Blood Test Detects Early Alzheimer's Symptoms
Scientists have developed a simple blood test to detect early signs of Alzheimer's disease.
This test checks for certain proteins in your blood that indicate the disease.
The test is very accurate, similar to existing methods but easier and cheaper.
It can identify those with memory problems 95% of the time and is already available.
Alzheimer's disease is becoming more common, affecting millions of Americans.
Early detection through tests like these can help with early intervention and treatment.
A new blood test can accurately detect early signs of Alzheimer's disease.
The test looks at amyloid beta 42/40 and p-tau217 proteins in the blood.
It has 95% sensitivity in identifying people with memory problems.
The blood test has received FDA approval and is available.
Researchers are planning further studies on diverse groups and those with early stages.
