Ischaemic stroke affects white matter ‘across the whole brain’
White matter in the brain degenerates after ischaemic stroke, not only close to the focal lesion but even in the opposite hemisphere, researchers have found.
In their study comparing 104 people with ischaemic stroke with 40 age-matched healthy controls, the investigators, led by researchers from the Florey Institute of Neuroscience and Mental Health, Melbourne, measured fibre density and cross-sectional area using a novel form of MRI imaging developed at the institute.
