In the article entitled “Cerebral Infarcts and Cognitive Performance: Importance of Location and Number of Infarcts” by Saczynski et al,1 the authors would like to alter a sentence under the “Materials and Methods” section. In the second paragraph of the “MRI Scanning and Reading Protocol” subheading, the sentence “Subcortical infarct-like lesions were defined as parenchymal defects not extending into the cortex that are surrounded by an area of high signal intensity on FLAIR images with a minimal size diameter of 3 mm” should list “4 mm” rather than “3 mm” as the diameter. The authors regret this error.
