One of the most hopeful stories this week came from the Alzheimer’s Association conference in Philadelphia, where scientists reported that a blood test could detect the disease with 91 percent accuracy, outperforming both primary care doctors and dementia specialists.
The test is exciting not only because of its high accuracy but also because it promises to allow patients to access treatment more quickly. Due to a shortage of specialists, it can take months for a patient with cognitive problems to receive an Alzheimer’s diagnosis, and America’s aging population is making things worse. Another study presented at the conference predicted that by 2033, patients may need to wait six years for a diagnosis.
That’s six years without access to drugs that slow the disease’s progression.
By screening out people who don’t actually have Alzheimer’s, the researchers estimate reliable blood testing would shorten the wait time to 13 months.
