In the article entitled "Neuropathologic Correlates of Leuko-araiosis" that appeared in the October issue of the Archives (1989;46:1124-1128), errors appeared in certain values associated with mean duration of illness. On page 1126, column 2, line 21, the mean duration of illness should have been given as 9.9 years instead of 5.7 years for patients with cortical scars. Also on page 1126, column 2, line 23, the mean duration of illness should have been given as 5.7 years instead of 9.9 years for patients without cortical scars. Therefore, the sentence should have read as follows: "The presence of cortical scars in patients with AD was associated with a longer mean duration (9.9 years) of illness than was seen among the patients without scars (5.7 years, P =.028)."
