Erratum: Low cerebral blood flow velocity and risk of white matter hyperintensities (letter)

Dr. Mindach's letter was published in the June issue of The Annals of Neurology. Unfortunately, a Reply to his letter, by Dr. C. Tzourio, was not published in the issue with Dr. Mindach's letter. Dr. Tzourio's Reply appears below in its entirety. The publishers regret this oversight and thank Drs. Mindach and Tzourio for their contributions to the Journal.
