“…Furthermore, hypertensive PE and eclamptic women exhibit changes in EEG recordings compared to normotensive pregnant and non-pregnant females (244). PE and eclamptic women demonstrate both diffuse and focal slowing of delta and theta waves, typically localized to the occipital lobe (234, 244–247). Eclamptic women exhibit a significantly greater number of spike discharges than PE patients (234, 244–247).…”

Eclamptic women exhibit a significantly greater number of spike discharges than PE patients (234, 244–247). Collectively, these anatomical, hemodynamic, histopathological, and electrophysiological changes that result from PE are manifested in cognitive and behavioral impairments.…”

Preeclampsia and the brain: neural control of cardiovascular changes during pregnancy and neurological outcomes of preeclampsia

2016

Preeclampsia (PE) is a form of gestational hypertension that complicates ~ 5 percent of pregnancies worldwide. Over 70 percent of the fatal cases of PE are attributed to cerebral edema, intracranial hemorrhage, and eclampsia. The etiology of PE originates from abnormal remodeling of the maternal spiral arteries, creating an ischemic placenta that releases factors that drive the pathophysiology. An initial neurological outcome of PE is the absence of the autonomically regulated cardiovascular adaptations to pregnancy. PE patients exhibit sympathetic overactivation, in comparison to both normotensive pregnant and hypertensive non-pregnant females. Moreover, PE diminishes baroreceptor reflex sensitivity (BRS) beyond that observed in healthy pregnancy. The absence of the cardiovascular adaptations to pregnancy, combined with sympathovagal imbalance and a blunted BRS leads to life-threatening neurological outcomes. Behaviorally, the increased incidences of maternal depression, anxiety, and post-traumatic stress disorder (PTSD) in PE are correlated to low fetal birth weight, intrauterine growth restriction (IUGR) and premature birth. This review addresses these neurological consequences of PE that present in the gravid female both during and after the index pregnancy.

“…After screening, the remaining 50 articles for more detailed evaluation, 21 more articles were excluded because they did not describe possible changes in EEG patterns during hypertensive disorders in pregnancy. Since we wanted to include only articles describing case-control studies in our review, 21 more articles were excluded, including 6 reviews (31-36), 9 case reports (37)(38)(39)(40)(41)(42)(43)(44)(45), and 6 case series (26,(46)(47)(48)(49)(50). These articles were used only for screening the references.…”

This review describes specialized diagnostic investigations to assess ocular status in hypertensive diseases of pregnancy. Ocular assessment can aid in early detection for prompt multidisciplinary treatment, obstetric intervention and follow-up. The investigations accurately predict the possible causes of blindness in hypertensive diseases of pregnancy. The investigations include fluorescein angiography, ophthalmodynamometry, fluorophotometry, imaging modalities, OCT, ultrasonography, doppler velocimetry and blood chemistry analysis. The review includes a summary of imaging techniques and related recent developments to assess the neuro-ophthalmic aspects of the disease. The imaging modalities have been instrumental in understanding the complex neuropathophysiological mechanisms of eclamptic seizures. The importance of blood chemistry analysis in hypertensive diseases of pregnancy has been emphasized. The investigations have made a significant contribution in improving the standards of antenatal care and reducing maternal and fetal morbidity and mortality.
