Headache in epilepsy usually occurs before or after a convulsive seizure and rarely presents as a headache alone. Blurred vision and headache starting on one side with nausea and vomiting are also common in migraine and need to be differentiated. It is best to do a long-range EEG, which needs to be observed during daytime wakefulness and deep sleep. Generally migraine has significant changes within the EEG during the seizure period, while epilepsy is seen with epileptiform discharges. However, headache with vision loss should also be investigated for intracranial lesions, such as tumors in the saddle area, and it is best to do a plain + enhanced cranial MRI again, in coronal, sagittal and axial positions.
