Perinatal arterial ischemic stroke (PAIS) can be an unrecognized cause of short- and long-term neurologic disability. Focal clonic seizure in the newborn period is the most common clinical presentation of PAIS. MRI is optimal in diagnosing PAIS; negative cranial ultrasound or CT does not rule out PAIS. Given the low rate of recurrence in combination with risk factors thought to be isolated to the maternal-fetal unit, anticoagulation or antiplatelet treatment is usually not recommended. The majority of newborns with PAIS do not go on to develop epilepsy, although further research is warranted in this area. Long-term morbidity, including motor, cognitive, and behavioral disabilities, can follow PAIS, necessitating early recognition, diagnosis, and therapy initiation.
