WHAT ARE THE SIGNS OF A STROKE IN A CHILD? ARE THERE OTHER CONDITIONS THAT CAN PRESENT LIKE A STROKE?

Strokes are vascular events that result in a blockage of oxygen and nutrient delivery to brain cells, resulting in cell death (ischemia). Strokes are typically classified into 1 of 3 categories: (1) arterial ischemic stroke (AIS) is brain ischemia secondary to arterial occlusion; (2) hemorrhagic stroke comprises intraparencyhmal, intraventricular, and subarachnoid hemorrhages; and (3) venous stroke typically occurs in the context of cerebral venous sinus thrombosis (CVST) or cortical vein thrombosis. Arterial occlusion that spontaneously resolves can result in a transient ischemic attack, without findings of ischemia on magnetic resonance imaging (MRI) and with transient symptoms (typically < 1 hour in duration).
