Are migraines brain seizures? On the surface, migraines and epileptic seizures look nothing alike. Hyperactivity in brain circuits triggers the characteristic symptoms of seizures, like convulsions and loss of consciousness. A typical migraine, on the other hand, involves a throbbing headache, nausea, and sensitivity to light and sound.
What is Migralepsy? Migralepsy is defined as a seizure triggered by a migraine attack with aura: in particular, the seizure must fulfill the diagnostic criteria for a specific seizure, it has to occur in a patient suffering from migraine with aura (MA), during, or within 1 h of a migraine attack with aura (5).
Can a seizure mimic a migraine? Migraine headaches and seizures share many similar symptoms and often a person with one disorder will experience the other. Seizure auras have many of the same symptoms as migraine auras. Many people who suffer seizures have severe headaches after their seizures because they are misdiagnosed as migraines.
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).
