Abstract
Aβ, amyloid beta, CAA, cerebral amyloid angiopathy, CT, computed tomographic scanning, IPAD, intramural periarterial drainage, ISF, interstitial fluid, MRI, magnetic resonance imaging, PVS, perivascular spaces, WMH, white matter hyperintensities.Cerebral white matter hyperintensities (WMH) observed on magnetic resonance imaging (MRI), or low attenuation on computed tomographic scanning (CT), are the most frequent brain imaging finding in patients with small vessel disease or dementia. It has been assumed that WMH are due to arteriosclerosis or blood-brain barrier breakdown, though recently it was demonstrated that WMH have distinct molecular signatures in Alzheimer's disease (AD) where markers of Wallerian degeneration are present, compared to normal ageing [1].
