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).

What kind of migraine mimics a stroke?
Hemiplegic migraine is a rare and serious type of migraine headache. Many of its symptoms mimic those common to stroke; for example, muscle weakness can be so extreme that it causes a temporary paralysis on one side of your body, which doctors call hemiplegia.
Are migraines a form of epilepsy?
Can Migraines Cause Epilepsy? One theory is that migraines could cause damage to the brain, making it epileptic. But there’s no evidence this is true. Another possibility is that migraines trigger seizures, the main symptom of epilepsy.
Are migraines like small strokes?
Migraine can sometimes be mistaken for a stroke caused by bleeding on the brain, called a subarachnoid haemorrhage (SAH), which is often characterised by a sudden, very severe headache.

Does an EEG show past seizures?
The EEG generally records brain waves between seizures, called interictal brain waves. These waves may or may not show evidence of seizure activity.
What would cause a seizure all of a sudden?
Seizures can happen for many reasons; It may be from high levels of salt or sugar in your blood; brain injury from a stroke or head injury brain problems you are born with or perhaps a brain tumor. Dementia, such as Alzheimer’s disease, high fever or illnesses or infections that hurt your brain.
