Scientists in Singapore have found four proteins in the blood that are linked to damage in the brain’s blood vessels. This discovery may help doctors in the future to find people who need more checks for brain diseases. The research team tested blood from 518 Singaporean adults who visited a memory clinic and used brain scans and thinking tests to look for signs of vessel damage.

The most important reason for this study was to see if certain levels of blood proteins are connected to cerebrovascular disease. This condition means the blood vessels that bring blood to the brain are damaged. It can lead to serious health problems like strokes, memory loss, or dementia.

The main result is that these blood proteins were related to worse damage in the brain and more problems with memory and thinking. However, this does not yet mean doctors can use a blood test to check for brain disease. Scientists say that more research is needed before this can be used in everyday medicine.
