Neurologists at Harvard Medical School have found that migraines diagnosed before pregnancy are associated with poor outcomes during childbearing. Results of the study published in the journal Neurology.
Migraine may be a marker of preterm labor, gestational hypertension (a type of hypertension), and preeclampsia, the researchers said. With preeclampsia, pregnant women experience a strong increase in blood pressure, in severe cases there may be shortness of breath due to disruption of red blood cells, low platelet count in the blood, impaired liver function, kidney dysfunction, edema, shortness of breath. fluid in the lungs, visual disturbances.
“All of these conditions are closely linked to maternal and infant mortality. Our results suggest that a history of migraine is an important risk factor for these complications,” he said.
The study’s authors analyzed data from 30,000 pregnancies in 19,000 nurses. The researchers looked at the outcome of pregnancy as well as migraines diagnosed by a doctor prior to pregnancy.
In conclusion, the researchers found that pre-pregnancy migraine was associated with a 17% increase in the risk of preterm birth, a 28% increase in gestational hypertension, and a 40% increase in preeclampsia compared to the migraine-free state. Migraine with aura (a condition in which a person has flashes of light and other visual disturbances) has been associated with a slightly higher risk of developing preeclampsia than migraine without aura.
