Abstract
After the publication of this article, the authors noticed the following errors in the paper: the ages of two of the cases were reported wrongly. The correct age of patient #7 should be 42 instead of 52 and the correct age of patient #8 should be 42 instead of 52 (Table 1). The corrected mean age of the 12 patients with intracerebral hemorrhage becomes 52 (s.d. 8) years (instead of 53 (s.d. 7)). The error does not influence the conclusion of this study.
