Norway uses blood tests to detect brain changes tied to Alzheimer

(MENAFN) Norway has begun using blood tests to detect brain changes associated with Alzheimer’s disease, marking a first for the country, according to a report by a public broadcaster on Tuesday.

The test, which is now being offered at hospitals to patients experiencing cognitive symptoms, measures the level of a protein linked to Alzheimer’s disease. Health experts say it represents a major step forward by offering a simpler and less invasive alternative to earlier diagnostic methods that relied on spinal fluid samples.

The introduction follows a large study led by Stavanger University Hospital that examined more than 11,000 blood samples from people aged 57 and older. The findings showed that around one in three Norwegians over the age of 70 have brain changes associated with Alzheimer’s, a figure that rises to more than 60% among those over 90.

Researchers and clinicians noted that the blood test could significantly improve early detection and monitoring of the disease. Plans are also underway to expand access by allowing general practitioners to order the test, which could strengthen preventive care and earlier intervention.

At the same time, Norwegian health authorities are preparing to evaluate new drugs designed to slow the progression of Alzheimer’s, including Leqembi and Kisunla. However, experts cautioned that high costs and the need for hospital-based treatment could pose challenges to widespread use.
