Search DIAN Data Resource Requests

In order to avoid the situation where two investigators study the same research question, please search our database to determine if your topic has already been studied. If you find that your topic or a related topic has already been submitted, you may wish to contact the investigator to inquire about his/her findings to determine how you might proceed. You may wish to collaborate or modify your request to avoid overlap. The results below reflect requests made since online requests have been accepted. As such, not all fields will have data as certain information, such as aims, were not collected until recently. If an entry has been assigned an ID # (e.g. DIAN-D1004), the full request has been submitted and is either approved, disapproved or in process.

Title:Frequency of movement disorders in ADAD mutation carriers

Date of Request:2/24/2016

ID:DIAN-D1608




Aim 1:The specific aim for the proposed work with the DIAN data set is to find out whether there is a difference in frequency of movement disorders in ADAD mutation carriers compared to non-carriers.




Aim 2:Additionally we aim for the examination of the kind of movement disorders respectively their particular frequency and the time of occurrence in the course of the disease.




Aim 3:Furthermore we are planning to follow an enhanced approach by querying the NACC data base for a comparison of frequency of movement disorders between patients with sporadic Alzheimer�s disease, ADAD mutation carriers and non-carriers.




Aim 4A further possibility is to additionally include patients with frontotemporal lobar degeneration for comparison of frequency of movement disorders.

Investigator:John C. Morris, MD
