Recent studies showcased at the Alzheimer’s Association International Conference in London indicate that blood tests for Alzheimer’s might significantly change the diagnosis approach and risk prediction for the disease.
On Tuesday, a study revealed a notable improvement in diagnostic accuracy among primary care doctors when they utilized blood test results to evaluate cognitive symptoms related to Alzheimer’s.
Another study published in JAMA on Wednesday highlighted the potential of blood tests in predicting an individual’s likelihood of developing Alzheimer’s-related cognitive impairment over periods of two, five, and ten years.
These blood tests work by identifying forms of two proteins, amyloid and tau, which are biological markers of Alzheimer’s. The promising capability of these tests could facilitate easier diagnoses and help healthy individuals assess their future risk even without current symptoms.
The primary objective is to manage Alzheimer’s in its initial stages with the ultimate aim of delaying and potentially preventing severe memory and thinking challenges.
While the tests show great potential, experts caution that questions remain about their optimal use and express some concerns regarding their accuracy.
