  Purpose
About the Study: This research study is being conducted to see if diabetic ketoacidosis has any impact on learning, behavior and development in children with Type 1 diabetes mellitus. If there is an impact, is it transient or persistent? Sixty to 80 children between the ages of 4 to 17 years with Type 1 diabetes mellitus will have neuropsychological testing and a non-sedated MRI scan of the head performed. The investigators will compare this to a control group of 30-40 children between the ages of 4 to 17 years without Type 1 diabetes mellitus. The children with Type 1 diabetes mellitus will not have any changes made to their current diabetes regimen. The children with Type 1 diabetes mellitus should continue to check blood glucose values as required by your doctor and bring their meter(s) for downloading to each visit. The children with Type 1 diabetes mellitus should also tell your doctor about the frequency of severe low and high blood glucose values.

Further study details as provided by Tandy Aye, Stanford University:

Primary Outcome Measures:
  • Memory score on ImPACT testing [ Time Frame: 15 months ]
    The computerized electronic testing generates a standardized test score at the complete of the test. The scores will be compared from enrollment, one week, one month and at 3 months. The change in score from enrollment to one week with be the main number used for analysis


Secondary Outcome Measures:
  • White matter volume on MRI using diffusion tensor imaging [ Time Frame: 15 months ]
    Values will be calculated according to manuscript by Aye et al in Diabetes Care Sept 2012 electronically published ahead; available on line


Biospecimen Retention:   None Retained
There is no intervention. All subjects with DM and controls get neurocognitive testing and an MRI of the brain. We want to see if the scores are different but no changes in therapy will be done.

Estimated Enrollment: 120
Study Start Date: May 2011
Estimated Study Completion Date: May 2020
Estimated Primary Completion Date: May 2020 (Final data collection date for primary outcome measure)
Detailed Description:

Participant Schedule:

  1. One visit for 3-4 hours at the Stanford Medical Center to complete neuropsychological testing and to become familiar with the MRI scanner.
  2. Subjects who need to become more familiar with the MRI scanning process will view a video tape at home.
  3. One visit for 1-2 hours at Stanford Medical Center to have the MRI scan of the head completed.
  4. Subjects between 10 and 17 years of age will also be asked to complete two additional abbreviated neuropsychological tests at one week and one month from enrollment.
  5. Subjects may have the complete neuropsychological testing and MRI scan repeated 15 months from time of enrollment.

Study Population
Sixty to 80 children between the ages of 4 to 17 years with Type 1 diabetes mellitus will have neuropsychological testing and a non-sedated MRI scan of the head performed. We will compare this to a control group of 30-40 children between the ages of 4 to 17 years without Type 1 diabetes mellitus.
