Salt Concentration Experiment

Alzheimer’s Disease is a disease of the future. With the growing aged population, this disease, which affects primarily the elderly, will become of increasing relevance to the medical profession. Also, the high frequency of Alzheimer’s, and the high cost in labor, money, and material of caring for its victims shall put considerable burden on the society as a whole. Here, however, these issues are not going to be debated. Instead the pathology of Alzheimer’s will be reviewed to the extent it is known today.

The purpose or the significance of the experiment was to see if brine shrimp can survive in different salinities of saltwater. The experimental (alternative) hypothesis was supported, because in figure 1 it showed that there was an increase of the average (mean) of survival rate of the brine shrimp when the salinity level (in grams) increased. It was in Figure 1 and it shown that the rates had higher numbers (increased survival rates) and the lower salinities had lower survival rates. The raw data also had shown that higher numbers were in the higher salinities rather than in the lower salinities. The salt had an effect on the Brine Shrimp, is because the more the more salt they had (being a saltwater species) would lead to more surviving unlike a lower salinity which did not have enough salt to support the DV (the Brine Shrimp).

Alzheimer’s disease is the six leading cause of death in America with its major cause still unknown. Scientist understand that even before early onset symptoms appear there are communication errors between the neurons of the brain. As the disease progresses, family members often notice that their loved ones are more forgetful then normal. The disease progressively worsens until one is unable to recognized loved ones, has difficulty speaking, walking, and even swallowing. The brain of one with advanced Alzheimer’s is actually radically different from that have a healthy brain.

Alzheimer’s disease, considered the most common form of dementia, is a degenerative brain disorder which leads to loss of memory and decline of cognitive thinking. Alzheimer’s disease effects over 5 million Americans, a number which is expected to triple in the projected future, and is the sixth leading cause of death in the United States (Dougherty, R.J., et al). Majority of these affected people are sixty-five years of age or older and have what is called late-onset Alzheimer’s, whilst a smaller margin of individuals is younger than sixty-five years of age and are said to have early-onset Alzheimer’s. Alzheimer’s disease presents itself in three main stages, is caused by the degeneration of neurons and by the changes in protein composition in the brain, and despite the lack of definitive, early diagnosis or preventative treatment the disease can to a certain degree be detected and managed.

Alzheimer’s disease (AD), is a type of dementia that no one would ever want their grandmother or grandfather to suffer from, as it destroys memory and other important mental functions of its sufferer. Alzheimer's disease is currently ranked as the sixth leading cause of death in the United States. While the age 65 and older is its target age, it has consumed the lives of over 1.9 million people. The brain begins to show signs of damage in the hippocampus, the part of the brain essential in forming memories. As more neurons die, parts of the brain then begin to shrink. By the final stage of Alzheimer’s, damage is widespread, and brain tissue has shrunk significantly. The idea that Alzheimer’s disease is related to age in 1974 was introduced

Neurodegeneration in the central nervous system can lead to a wide assortment of cognitive dysfunctions as the system itself consists of the brain and the spinal cord in its entirety. In a multitude of cases, Alzheimer’s disease has led to eventual deterioration of the cerebrum, the frontal lobe in particular. The disease has, in the utmost severity, led to the loss of reasoning skills, learning ability, sensory awareness, and has even gone as far as negatively impacting emotional response.

Alzheimer Disease, the most common form of dementia (to a group of symptoms affecting the brain), is a neurological disorder affecting an individual’s memory, thinking skills, and ability to conduct simply everyday tasks. Alzheimer Disease is irreversible, and no cure has been established. Dr. Alois Alzheimer-the individual in which the disease is named after-detected Alzheimer in 1906 from a woman with abnormal clumps and tangled neurofibrillary (Castellani 2010). These characteristics of the brain are now directly associated with Alzheimer Disease. There are essentially two forms of the disease. Both experience the same symptoms, but one is early onset and the second is late onset. In early onset Alzheimer Disease, symptoms develop as early as 30 years of age. Late onset AD, the most common form, develops at sixty years of age and older. A family history of the disease does improve the individual’s probability of experiencing symptoms. The progression of this paper will consist of the medical changes caused by Alzheimer, how an individual can obtain it, and lastly prevention methods discovered throughout the years.

Alzheimer’s disease is a neurodegenerative disease that disrupts a person’s memory, thinking abilities, and behavior. This disease affects three major areas in the brain; the cerebrum, the cerebellum, and the brain stem. As the disease begins to take effect, these parts of the brain become obstructed, and the information that is supposed to be transmitted between neurons is hindered. The information that is responsible for sensory, learning, and memory progressively digress’ in productivity. Alzheimer’s disease causes nerve cell death and tissue loss all around the brain, which reduces the brain’s ability to function at a rapid pace and comprehend basic signals (“Alzheimer’s & Dementia,”n.d.). As parts of the brain begin to deteriorate, normal functions begin to drift away as well.

Alzheimer’s disease is a degenerative disease that attacks and ultimately destroys brain cells. Without these cells functioning properly, every aspect of a person’s life is adversely affected until they are no longer able to care for themselves. Despite years of research and the large amount of money that has gone into the study of this disease and its effects, there is much that remains a mystery in regards to Alzheimer’s disease. While great strides have been made towards a cause and ultimately a cure, there is much work to be done before Alzheimer’s disease will no longer be a threat.

Alzheimer’s is a disease of the brain that causes a steady decline in memory. This results in dementia, loss of intellectual functions such as thinking, remembering, and reasoning, severe enough to interfere with everyday life (Gwyther, 2000). As with all dementia’s, the rate of progression in Alzheimer’s patients varies from case to case. From the onset of symptoms, the life span of an Alzheimer’s victim can range anywhere from 3 to 20 or more years. The disease eventually leaves its victims unable to care for themselves. While a definitive diagnosis of Alzheimer’s disease is possible only through the examination of brain tissue, which is usually done at autopsy, it is important for a person suffering from

Alzheimer's disease is a progressive degenerative disease that affects the brain. It causes mental deterioration in the brain and may occur in middle or old age. Ultimately, a person with AD loses all memory and mental functioning over time. The disease slowly destroys memory and thinking skills, and eventually the ability to do simple tasks. Alzheimer’s is named after Dr. Alois Alzheimer, who noticed changes in the brain tissue of a women who had died of an unusual mental illness. She showed symptoms like memory loss, language problems and unpredictable behavior. He examined her body and found abnormal clumps (now diagnoses as amyloid plaques). These clumps are now considered one of the main features of alzheimer's

Due to consistent improvements in healthcare over the past few years the general population lives considerably longer. Consequently, there is a considerable increase in the prevalence of non communicable diseases such as Alzheimer’s disease. It is crucial to appreciate the fact that dementia is not a normal part of ageing. Nevertheless, it is mainly associated with ageing. Studies

Alzheimer’s is a disease that affects an estimated 5.2 million people worldwide (Gies, 2009). This disease process works on memory, over time increasing with age. Early symptoms are memory

The experimental group was those who have Alzheimer’s disease and the control was without one.

Alzheimer’s is a genetic disease that affects the brain. It destroys neurotransmitters and eventually shrinks the brain cells. Some symptoms include forgetfulness, confusion, changes in behavior, inability to think properly, and the most common, memory loss. It progressively gets worse over time. Most people affected by this disease are over 65 years old. Because there are no specific tests to diagnose this disease, it is based off a doctor’s judgment. Scientists have created medicines to slow Alzheimer’s down, but there is sadly no cure for this tragic illness.
