A fetal stroke could occur at any point between from fourteen weeks gestation to the onset of labor. During a fetal stroke, the blood supply to the developing brain of the fetus is disrupted, and this can result in damage. After birth, infants who have had a fetal stroke are often diagnosed with epilepsy, cerebral palsy, or learning difficulties. Doctors are still trying to understand the causes of fetal strokes, and they now believe most cases are caused by ischemic, hemorrhagic, and thrombotic injuries that occur before birth. In fact, a study of forty-seven instances of fetal stroke identified hemorrhagic lesions in more than ninety percent of cases. MRI scans are typically used to detect fetal strokes. Risk factors for a fetal stroke include alloimmune thrombocytopenia and physical trauma to the mother, such as a fall.
