Are migraines and seizures related? The association between migraine and epilepsy could arise not because migraine attacks are epileptogenic (i.e., cause a permanent change in the brain to an epileptic state), but because migraine attacks may simply trigger seizures.
What does a migraine seizure feel like? The symptoms of a migraine-triggered seizure can begin with an aura, which is a migraine-associated neurological deficit. 1 An aura can involve any of a number of neurological symptoms, including visual changes, weakness of one side of the face or body, sensory changes, and difficulty speaking.
Can migraine symptoms mimic a seizure? Some symptoms of migraine aura can look like a seizure, including vision problems, nausea, and uncontrolled movements. But during a seizure, you could be confused, feel depressed or fearful, or even lose consciousness. Seizures usually last 30 seconds to 2 minutes. Migraine aura, though, can last up to an hour.
Do migraines show on EEG? In our study, according to headache types, there was a significantly high frequency of EEG abnormalities. Ten (24.4%) patients with migraines with aura had abnormal EEGs, and 12 (11.1%) patients with migraines without aura had abnormal EEGs (Figure 2).
