Abstract

Abstract : Preeclampsia increases a woman's risk of stroke and leads to short-term cognitive complaints. Our objective was to assess the impact of preeclampsia on long-term cognitive performance. This is a retrospective cohort study using data from the Coronary Artery Risk Development in Young Adults cohort of healthy individuals (18–30 years) recruited from the general population in 3 cities in the United States, followed for 25 years (1985–2010). Psychomotor speed (Digit Symbol Substitution Test), executive function (Stroop Test), and memory (Rey Auditory Verbal Learning Test) were contrasted between women with and without preeclampsia using multivariate linear regression. We included 568 parous women (193 with preeclampsia and 375 with normotensive pregnancy) without baseline neurological disease or depression matched according to delivery period. Approximately 18 years after delivery, preeclamptic women scored significantly lower on Digit Symbol Substitution Test than women with normotensive pregnancy (73.21±14.79 versus 75.87±15.22; P =0.047) and on the third trial of Stroop Test (correct answers: 38.85±3.62 versus 39.42±1.87; P =0.014; completion time: 44.02±10.48 versus 41.62±10.61 seconds; P =0.01), but there were no differences in Rey Auditory Verbal Learning Test. These differences were attenuated after adjustment for age, body mass index, hypertension, education, and depression. Similar differences in neurocognitive scores were noted between women with other hypertensive disorders of pregnancy and normotensive pregnancy. Hypertension in pregnancy does not seem to be independently associated with neurocognitive impairment later in life. Abstract : Supplemental Digital Content is available in the text.
