Introduction

The disease is a progressive disease which means that the disease gets worse and over time more functions are lost. The disease first attacks the memory center of the brain, causing people will forget things. This disease is common in people 65 years or older. The causes and symptoms of Alzheimer's are different than other forms of dementia.

Alzheimer's disease is a degenerative brain disease for which no cure exists. This disease slowly attacks nerve cells in all parts of the cortex of the brain and some surrounding structures, thereby deteriorating the individual capabilities of emotions, recognize errors, coordinate movement, and remember. When this advanced disease the person loses all memory and mental functioning. Nearly half of all people who are in hospitals and elderly over 85 suffer from Alzheimer's disease. This disease is the fourth leading cause of death in adults and, unless methods are developed for the prevention and treatment of Alzheimer's disease this will be even more common in the coming years. Early symptoms of Alzheimer's disease may be overlooked because they resemble signs of natural aging. These symptoms include forgetfulness, loss of concentration, unexplained weight loss and motor problems, including mild difficulty walking. In healthy individuals, similar symptoms can result from fatigue, grief or depression, illness, loss of vision or hearing, use of alcohol or certain medications, or simply the burden of having to remember too many details immediately. But when memory loss worsens, the family and friends feel that there are serious problems.

Biological factors in the brain for this disease are found twisted nerve cell fibers called tangles neurofibrilatories and sticky protein called beta amyloid. The entangled fibers are damaged microtubules, this is the support structure that permits the flow of nutrients through the neurons. In the protein known as tau is found in these tangles, and some experts believe that this defective version attracts and maintains normal tau proteins commonly help the formation of a healthy microtubule structure. The second test is a high concentration of sticky protein called beta amyloid, which forms patches called neuritic plaques. These plates are outside nerve cells surrounded by the remains of dying neurons. Beta amyloid protein itself is a larger protein called amyloid beta amyloid. And also associated with reduced levels of the neurotransmitter acetylcholine. Neurotransmitters are chemical messengers in the brain. Acetylcholine is part of the cholinergic system, essential for the processes of memory and learning, which is progressively destroyed in patients with Alzheimer's disease. Researchers have identified important proteins, including associated binding protein of retílo reticulum and AMY plates, which are in areas of the brain affected by Alzheimer's disease. ERAB endoplasmic reticulum appears that combines with amyloid beta for attracting new beta amyloid out of the cells. It also appears that high amounts of ERAB enhance the destructive power of its partner protein nerves. AMY plaques resemble both the beta amyloid, which could be detected only through highly sophisticated techniques.

A recent study is that the risk factors for Alzheimer's disease may be different in women and men. Men have a higher risk of developing Alzheimer's disease. Estrogen therapy may help protect older women. Creaneoencefalico trauma to the head can accelerate the development of Alzheimer's disease in individuals who are already susceptible to disease. Some studies have found a link between atherosclerosis, or hardening of the arteries,
