Causes and Sysmptoms of Alzheimer's

Yet now, we don’t know what are the basic causes of Alzheimer's disease or how to control its progression. Researchers have made known some facts about Alzheimer's disease that are:

Most of the Alzheimer patients are over 60.
It affects both men and women equally.
It is not caused due to hardening of the arteries and stress.

Scientists yet not fully identify what causes AD, but it is obvious that it grows due to complex series of actions that take place in the brain over a long phase of time. It is possible that the causes of AD include living environmental, genetic, and lifestyle. Because people vary in their genetic constitute and lifestyle. These factors are important for prevention AD. Some other causes of AD are:

Family history

In some cases, there is an exact link between family history and Alzheimer's disease. Family history of Alzheimer disease puts next generation members at greater risk than someone with no family history. Though information in this area is growing, the link to genetics is not completely understood.

The external environment

One cause of Alzheimer's disease is possibly our environment or surrounding -- maybe something in the air, water or soil.

The internal environment

Alzheimer's disease possibly caused due to something inside the body. It could be a slow virus (diseases), a disproportion of chemicals or a trouble with the immune system.

Approximately people survive for 8 to 10 years after identifying AD, but this deadly disease can last for long as 15 to 20 years. General early stage symptoms of Alzheimer’s disease include confusion, instability in short-term memory, inconvenience with attention and spatial orientation, change in behaviour, language problems and unexplained frame of mind. In general, these symptoms are mild, and occurrence of the disease may not be clear. The three phases of AD are listed below, which represents the common progression of the disease.

Phase 1 (Mild):

This phase can last about 4 years. In early stage of Alzheimer’s patient tend to be less energetic and artless. They show signs of slight memory loss, mood swings, and are become slow to learn and react

Phase 2 (Moderate):

This is mainly longest phase and can last 3 to 10 years. In this stage, the Alzheimer’s sufferer is become noticeable. They can perform simple tasks alone, but may need support for complicated activities. They forget current events and their own history, and become more confused and detached from reality.

Phase 3 (Severe):

This is final phase and it may last 1 to 3 years. During this people may lose the capacity to feed him or herself, talk, identify people and control bodily functions, like swallowing and bladder control. Their memory deteriorates and may become nearly non-existent.
