What Is The Cause Of Alzheimer's Disease?
The ultimate result of this is the reduction of efficiency of the neurotransmitter system in the brain. The catabolism of dopamine also serves as a large source of free radical generation in Alzheimer’s disease. Another possible mechanism involved in Alzheimer’s disease is the creation and accumulation of glutamate hydroxyl radical (Behl et al., 1992) and also the over production of superoxide dismutase. This leads to the accumulation of hydroxyl radical produced from the conversion of hydrogen peroxide (H2O2). A characterization of Alzheimer’s disease is by the loss of the amyloid B (beta) protein which is in the neocortex that is associated with oxidative stress and neuronal demise. The cause of the neuronal loss in patients with Alzheimer’s

    Alzheimer's disease is one of the most common causes of dementia. The term 'dementia' describes a set of symptoms, which can include memory loss, changes in mood and problems with communication and reasoning. These symptoms occur when certain diseases and conditions, including Alzheimer’s disease, damage the brain. Alzheimer's disease could be described as a physical disease affecting the brain. During the course of the disease, protein 'plaques' and 'tangles' develop in the structure of the brain, leading to the death of brain cells. People with Alzheimer's may also have a shortage of some important chemicals in their brain. These chemicals are involved with the transmission of messages within the brain.…

    B. The clinical criteria for the diagnosis of Alzheimer's disease include progressive impairment of memory loss and other cognitive functions. There are no motor, sensory, or coordination deficits early in the disease. The diagnosis cannot be determined by laboratory tests. There is no single test that proves a person has Alzheimer's. A diagnosis is made through a complete assessment that considers all possible causes, when you go to your primary doctor visit. Neuropsychological tests provide confirmatory evidence of the diagnosis of dementia and help to assess the course and response to…

    Alzheimer’s disease is characterized as a type of dementia that causes problems with memory, thinking, and behavior. It is irreversible and it slowly destroys memory and thinking skills and, eventually, the ability to perform simple tasks. Unfortunately, Alzheimer's is the sixth leading cause of death in the United States and over five million Americans are currently living with Alzheimer’s. There are many symptoms within each category of Alzheimer’s. In mild Alzheimer’s disease, where Alzheimer’s is usually diagnosed, the person presents with memory loss and other problems such as behavior changes, losing things, repeating questions, getting lost, and taking longer to complete activities of daily living. In the next category, moderate Alzheimer’s…

    Alzheimer's is a disease of the brain that causes a loss in memory. This results in dementia, loss of brain functions (thinking, remembering, and reasoning) severe enough to interfere with everyday life. When German physician, Alois Alzheimer, first described the disease in 1907, it was thought to be rare. Today, Alzheimer's disease is the most common cause of dementia, affecting 10% of people 65 years old, and nearly 50% of those age 85 or older. An estimated four million Americans have Alzheimer's. Alzheimer's disease usually begins gradually, causing a person to forget recent events and to have difficulty performing familiar tasks. How quickly the disease advances differs from person to person, causing confusion, personality and behavior changes, and impaired judgment. Communication becomes difficult for Alzheimer's patients. They struggle to find words, finish thoughts, or follow directions. Eventually, people with Alzheimer's become unable to care for themselves.…

    Alzheimer’s disease is the number one form of dementia in the United States today. The more this disease progresses the worse it gets because there is no cure for it at this time. Most people do not show signs or symptoms of this disease or even get diagnosed until about age sixty-five. There is also no known cause for this disease and mostly people want to link Alzheimer’s to being hereditary. Mr. Speed will require secondary care especially in this case because Mr. Speed is barely in the early stages of the disease. When his disease progresses even more and is in the final stages, which can be five to ten years from now, maybe sooner, he will then require tertiary care.…

    I don't believe that problems with sleep lead to Alzheimer's. My step-grandmother had it and she had no problems with sleep. My stepfather is having issues with his memory and he sleeps fine. My grandfather never had any issues with his memory until a few months before he died (no issues sleeping); he had a brain tumor. Now since I have issues with sleep and my memory (always with memory, not with sleep) you're going to tell me I'm going to/may have/get Alzheimer's? Therefore, I think it's just crazy; just like everything else, it has to do with environment, food, genetics…
