The original version of this article  unfortunately contained a typographical error. The 'Alzheimer's Disease Neuroimaging Initiative' was erroneously included as 'Alzheimer's Disease Neuroimaging Initative' in the author list of the article. Furthermore, the funders, Donor's Cure and Chatbooks were inadvertently left out of the 'Funding' section. The revised 'Funding' section should read: This work was supported by National Institute on Aging (R01AG042611 and RF1AG054052 to JSKK; R01AG032990, RFAG051504 to NET; U01AG046139 to NET, SGY, TEG, NDP; AG046374 to CMK; U01AG052411 to AMG; RO1AG18712 to RM, R01AG11380); National Institute of Neurological Disorders and Stroke (R01NS080820 to NET); Mayo Clinic Center for Individualized Medicine, Donor's Cure, and Chatbooks. This work was supported by access to equipment made possible by the Hope Center for Neurological Disorders, and the Departments of Neurology and Psychiatry at Washington University School of Medicine. The correct author group name has been included in the author list of this 'Correction' and revised in the original article. The omitted acknowledgement of the funders, Donor's Cure and Chatbooks has also been included in the original article.
