Explain the cause and treatment of Alzheimer's disease - early dementia

Explain the cause and treatment of Alzheimer's disease - early dementia




Disease called Alzheimer's disease - early dementia as German scientist Alois Alzheimer Alois Alzheimer, who discovered in 1906, and months of wounded is former U.S. President Ronald Regine. There are 4.5 million people infected with the disease in the United States of America, and the patient usually dies in a period of 8 years from the diagnosis and, in some cases, patients lived until 20 years after diagnosis.

Generate Alzheimer's disease - early dementia
The discoverer of the disease described the presence of patches or plaques plaques around brain cells, and Chapkat or blocks tangles inside brain cells and that when a microscopic examination of brain tissue, and this description is still so far as is the hallmark of this disease.

It consists of plaques from a type of protein found brain called beta amyloid beta-amyloid, while composed blocks within neurons Kckheot twisted by disfigured protein last called Tu tau, scientists have observed that these proteins increase within a particular system - where you start to co-exist regions brain responsible formemory and learning, and then the rest of the regions - as we age, but they are much more in patients with Alzheimer's, scientists did not reach specifically to the role of these proteins, but experts believe it prevents delivery of signals between nerve cells and impede the activities necessary for the continuation of the life of the cell. What is certain scientists have is that once the disease is preceded by a process of death and decomposition of long - extend for years - the brain cells that you save and retrieve information. And the death of nerve cells, shrink the brain atrophy occurs, wrinkled and lose its shape.

The photographs show the bottom sector of the brain naturally right, then the state sector Alzheimer simple and Gaza for a severe case.









The cause of Alzheimer's disease - early dementia
Scientists have not been able to identify so far clear and direct cause of the disease, but the result of ongoing research for nearly 15 years were able to identify a set of factors that could combine to eventually lead to Alzheimer's disease.


The most important of these factors:

    Aging: the most encouraging factors for the emergence of the disease, where the majority of patients infected after the age of five, sixty, and increases the chance of the disease doubled every five years subsequent to that age until it reaches 50% at age 85.
    Genetic factors: the chance occurrence of the disease than in those who suffered one of their parents or grandparents with the disease compared to natural persons.
    Diseases that affect the blood vessels in the brain.
    Serious head injuries increase the chances of infection.

Signs and symptoms of Alzheimer's disease - early dementia
In a healthy person nerve signal transmitted through proper nerve cells from one cell to another through chemical neurotransmitters.

While in Alzheimer's disease, the areas of brain tissue damage occurs and therefore some signals do not reach, causing symptoms of the disease.


The symptoms begin declining in memory with the inability to carry out the functions daily then disorder in judging things and sometimes disorientation and also some changes in speech (such as difficulty calling the floor with the ability to repeat and understand its meaning and loss increasing the ability to speak progressive aphasia. And is down on theright showing the location of memory and language centers sector in the brain that are affected by the disease compared to the sector in a healthy person to the left.

The following figure shows the synapses synapse in a healthy person and the neurotransmitter chemical acetylcholine Acetylcholine and that are affected in Alzheimer's disease in these nerve centers.



He also spoke of some changes in personal and these changes differ in speed appearance and progress from one person to another, and lose people with Alzheimer's ability to recognize places, or loved ones, can not tend to themselves as the disease continues between eight to ten years, although some patients may die at an early stage, or may live for a period of 20 years.
Usually, the doctors talk with the patient to identify and ensure that there is an imbalance in the perception cognitive impairment or changes in speech dysfunction, as well as they talk with Almlasquin the patient also interested in identifying any defect memory and problems related activity daily, such as cooking, cleaning and disposal of money and loss and confusion or cluttered mind and take care of personal matters.
This disease is most common causes of severe mental disorder injury dementia and causes severe imbalance of perception and behavior which affects the social networking and workflow capabilities.
Diagnosis of Alzheimer's disease - early dementia
Diagnosis depends on the symptoms and signs. The doctors need to some laboratory analysis.









The treatment of Alzheimer's disease - early dementia
Because you can not treat that helps slow the progression of Alzheimer's disease - early dementia, or recovery from illness definitive treatment but softens symptoms as well as to provide good service for the patient and support makes life better. While most of what is known about the disease was during the last fifteen years, however there is accelerated and expanded efforts to learn more about the disease and follow-up research to find better ways to treat and delay the appearance and prevent its development.
Exercise protects against Alzheimer's disease or dementia early
Published by The Lancet Neurology Research search urges middle-aged people to exercise for the prevention of dementia when their age. The research exercise for half an hour twice a week can lead to significant improvement. The magazine said that people in the forties can minimize the risk of dementia by half in this way. People who have been exposed to the disease could lead sport to improve the odds of non-injury have increased by 60%.
The scientists said people who are active in young and middle-aged, can enjoy healthy and more flexibility in the autumn of age. Previous studies have indicated preferred sport for the prevention of human disease dementia, but this study is the first to examine the models over a long period of time amounted to two decades. The researchers said this is important because dementia takes a long time to appear on rights.
The study was conducted on 1,500 men and a woman, wounded 200 of them with dementia at the age between 65 and 79. The scientists studied the lifestyle of people infected by more than 20 years in their lives when they were middle-aged. The researchers discovered that people who had the disease were less active and practice of sport counterparts.
