These latter are predominantly caused by intracranial small vessel disease (SVD), which comprises variable degrees of microvascular pathology. This may involve focal aggregates of protein deposition, cerebral amyloid angiopathy, arteriolosclerosis, collagenosis, microatheroma, and microaneurysms. Familial disorders such as cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, the most common cause of strokes, are characterized by severe SVD leading to arteriopathy and disintegration of the brain endothelium and parenchymal changes including subcortical infarcts, diffuse white matter changes, and neuronal atrophy. Microvascular pathology causes a chronic hypoxic state generated by reduced perfusion.
