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:BrainAGE in dominantly inherited Alzheimer’s disease

Date of Request:4/16/2013

Status:IP

ID:DIAN-D1305




Aim 1:Exploring the brain aging pattern in subjects with DIAN and controls (cross-sectionally & longitudinally)




Aim 2:Disentangling the age-related atrophy pattern from the disease-specific atrophy pattern in the brain (structural MRI)




Aim 3:Estimating BrainAGE scores in subjects with DIAN and controls to predict conversion to AD




Aim 4Exploring factors / variables, which affect BrainAGE

Investigator:Yen Ying Lim


Title:Relationship between BDNF Val66Met, Aβ, cognitive function and hippocampal volume in patients who are at risk of developing autosomal dominant Alzheimer’s disease

Date of Request:4/30/2013

Status:A

ID:DIAN-D1306




Aim 1:Examine the association between BDNF Val66Met, Aβ, disease classification (healthy and MCI), memory function and hippocampal volume cross-sectionally and prospectively




Aim 2:Examine whether physical activity modifies the relationship between BDNF Val66Met and Aβ-related decline in memory function and reductions in hippocampal volume




Aim 3:Examine whether changes in other areas of cognition are associated with BDNF Val66Met and Aβ




Aim 4Examine whether APOE genotype modifies the relationship between BDNF Val66Met and Aβ-related decline in memory function and reductions in hippocampal volume

Investigator:Randall Bateman


Title:Post-dural puncture headache: An analysis of the risks of experiencing headaches after a Lumbar Puncture procedure on the Dominantly Inherited Alzheimer Network (DIAN) participants

Date of Request:6/17/2013

Status:A

ID:DIAN-D1307

Investigator:Randall Bateman


Title:Clinical and cognitive measures of the DIAN cohort

Date of Request:7/12/2013

Status:A

ID:DIAN-D1308




Aim 1:Determine the longitudinal rate of clinical conversion from cognitively normal to dementia in a carefully studied population of DIAN participants including average age of onset and CDR and psychometric rate of progression.




Aim 2:Evaluate the cognitive and clinical change, including rate of change, by multifactorial analysis including age, estimated years to onset (parental age of onset), ApoE4, average familial onset, genetic risk factors and biomarkers.







Investigator:Anne Fagan
