Impaired fasting blood glucose is associated to cognitive impairment and cerebral atrophy in middle-aged non-human primates
Figure 3. Relationship between fasting blood glucose and spatial memory performance. (A) Spearman correlation between fasting blood glucose levels and number of errors in all lemurs (young in grey symbols and middle-aged in black symbols). (B) Spearman correlation between fasting blood glucose levels and number of errors in middle-aged lemurs only. Horizontal and vertical dotted lines illustrate the threshold differentiating good and poor performers in spatial memory test or high and normal blood glucose levels, respectively.
