ABSTRACT:
A method of real-time determination of variations in effective diameter of cranial blood vessels, thereby to provide an indication of migraine activity, which includes determining the blood flow rate to the brain of a subject; determining the intracranial blood flow rate in selected blood vessels; and comparing the intracranial blood flow rate with the determined blood flow rate to the brain thereby to determine a change in the intracranial blood flow rate relative to the blood flow rate to the brain, indicating a corresponding change in the effective diameter of the preselected blood vessel.
