Introduction: Discordant findings have been reported about the change in pregnant women’s cognitive test performance. Visuo-spatial abilities, which are crucial in terrestrial/flight navigation, could be influ- enced by hormonal variations. Case report: A 32-yr-old Italian Air Force pilot underwent a 2-D Mental Rotation Task (MRT) and hormonal assess- ment in the second trimester of pregnancy and 1 yr after delivery. Her performance was compared with that of two nonpregnant groups of women: one with flying experience and the other without. Estradiol and progesterone were significantly higher in pregnancy compared with postpartum, while testosterone was almost unchanged. During preg- nancy, we observed a significant difference in the subject’s response time compared with pilots (she was slower) and nonpilots (she was faster). One year after delivery, her performance was still better than the nonpilot group and was almost the same as the pilot group. Discussion: Our data are consistent with an effect of pregnancy on visuo-spatial abil- ity that can last for some time after delivery, even with the early recovery of the hormonal levels. MRT smoothly changed in our subject, support- ing previous findings that women who are experts in flight navigation are less sensitive to hormonal fluctuations. Conclusion: In this case, visuo- spatial ability requiring effortful processing underwent variations during pregnancy and postpartum. Further studies are needed in order to con- firm our observations in a wider population.
