Cause of Alzheimer’s Disease

Alzheimer’s disease is a form of a mental disorder that is also known as “dementia”, a brain disorder that affects and seriously impedes the brain’s ability to process rational or normal thought. This usually results in limiting the amount of daily activities that require the use of cognitive abilities of its sufferers. Alzheimer’s is a debilitating disease because it affects the part of the brain that is responsible for thought, memory, and language.

Alzheimer’s is especially one of the most disabling diseases that can affect the older population. What makes Alzheimer’s disease a very serious affliction is that it is a progressive disorder that can slowly kill the irreplaceable nerve cells in the brain. Although Alzheimer’s is detected more often among patients over 60 years old, there are some individuals as young as 50 years of age who can show signs of Alzheimer’s.

Alzheimer’s disease holds no boundaries. It can equally affect people of different cultures and is found to afflict both males and females in equal proportions. Not one particular test is known to be used for diagnosing Alzheimer’s. A variety of methods and tests are being used to diagnose 90 percent of Alzheimer’s cases. A 100 percent accuracy in diagnosing the disease can only be achieved upon autopsy to check for plaques and tangles in the sufferer’s brain.

The root cause of Alzheimer’s disease is not yet quite well understood despite the many years of research on the debilitating condition. Alzheimer’s is a complex disease that can be caused by a number of different influences.

The main cause of Alzheimer’s disease that researchers today have found out is damaged brain cells that die for unknown reasons. The cause of Alzheimer’s disease, which was first isolated by the German neurologist Dr. Alois Alzheimer, is the abnormal clumping together of brain cells. These clumps, also known as plaques, and knots or tangles which disrupt normal brain functioning, are considered as the main definitive characteristics of Alzheimer’s disease.

Alzheimer’s Disease and Its Cause

Genetics are also being studied as a possible cause of Alzheimer’s disease. Another possible cause of the disease is seen to be a slow developing viral infection that results in brain inflammation. Although the actual cause of Alzheimer’s disease may not yet be known and still in the discovery stages, there are a number of risk factors that is known to increase the likelihood of Alzheimer development.

Age is known as a risk cause of Alzheimer’s disease. As a person ages, the likelihood that he or she will develop Alzheimer’s also increases. The average age of diagnosis for Alzheimer’s is about 80 years old. Gender is also seen as involved in the development of Alzheimer’s disease, but studies for this may still be inconclusive. The reason as to why the risk is seen to be greater in women is that they tend to live longer than the men.

Hereditary tendency is being looked into as another risk cause of Alzheimer’s disease. The presence of some defective genes and genetic mutations within the same bloodlines has also been seen to increase the development of Alzheimer’s disease.

Another possible cause of Alzheimer’s disease that is being looked into is the malfunction of the immune system and protein imbalances that occur in the brain. Certain environmental factors such as the presence of aluminum in the home or workplace are also being put under investigation as a possible cause of Alzheimer’s disease.

Who are you? Alzheimer’s symptoms

From the German psychiatrist who first diagnosed the disease, Alzheimer’s is a fatal disease that has both no known cause and cure. There are treatments that help prevent the disease to develop into its complete form. Plus medications already exists which could assist patients to manage their agitation, depression, hallucinations or delusions which could manifest during the later stages of the disease.

There are a number of symptoms which help diagnose the disease. The most prominent of which is memory loss. What seems to be a simple lapse in memory could be the start of Alzheimer’s disease. Loss of memory in Alzheimer’s is manifested from the more than unusual fluctuating forgetfulness to short-term memory loss.

Later, the patient will start to forget familiar things and well-known skills. They will start to forget names, objects, and persons even those that are close to them. Alzheimer’s memory loss is often accompanied by aphasia, disorientation and disinhibition. Aside from forgetfulness and amnesia, some refer to Alzheimer’s related memory loss as memory decay, memory decline, or memory impairment (Loring, 1999).

One, however, should not conclude that all memory loss is caused by Alzheimer’s disease. There are two basic causes of memory loss, namely normal or age related memory loss and the abnormal type. It is normal that middle age and older people begin to forget a number of things. Their ability to remember is often times measured on a standardized scale.

If their memory scores fall within the designated cutoff, their memory loss is due to normal and age-related causes. Meanwhile, if they fail to pass the scores it means that their memory loss is caused by not mere age-related reasons but by abnormal, or age-inappropriate, memory disease or impairment instead. One, therefore, needs to let professional medical workers to isolate and determine if he/she got Alzheimer’s disease.

Aside from the early symptom of memory loss, Alzheimer’s disease at the early stage could also change the patient’s behavior. And as the disease develops, the patient will loose more and more control over body functions such as affecting the way the person thinks and respond. With the effects on the brain’s cognitive functions, the patient will have trouble talking, will find skilled movements troublesome to do and hard to accomplish, and will start slowing down in terms of movements.

The patient will become indecisive and will start having trouble in decision-making processes and planning stages of human activities. These losses of memory and cognitive functions are related to the frontal and temporal lobes of the brain. The two lobes are becoming disconnected from the limbic system due to the disease.

Also, part of the symptoms of Alzheimer’s is mood swings and outbursts of violence or excessive passivity. The later stages will be more horrible. People with Alzheimer’s will later on start to loose bowel movement as well as muscle control and mobility. Alzheimer’s usually develops and become fatal within approximately 710 years.

Since Dr. Alzheimer diagnosed the disease in 1901, there have been a lot of medical discoveries and tons of results from research studies and medical investigations that were found to be beneficial in preventing or delaying Alzheimer’s disease.

Studies found out that exercise helps lessen the risk of contracting the disease. Scientists have found significant findings which indicate that having high blood pressure, high cholesterol, and low levels of the vitamin folate can increase one’s risk of acquiring Alzheimer’s disease.
