Biomarkers may help doctors screen:

Scientists in America say they are an important step towards the possibility of a test to help in early diagnosis of Alzheimer's disease took to build. A group involved in research on diseases with an important discovery that the presence of biomarkers in cerebrospinal fluid, which surrounds the spinal cord involved.

According to a report of the independent newspaper The scientists say that the existence of three specific biomarkers in cerebrospinal fluid would allow them to having Alzheimer's disease predict with 90 percent accuracy. The study found that the three biomarkers present in nine out of ten people known to suffer from Alzheimer's disease. The biomarkers were found in 1 / 3 of elderly patients, although no signs of mental impairment, is believed to be in the early stages of the disease.

study was conducted in May Clinic in Jacksonville Florida and Rochester, Minnesota. These patients suffering from late-onset Alzheimer's disease control and also used in patients who do not suffer from dementia. In addition, the sample obtained from the National Cell Repository for Alzheimer's disease. A total of 1829 cases of late-onset Alzheimer's disease and 2,576 control cases were used. The findings of the report is published in Archives of Neurology in August.

Alzheimer's affects approximately 465,000 people in the UK each year and it stands as the most common cause of dementia. The disease affects the brains of patients and results in loss of brain cells. Because it is a progressive disease, Alzheimer's patients progressively worse, and as more damage occurs in the brains of the more extreme symptoms of the disease.

It is hoped that in future, this discovery of biomarkers, the way for physicians to select patients for early preventive measures to treat if developments in medicine result in the presence of neuroprotective drugs to combat Alzheimer's smooth.

Biomarkers remain an important role in helping scientists around the world in their research. The use of biomarkers in cancer research is another area, they play an important role in promoting the knowledge and support of research and screening efforts.

Biomarker research itself has continued rapidly throughout the world and learn more about how each biomarker the medical profession, the better the research industry.
