The study found that women with preeclampsia complicated by pulmonary edema and especially eclampsia experienced impaired cognitive function after the onset of disease, compared to women with normotensive pregnancies. However, this impairment was not present before the onset of the disease. Women with preeclampsia without severe features did not show impaired cognitive function.
Introduction We aimed to assess cognitive function in women with preeclampsia stratified by severity, before and after onset of disease. Material and methods Prospective study performed at a referral hospital in Cape Town, South Africa. Pregnant women between 20 and 42 weeks of gestation with eclampsia, pulmonary edema and preeclampsia without severe features, and a normotensive pregnancy were approached. Women were included at diagnosis of preeclampsia or at admission for delivery (women with normotensive pregnancies). Two cognitive assessments, the Cognitive Failure Questionnaire to assess the cognitive function subjectively before inclusion in the study, and Montreal Cognitive Assessment to assess the current cognitive function objectively before discharge from the hospital after delivery, were performed. Results We included 61 women with eclampsia, 28 with preeclampsia complicated by pulmonary edema, 38 with preeclampsia without severe features, and 26 with normotensive pregnancies. There was no difference in cognitive function from early pregnancy between groups. Women with eclampsia and preeclampsia complicated by pulmonary edema scored lower on the Montreal Cognitive Assessment at time of discharge compared with women with normotensive pregnancies. The results were attenuated in pulmonary edema after adjustment for confounders. Conclusions Women with preeclampsia complicated by pulmonary edema and in particular eclampsia had impaired cognitive function after onset of disease compared with women with normotensive pregnancies. The impairment did not seem to be present before onset of disease. Women with preeclampsia without severe features did not have impaired cognitive function.
