Now a simple blood test to help diagnose Alzheimer's disease

Japanese researchers have developed cheap and easy way to diagnose Alzheimer’s via simple blood test. The test requires a small amount of blood for testing.

Findings published in science journal Nature

The new method to check the buildup of a protein in the brain, which is believed to have links with the disease enables broader clinical access and efficient population screening. While the cause of Alzheimer’s, which is the most common form of dementia, is not exactly specified, but abnormal buildup of the protein amyloid-beta is said to be one of the factors that leads to its development.

Currently this is being checked through a PET scan, and examination of cerebrospinal fluid extracted from the waist by using a long needle. But these methods are costly and physically painful.

Amyloid-beta starts accumulating in the brain about 20 to 30 years before the development of Alzheimer’s and the buildup is believed to increase the risks of developing the disease in the future. This new method may be eventually used to also check the chance of getting the disease.

What is Alzheimer’s disease?

Alzheimer's disease is a type of dementia that causes problems with memory and other cognitive abilities serious enough to interfere with daily life. Medicine can temporarily slow progress of the signs but at present there is no treatment to completely cure the disease.
