Ans. The key is B. CT brain. [basilar migraine can cause severe headache and LOC. But there occurs no neurological deficit and on recovering from unconsciousness becomes completely alert. But to diagnose basilar migraine there should at least history of two migraine attacks with aura. As here diagnostic criteria of basilar migraine is not fulfilled we can not discharge the patient without neuroimaging like CT or MRI].
