Erratum
The authors of this study protocol [1] would like to amend it and clarify that one of the medication adherence scales, the Morisky Medication Adherence Scale 8 (MMAS-8) [2‐4], will not be used. This amendment will not cause any changes to the substantive contents of the article since the medication adherence will be assessed by the use of other measures. The Institutional Review Board of the National Center of Neurology and Psychiatry approved this change to the study protocol.
