Scientists have discovered a new blood test to detect Alzheimer’s Disease. Using new techology, the blood test can help diagnose Alzheimer’s Disease long before any symptoms appear.
The new blood test uses synthetic molecules to identify disease-specific antibodies. This can help identify diseases such as Parkinson’s, multiple sclerosis, lupus and Alzheimer’s.
According to Dr. Dwight German, detecting Alzheimer’s at its earliest stage before any cognitive impairment starts may allow for new treatment strategies to be developed.
Alzheimer’s patients exhibit an immune system activation and neurodegeneration in several regions of the brain. Scientists think there may be antibodies that are specific to the brain disease and these may act as a biomarker.
The new blood test uses synthetic molecules that can be modified easily and produced quickly at much lower costs than other tests. The technology behind the blood test allows antibodies to be picked out and later identified.
With Alzheimer’s disease, the IgG antibody levels captured in research was approximately six times larger when compared to the control group or to patients with Parkinson’s patients. Another antibody was also identified in addition to the IgG antibody, making at least two candidate biomarkers for Alzheimer’s Disease.
Throughout the research, this blood test identified Alzheimer’s Disease with a 90 percent accuracy.
