Evaluation of a Non-invasive Brain Compliance Measurement Device

This is a research study to understand how diabetic ketoacidosis may affect the brain and learning and to see if these changes are transient or permanent. The investigators hope to learn more about how diabetic ketoacidosis may cause changes in brain compliance (by wearing a non-invasive head band/helmet like device from Jan Medical: The Nautilus Neurowave Systemâ„¢ (NNS), learning, talking, behavior, or development. The investigators will compare those results from those with diabetes mellitus to those age and gendered matched healthy controls. Possible subjects in this study have diabetes mellitus and are between the ages of 10 to less than 17 years old OR do NOT have diabetes and are between the ages of 10 to less than 17 years old.
