Subcutaneous blood flow in the temporal region (TSBF) was measured by the local 133 Xenon washout technique in 43 migraine patients; 19 were re‐examined in the course of spontaneous attacks. During attacks, TSBF was normal compared to the headache‐free state. In 13 unilateral attacks, the median ipsilateral to contralateral ratio of TSBF was 1: 1.276, (NS). During 30° passive head‐up tilt, TSBF decreased by a median of 27% during headache‐free intervals and by a median, 21% during migraine attacks. The difference between the 2 occasions was not significant. Head‐up tilt resulted in a median 4.5% increase in mean arterial blood pressure (MAP) and a median 5.3% increase in heart rate (HR) during headache‐free intervals and 3.4% and 3.2% respectively during migraine attacks. These results are evidence against a vasomotor disturbance of the extracranial tissues during attacks of migraine. The cardio‐vascular response to the orthostatic stimulus indicates a normal function of this part of the autonomic nervous system during migraine attacks.
