N2 - Background: Confusional migraine is a rare type of migraine presenting as an acute confusional state. However, the mechanism of this confusional state remains unclear. Subject and methods: We examined an 11-year-old girl with confusional migraine, using electroencephalography, brain magnetic resonance imaging, cerebrovascular magnetic resonance angiography, and single-photon emission computed tomography to investigate cerebral blood flow changes. Results: Our findings revealed vessel narrowing in the left middle and posterior cerebral artery territory, indicating vasospasm and suggesting that the confusion was caused by hypoperfusion. However, abnormal increased cerebral blood flow in the left middle and posterior cerebral artery territory was observed during the non-confusional state. Conclusion: The recorded cerebral blood flow changes are similar to those associated with migraine attacks, gradually changing from abnormally low to abnormally high during the confusional and post-confusional state.
