White matter lacunar infarction or white matter intensities are terms used to describe small vessel disease, small branches of arteries that burst. These branches are so small that they remain undetected until there are enough of them to appear significant on an MRI study. Another term is Binswanger’s disease revealing white matter damage to the brain in a diffuse manner as a result of numerous small branches that have burst and become infarcted. Recent research found brain network connectivity to be disturbed when there is SVD providing explanation of declines in cognitive function and processing speed. Networks were less dense, connection weight was lower and efficiency was significantly disrupted. Neurology Today 8-7-2014Lawrence, AJ.
