Similarly, in the AIS/DM group, BDNF plasma levels were significantly more reduced at admission, in comparison with both controls and nondiabetic patients with AIS (AIS/DM: 6.83 ± 0.81 ng/mL vs. AIS/non-DM: 8.70 ± 0.73 ng/mL, p < 0.001, respectively). This evidence concerns the gene BDNF and androgen insensitivity syndrome.
