Alzheimer: messo a punto esame del sangue per la diagnosi precoce, accurato al 94% - Quotidiano Sanità 4 agosto - Un esame del sangue consentirà di rilevare in fase molto precoce la presenza di depositi di beta-amiloide, la proteina patologica che si accumula nel cervello dei pazienti con Alzheimer.

Is there a blood test for Alzheimer's disease?

• Risk genes: While there is a blood test for APOE-e4, the strongest risk gene for Alzheimer's, this test is mainly used in clinical trials to identify people at higher risk of developing Alzheimer's.

How do you measure Alzheimer's disease?

• Two proteins, beta-amyloid and tau, which are found in the brains of people with Alzheimer's can be measured in the fluid that surrounds the brain and spinal cord (cerebrospinal fluid). The fluid is examined for evidence of abnormal development of beta-amyloid proteins, which form plaques, and tau proteins, which form tangles.

Can a PET scan detect Alzheimer's disease?

• When PET scans showed a high amount of amyloid-beta, a protein that turns to plaques and tangles in the brains of people with Alzheimer’s, the blood test agreed 92 percent of the time. When the PET scan showed no amyloid, the blood test showed the same about 77 percent of the time.

What is a biomarker for Alzheimer's?

• A biomarker is something that can be measured to indicate the presence of a disease. Two proteins, beta-amyloid and tau, which are found in the brains of people with Alzheimer's can be measured in the fluid that surrounds the brain and spinal cord (cerebrospinal fluid).
