Methods
Patients with T1DM between the ages of 7 and 16 years were recruited from the pediatric endocrinology clinic at the University of California, Davis, Medical Center. The study was approved by the University of California Davis Internal Review Board, and written consent was obtained from the parents or guardians. Patients were eligible for participation if they did not have a history of attention and learning disorders (eg, disorders such as attention deficit hyperactivity disorder and dyslexia,
Results
Sixty-six children with T1DM enrolled in the study; 3 were excluded from the analyses because their pretest blood glucose concentrations were above the specified range (n = 2) or because the IQ score was more then 2 standard deviations below the mean. One additional patient was excluded because his parents elected to end participation before completion of the memory tasks. Descriptive data for the remaining 62 children who comprised the study sample are presented in the Table. None of the
Discussion
The ability to remember specific events along with information about the context in which these events occurred is a fundamental capacity, supporting mundane yet crucial abilities as well as more complex senses such as continuity of self. Our study demonstrated that this capacity is significantly reduced in children with T1DM who had DKA. The nearly identical mean HbA1c levels and frequency of high and low glucose episodes between children with and without a history of DKA suggest that these
