Vgontzas A, et al. - Researchers here aimed at describing acute headache diagnoses in women presenting emergently in the postpartum period and at determining which factors may be associated with secondary vs primary headache. They found a secondary headache in nearly three-quarters of postpartum women who present with acute onset headache and receiving neurological consultation. Nearly half of the secondary headaches attributed to postpartum preeclampsia (PEC) or cerebrovascular headache disorders. They strongly recommended considering neuroimaging in the absence of a headache history and a clear postdural puncture headache (PDPH) description to rule out cerebrovascular etiologies of headache as well as close monitoring for signs and symptoms of preeclampsia in women presenting with acute severe postpartum headache.
