Understanding Alzheimer

It has been observed that the disease is the most common form of dementia. There is no prevention or cure for it right now but studies and tests are made. 

There are different stages and symptoms.

One of the earliest symptoms is short-term memory loss. As it progresses other cognitive abilities gradually decline. Meanwhile, there is obvious change in the sufferer's behavior and at the very last stages of the disease, the sufferer will have to depend on others for simple activities such as eating and mobility.

There are variations from one person to another. The average length of the affliction is from five to twenty years. Alzheimer eventually ends in death due to complications and infections.

Although there is more information throughout the years, the progress has been steady but smooth. For quote, the causes of the disease is still uncertain. There are some major hypotheses that seem to go around two factors: genetic or hereditary and a complex environmental interaction.

It is observed that it is primarily a disease that affects the brain, which suffers of massive atrophy affecting neurotransmitters, nerves and neurons. From these malfunctions starts  short-term memory loss, then severe injuries to memory and the loss of motor skills and other normal bodily functions.

An abnormally great deposit of proteins in the brain causes the atrophy. The real diagnosis of Alzheimer' can only really be done post mortem through an autopsy where the brain is examined and  shows a significant amount of shrinkage and a smoothening of the prevailing brain wrinkles.

However, there is no use to wait for an autopsy to find out whether one is suffering from Alzheimer's disease or not. One can have an 85 % to 90 % accuracy in the diagnosis thanks to some cognitive tests with a series of exercises and questions that are crossed checked. 
With these mental tests, it is possible to identify the disease and also helps the physician to know at which stage is the affliction.
