Alzheimer Disease Case Test Questions And Complete Answers.
What is Alzheimer's disease and what causes this disorder? - Answer Alzheimer's disease is a brain disease that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks. It most often presents itself with a subtle onset of memory loss, followed by slowly progressive dementia that worsens over several years. Scientists do not yet fully understand what causes Alzheimer's disease. Causes may include some mix of genetic, environmental, and lifestyle factors. These factors affect each person differently. Alzheimer's disease damages and kills brain cells. The gradual loss of brain function that characterizes Alzheimer's disease seems to be due to two main forms of nerve damage:
1. Nerve cells develop tangles (neurofibrillary tangles)
2. Protein deposits known as beta-amyloid plaques build up in the brain
What is dementia - Answer the loss of mental functions such as thinking, memory, and reasoning that is severe enough to interfere with a person's daily functioning such as paying bills. Dementia is not a disease itself, but rather a group of symptoms that are caused by various diseases or conditions. Alzheimer's disease is the most common cause of a progressive dementia.
What is mild cognitive impairment? - Answer an intermediate stage between the expected cognitive decline of normal aging and the more serious decline of dementia. It can involve problems with memory,
language, thinking and judgment that are greater than normal age-related changes. If you have mild cognitive impairment, you may be aware that your memory or mental function has "slipped". Generally these changes aren't severe enough to interfere with your day-to-day life and usual activities. Mild cognitive impairment may increase your risk of later progressing to dementia, caused by Alzheimer's disease or other neurological conditions.
Who gets Alzheimer's disease? - Answer Alzheimer's disease is mainly as result of genetics.
Risk factors for Alzheimer's disease, such as age and genetics, cannot be controlled. Other factors that may play a role in the development of the disease, such as how much a person exercises or socialize can be changed.
Lifestyle factors, such as diet and physical exercise, and long-term health conditions, like high blood pressure and diabetes, might also play a role in the risk of developing Alzheimer's disease.
