Perinatal stroke is a generic term that encompasses distinct disorders which differ either from the point of view of causality, timing or mode of onset. The overall prevalence at term is around 20-60/100000 live births, mostly term neonates. Classically, one distinguishes: - Neonatal arterial ischemic stroke (NAIS) and neonatal cerebral sinovenous thrombosis (NCSVT) that manifest soon after birth; -Presumed perinatal ischemic stroke (PPIS) that is also divided into arterial presumed stroke (APPIS) and venous stroke (PVI), and that manifests after the neonatal period, most often with motor asymmetry; and - Perinatal primary hemorrhagic stroke (PHS). Rarely, fetal strokes are diagnosed on antenatal imaging or on autopsy in stillbirths.
