Interestingly, these analyses showed negative correlations between Hsp90α levels and MoCA (R = -0.355, P < 0.001), and VFT (R = -0.252, P = 0.007) scores, after adjusting for age, gender, diabetes duration, hypertension duration and HbA1c (see Table 2). This evidence concerns the gene HSP90AA1 and diabetes mellitus.
