If your question pertains to accessing WMH data, please note that the U.S. data is already publicly available at http://www.hcp.med.harvard.edu/ncs/ncs_data.php, but that we have no authority regarding public use of other countries’ data. To request permission to access other countries' data, you must contact the PIs of the individual WMH surveys to ask if their data has been made public or if the PI would be willing to make the data available to you. Unfortunately we are unable to provide this data.
