Effects of Acute and Chronic Glycemic Control on Memory Performance in Persons with Type II Diabetes Mellitus

Memory performance was measured in 48 persons between the ages of 40 - 65 with Type II diabetes. Correlations between performance on the California Verbal Learning Test, tests of Working Memory, Priming Memory, and Prospective Memory and several predictor variables were examined. These variables included the Slosson Intelligence Test Scores, demographic variables, presence of diabetic complications, finger-stick and HbA1c measures. Subjects performed worse than the normative sample on the California Verbal Learning Test. Higher chronic and acute blood glucose tended to be associated with worse performance on the CVLT, Priming, and Working Memory. However, after the effects of intelligence, education, and sex were statistically controlled, glycemic status predicted performance on just a few memory measures. These were short-delay recall compared with recall on List A trial 5, and List B on the CVLT, and recall accuracy on digit forward of the Working Memory Test. Glucose status was unrelated to performance on a prospective memory test. Several other demographic and diabetic complication factors predicted performance beyond the contribution of intelligence. These results contrast with previous studies which found strong effects of glycemic control, but did not statistically control for the contribution of intelligence. Differential effects of diabetic status on different aspects of memory were discussed.
