What is the Alzheimers Gene?


Alzheimers disease has received a lot of attention over the last decade; much of this attention has been directed toward the existence of the Alzheimers Gene. Part of the reason behind this fact is that the cause for the disease has been difficult to pinpoint. In fact, this is because it may not have any one cause at all.

Types of Alzheimers Disease

Alzheimers Disease can be broadly categorized into two distinctive groups. These groups include late-onset Alzheimers disease and Familial Alzheimers Disease (FAD). FAD is characterized by a very early-onset and an extremely high number of family members being affected by it. Late-onset Alzheimers disease is by far the most common form.

The Alzheimers Gene

There are four chromosomes that have been shown to have something to do with the development of Alzheimers. These chromosomes are 1, 14, 19, and 21. A healthy person has a total of 46 chromosomes. These are generally 23 pairs of chromosomes; one of each pair is received from each parent.

There are many genes that have been associated with Alzheimers disease in studies, although a gene that can be labeling the Alzheimers gene does not necessarily exist. The gene that seems to be the most common indicator of late-onset Alzheimers disease is the APOE gene, located on the chromosome number 19. Specifically, when this gene shows the variant APOE4, the person with this trait is more likely to develop Alzheimers disease. This gene does not make their development of Alzheimers certain, only more likely. It seems to predispose individuals toward the disease.

In the early-onset Alzheimers disease FAD, many families that are predisposed to this disease have been shown to have an abnormality on chromosome number 21. They also seem to show more abnormalities on chromosomes 1 and 14 than other patients. This factor has lead doctors to believe that no single gene abnormality may be the cause of either type of Alzheimers disease. In fact, genes may only be a part of the overall picture of this disease.

This particular genetic discovery regarding chromosome number 21 was found interesting by many scientists because chromosome number 21 is also the chromosome involved with Down syndrome. Individuals that are diagnosed with Down syndrome have an extra copy of chromosome number 21 and they generally develop Alzheimer-like brain abnormalities as they grow older. The abnormality of chromosome 21 may be the closest thing to an Alzheimers gene that exists.

Overall, evidence suggests that there is no real Alzheimers gene, rather a large set of genes that work in conjunction with other factors that make Alzheimers disease more likely to strike.

Alzheimer Progression

When it comes to Alzheimers disease and mediacation, the treatments that can be offered in the early stages of treatment are often the most effective.

You may see your family member develop a greater difficulty in remembering names and faces. Vitamin E is thought to help with cell rejuvenation. The Mini-Mental State Examination, MMSE is often considered a standard test for people believed to have Alzheimers. Usually Alzheimers disease normally appears after a person turns 60-years-old. Limiting your alcohol intake is also very important, and this means limiting yourself to one or two drinks a day at the very most. The effects of Alzheimers disease will mostly reflect in the patients mental abilities including how the person thinks, remembers, understands as well as communicates.

However, it most commonly begins when a person is in their 50s.
In fact, a patients symptoms are indicative of their prognosis. Only you can really decide whether or not there is any advantage to you or your family in knowing that you have a greater than average possibility of developing Alzheimers at an early age. This tenth International Conference On Alzheimers Disease which was held in Madrid, Spain in July 2006 was the biggest forum focusing its attention on dementia research. In finding the right nutritional supplements for alzheimers disease, youll have to make sure you keep all of your options open.

Small bites, and slowly to give them a chance to chew and swallow without feeling rushed can make the meal time go smoothly.
In fact, this diagnosis is actually achieved by ruling out other causes of memory loss such as Parkinsons disease, minor strokes or depression. While you may not notice any changes in the person at first, by the time a person has a moderate case of Alzheimers, they will need assistance with complicated activities. With numerous topics and valuable information being shared by one another, this is a great way to get through the hard times and even get help in figuring out what you need to do in order to take care of your parents and their disease. However at the same time you do not want to overdo it. Though tests are ongoing, results may not be available for another two years, though people concerned with testing Lipitor have great hopes that these studies will indeed bear fruit. Today, there are many attractive items that comprise a broad range of jewelry bracelets that can prove helpful in emergencies and look attractive at the same time.
