Microlacunae. Coloured magnetic resonance imaging scan of the brain of a 68 year old patient showing microlacunae (small holes, green). The may be due to a cerebrovascular accident (CVA), or stroke, which causes areas of dead tissue (infarcts) as a result of interruption in blood supply from an artery. The microlacunae may also be caused by an accumulation of protein, a plaque, which kills surrounding nerve cells. Such plaques are found in Alzheimer's disease and Creutzfeldt-Jacob disease (CJD).
