Eclampsia an acute and life-threatening complication of pregnancy, is characterized by the appearance of tonic-clonic seizures, usually in a patient who had developed preeclampsia. (Preeclampsia and eclampsia are collectively called Hypertensive disorder of pregnancy and toxemia of pregnancy.)
A study of pregnant women's blood RNA has found specific molecular profiles that identify women at risk of pre-eclampsia. These insights can identify complications before a woman experiences symptoms.
