Mean maternal and neonatal BDNF values (±SD) were lower in the GDM group compared to healthy controls (maternal: GDM 566.2 ± 443.0 (range 24.6–2184.0) pg/mL vs. healthy 664.6 ± 562.4 (range 25.7–2343.0) pg/mL; neonatal: GDM 351.7 ± 331.8 (range 1.0–1490.0) pg/mL vs. healthy 541.3 ± 463.9 (range 9.5–2802.0) pg/mL). Here, BDNF is linked to gestational diabetes.
