A blood test could help diagnose a devastating brain disorder that is often misdiagnosed and ends in fatality. People who inherit the abnormal gene CSF1R always develop HDLS (hereditary diffuse leukoencephalopathy with spheroids), a disorder of the brain's white matter that leads to death between 40 and 60 years…'Given this finding, we may soon have a blood test that can help doctors diagnose HDLS, and I predict we will find it is much more common than anyone could have imagined,' says Mayo study investigator, neurologist Zbigniew K. Wszolek.
