Migraines are a type of headache and seizures are the main symptom of epilepsy. Migraine headaches and seizures are two different neurological problems that have similar signs, symptoms, and auras, for example, sensitivity to light (photophobia) and sound, irritability, nausea, and vomiting.
Symptoms unique to migraine and migraine auras are water retention, problems sleeping, appetite changes, and talkativeness. Symptoms unique to seizure and seizures auras are depression, a feeling of heaviness, a feeling that a seizure is approaching, and depression.
Many of the symptoms of migraine and seizures are the same, however, seizures do not cause migraines; however, people who have seizures are twice as likely to have migraines and vice-versa. People who have migraines are twice as likely to have seizures, and people with seizures are twice as likely to have migraines; however, one condition does not cause the other.
