EEG's
Wed, 02/09/2005 - 17:40"Migraines are a vascular problem, but EEGs to not pick up or make any abnormal looking waves from a headache. They don't detect ANY sort of blood flow, just electrical activity. I am a lisenced EMT/RN who has worked in an EMU for 6 years, and EEGs DO NOT pick up headaches"
Vascular problems do indeed show up on EEG, if blood flow is compromised - there are EEG changes. If there is a vascular change affecting the blood flow, the neurons are deprived of oxygenized blood - thus cannot produce normal EEG waves, normal electrical impulses. So electrical impulses DO depend on blood flow - and yes, true vascular migraines can be picked up on the EEG during an attack. Not between events unless there has been previous and permanent neuronal damage.
Mexican Fire - check out EEG during stroke and vasospasm - both are vascular condition and both have EEG changes.
Migraines are often misdiagnosed as epilepsy and vise versa.

Still a little confused...not surprising if those in the 'know' not sure...I'm interested because daughter has epilepsy and headaches-migraines run in family and sometimes I have scorchers including tunnel vision, vomiting,tingling/numbness down arms, garbled speech. Interested in the defining line here.Daughter is photosensitive which causes myoclonus and very short eye-flutter. Son is dyslexic too by the way...what a family!Any more ideas?Thanks both of you.
