Headache, Migraine
Conditions
Brief summary
Adenosine is a nucleoside that plays a role in both vascular and nociceptive systems, and it has been proposed that adenosine may cause headache in particularly sensitive subjects. Thus, considerable evidence implied that adenosine plays a role in migraine pathophysiology, it is still unknown if intravenous adenosine infusion provokes migraine attacks in healthy subject or in migraine patients. Furthermore, adenosine's effects on the cerebral hemodynamic remains unknown. This study aims to clarify a possible coherence between adenosine and headache/migraine. In general, the study will contribute to a greater understanding of migraine pathogenesis and possibly lead to development of specific migraine treatment.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Occurrence and change of migraine attack | Before (-10 minutes) and after infusion (+12 hours) of adenosine compared with before and after infusion of saline | Occurrence and of migraine according to international criteria |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in cerebral hemodynamic | Before (-10 minutes) and after infusion (+12 hours) of adenosine compared with before and after infusion of saline | Change on velocity of media cerebri artery. |
| Occurrence and change of headache | Before (-10 minutes) and after infusion (+12 hours) of adenosine compared with before and after infusion of saline | Occurrence of headache measured by numerical rating scale (NRS) |
| Change of diameter of the artery | Before (-10 minutes) and after infusion (+12 hours) of adenosine compared with before and after infusion of saline | Change of diameter of superficial temporal artery and radial artery. The diameter will be measured by millimeter (mm). |
