Alzheimer's Disease Study

Alzheimer's Disease Study
The Alzheimer's disease as been studied by many scientists who are driven by the curiosity to know more about various risk factors that make this genetic condition seem like a mystery. The main question that researchers would want an Alzheimer's disease study to answer is "why are most cases reported at later stages in a person's life?"



It is not easy to conduct research on genetic diseases. The researcher has to collect genetic information from various families. In most cases, it is good to collect these samples from families where many members have suffered from the disease. Most researchers concentrate on late onset cases (between 60 and 70 years).



Before an Alzheimer's disease study is carried, the objective of the research should be clearly described. Typically, the first goal should be to identify the gene that is responsible for triggering production of a protein in the brain that triggers a process of degeneration of brain tissue cells.



The evaluation process should involve diagnosis and other factors which might have contributed to the worsening of the condition. In most cases, there is need to compare patients who are at the same stage of the disease. Various disease-related factors should be monitored and any similarities noted should be highlighted in readiness for an in-depth study.



In some cases, some family member might have died. The measures taken in case of this eventuality will depend on the nature of the study. Some researches require that autopsy samples be extracted and tested in order for cell lines to be established accurately. For genetic-analytical reasons, most researchers argue that in those families whereby two late onset patients are alive, three more family members should also become subjects of the research as well.



The duration of a study into the Alzheimer's disease can extend to three years or even more depending on the variables that have to be studied. Today, most researches on the disease are being conducted along ethnic and racial lines with subjects being categorized into African Americans, Hispanics, Japanese Americans, Asian Americans, the Amish and the Caucasian people.



Previous researches have shown that the Caucasian people rarely suffer from this disease. This finding continues to influence the course of future studies as far as demographic and ethnic factors are concerned. It is only qualified researchers who are authorized to carry out a research such as this one. Only they can access samples that have been extracted from subjects, accurately labeled and stored at well-equipped laboratories. One such repository in the US is National Cell Repository for Alzheimer's Disease (NCRAD).
