An Electroencephalographic Study of Patients With Toxaemia of Pregnancy and Controls*

Electroencephalography During Normotensive and Hypertensive Pregnancy: A Systematic Review

“…The final search resulted in 8 eligible case-control studies (25,27,28,(51)(52)(53)(54)(55), which are summarized in Table 1. These studies describe 782 pregnant women with hypertensive disease.…”

“…No information on hormonal or lactation status was given. Poidevin (25) found EEG anomalies in 15% of the normotensive pregnant women, which is not significantly different from the incidence of EEG anomalies in the general population (14%) (26).…”

“…The distinction between mild and severe PE was defined in only one report, which used the Pritchard definition (55); in another article no definition was given (25). No significant differences were found between women defined as having mild versus severe PE (25,55).…”

“…The incidence of EEG abnormalities in these women ranged from 5% (n ϭ 3) to 50% (n ϭ 7), with an average of 29% (25,27,28,51,52,54,55).…”

“…Obstetrical and Gynecological Survey with hypertension in pregnancy was described by Poidevin (25). The EEGs recorded postpartum in preeclamptic patients by Colle et al were considered to be "normal" in 29% (n ϭ 4/14), "subnormal" (not further defined) in 43% (n ϭ 6/14), and "pathological" in 29% (n ϭ 4/14) of the patients.…”
