New Dye Helps Early Diagnosis for Alzheimer’s Disease
A new dye has been developed and has been proven to be able to detect Alzheimer’s disease in much earlier stages.
If the dye will be approved, it will become a step in having the first tool to pinpoint the disease.
Avid Radiopharmaceuticals coloring substance, called Florbetapir, contains the tracer Florbetapir F-18 which helps in the pinpointing process.
The testing done to help determine if the dye can help early diagnosis was that patients (with six months life expectancy) underwent a brain scan using the dye. After they died, it was found out that in the autopsy the dye are sticking to the right clumps of a protein called beta amyloid. Beta amyloid is postulated to be a fundamental cause of the disease.
Currently, Alzheimer’s disease can only be confirmed via autopsy. Doctors today only use memory tests, family histories, interviews with relatives and simple paper-and-pencil test as early detection procedures.
