Diabetic Ketoacidosis and Its Impact on the Brain
8. november 2019 opdateret af: Tandy Aye, Stanford University
Diabetic Ketoacidosis and Its Impact on Neurocognition
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.

Detaljeret beskrivelse
Participant Schedule:
- One visit for 3-4 hours at the Stanford Medical Center to complete neuropsychological testing and to become familiar with the MRI scanner.
- Subjects who need to become more familiar with the MRI scanning process will view a video tape at home.
- One visit for 1-2 hours at Stanford Medical Center to have the MRI scan of the head completed.
- 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.
- Subjects may have the complete neuropsychological testing and MRI scan repeated 15 months from time of enrollment.
