Final answer:
Pre-eclampsia is referred to as eclampsia when seizures, a serious complication, occur during pregnancy.
Step-by-step explanation:
Pre-eclampsia is called eclampsia when seizures occur. This is a serious complication of pregnancy characterized by high blood pressure and can lead to significant morbidity and mortality for both the mother and baby. The progression from pre-eclampsia is marked by the onset of seizures, which distinguishes the two conditions. Pre-eclampsia may be identified by symptoms such as increased blood pressure and proteinuria, which is the presence of abnormally high levels of protein in the urine. However, these symptoms alone do not warrant a diagnosis of eclampsia.
