Objective: To test the cognitive function of parturients in the days i
mmediately after delivery. Methods: One hundred postpartum mothers who
delivered normal full-term infants were tested on standardized neurop
sychological tests-the Wechsler Logical Memory Test and the Wechsler V
isual Reproduction Test. Their test results were compared with those o
f nonpregnant childless women, third-trimester high-risk pregnant wome
n, and fathers of newborns. Results: Postpartum women scored significa
ntly lower than nonpregnant women on both tests on the first postpartu
m day. The use of intrapartum analgesia mitigated the cognitive defici
t. High-risk pregnant women and fathers scored lower than nonpregnant
women only on the Logical Memory Test. Conclusion: Objective documenta
tion that postpartum women have transient deficits in cognitive functi
on, particularly in memory function, can guide caretakers in the desig
n of care plans for the postpartum lying-in period.
