Study of electroencephalogram variations in pediatric migraines and tension-type headaches indicate that electroencephalogram abnormalities are particularly prevalent in migraines, especially during headache attacks (10).

What does migraine look like on EEG?

During visual aura, either slow waves, depression of background activity amplitude or normal EEG have been reported. The most definitely abnormal EEGs with unilateral or bilateral delta activity have been recorded during attacks of hemiplegic migraine, and during attacks of migraine with disturbed consciousness.

Can you see headaches on an EEG?

An EEG can show that something’s not right in the brain, but it doesn’t pinpoint the exact problem that might be causing a headache.

The whole brain shows it in generalized seizures. The other way an EEG can show abnormal results is called non-epileptiform changes. This can be a general change in the way a normal brain wave looks. It may have an abnormal frequency, height or shape. It can also be a brain wave showing up that should not.
