(ORDO NEWS) — A group of international researchers has developed a new type of blood test that can detect the brain proteins tau, characteristic of Alzheimer’s disease.
Today, doctors often use a combination of brain imaging and cell analysis to diagnose the disease. Moreover, the latter requires a lumbar or spinal puncture to collect a sample of cerebrospinal fluid.
There are also methods using MRI, but they can be expensive and not readily available.
Although existing blood tests can detect abnormal amounts of the tau protein, they are not as effective in detecting signs of neurodegeneration associated with Alzheimer’s disease.
The new development of scientists, created as a result of a study of 600 patients, can become a cheaper, safer and simpler alternative for diagnosing and monitoring the disease.
