Neurocognitive and Neuroanatomical Studies in Young Children With Type 1 Diabetes Mellitus

BROCHURE: Name of Study: Neuropsychological and Neuroanatomical Studies in Young Children Study Directors: Tandy Aye, MD; Bruce Buckingham, MD; Darrell Wilson, MD About the Study: This study is being conducted to see if Type 1 diabetes mellitus has any affect on learning, behavior and development in young children. Fifty to 60 children between the ages of 3 to less than 10 years with Type 1 diabetes mellitus will have neuropsychological testing and a nonsedated MRI scan of the head performed. The study will compare the results from those with diabetes to a control group of 20-30 children between the ages of 3 to less than 10 years without Type 1 diabetes mellitus. The control subjects will have neuropsychological testing and a nonsedated MRI scan of the head performed as well. All subjects maybe asked to repeat the neuropsychological testing and nonsedated MRI scan of the head 24 months later. 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 their doctors and bring their meter(s) for downloading to each visit. The child should also tell his/her doctor about the frequency of severe low and high blood glucose values to his/er doctor as routinely asked. 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 may have the neuropsychological testing and MRI scan repeated 24 months from time of the initial testing and scan. Inclusion Criteria: To take part in the study, the child must meet the following inclusion criteria: Be between the ages of 3 to 10 years. Have been diagnosed with type 1 diabetes for at least 6 months. Do not have plans to move out of the area within the next 36 months. Exclusion Criteria: A history of head trauma with any loss of consciousness cystic fibrosis prematurity (born less than 30 weeks of gestation) significant developmental delay (lack of single word speech or ability to walk independently by 18 months of age) neurologic disease independent of diabetes (eg seizure disorder or medical contraindication to MRI procedure (eg metal appliances such as braces). Compensation: There will be no cost to the subjects to participate in this research study. Participants will be compensated for their time.
