Alzheimers Risk Might Now Be Predicted Using A Blood Screening Test

By jeremyc | July 18, 2017

At present, there’s no simple, inexpensive, and effective method to identify Alzheimer’s risk. Hopefully, this might not be the case in near future. Researchers show that a simple blood test screening might accurately identify the markers of this disease, long before symptoms kick in.

The early warning signs of Alzheimer’s are confusion and memory loss. However, changes in the brain start occurring much earlier. It is noticed that a lot of neuronal loss happens in people with Alzheimer’s disease before they start experience the early symptoms.

In Alzheimer’s patients, a protein known as amyloid beta starts building up in the brain and later forms plaques, sticks to neurons, and leads to neurological damage. All of this triggers the onset of Alzheimer’s and over time make the disease worse.

That’s why, there’s an acute need of a widely-available and inexpensive screening test that can declare an individual’s risk of Alzheimer’s before the buildup of plaque happens. Currently there are two tests available, PET scanning and spinal tap. But both are far from ideal.

PET scanning is not only costly but it is also not so widely available. Spinal tap, on the other hand, is an invasive procedure. The fact that there are not many specialists who do this medical procedure is another drawback.

In this research the researchers found that blood test screening can accurately detect if accumulation of amyloid in the brain has started.
