialist will usually assess the mental abilities using a special questionnaire and one that is widely used is the mini mental state examination (MMSE). This involves being asked to carry out activities such as memorising a short list of objects correctly and identifying the current day of the week, month and year. However the MMSE is not used to diagnose Alzheimer's disease, but it is useful for assessing the level of mental impairment that a person with the condition may......

Physiological Measurements

...Danielle Fuller Unit 335 CA Physiological measurements OUTCOME 1: Describe current legislation, national guidelines, organisational policies and protocols affecting work practice. When taking physiological measurements you have to take into account of the standard precautions. Bullet pointed below are some of the legalisations that relate to taking physiological measurements. Confidentiality * It is important to think about confidentiality when taking a patients physiological measurements because by law patients notes and details have to be kept private. Health & Safety Act 1974 * It is important to have knowledge of the health & safety at work act 1974, because this outlines your responsibilities as an employee, some of these include, correct use of work items provided by your employer, for example physiological measurement tools. Consent * Consents is a patient’s voluntary agreement for a health care worker to provide care. It is extremely important to have a patients consent before taking physiological measurements because a competent adult has a right under common law to grant or withhold consent. OUTCOME 2: Explain the principles of blood pressure to include: • blood pressure maintenance • differentiation between systolic and diastolic blood pressure • normal limits of blood pressure • conditions of high or low blood pressure What is a blood pressure? Blood pressure is measured in millimetres of mercury (mmHg). The reading of a blood......
