Yeah, it comes from lack of oxygen to the brain and it can bring on seizures and headaches. Its happened to me quite a few times. Drinking lots of water and fresh air can help.

I rarely get headaches. But I have experienced light headed , and if I got up to soon I would loose balance. I learn from that to relax a little until the light healed feeling goes away

Yes I have had them both before and after a seizure. Not only do.they happen immediately before or after, but I have had headaches with seizures related to them.
But if I have a dizziness beginning after the headaches, then I know to get to a safe place (if I have time). For me they’re two primary symptoms of my aura, which is a partial temporal seizure. Hope I helped, all my best… K.

The headache and lightheadedness have been warning signs for me for partials and grand mals since the beginning. I think the headache, dizziness, and feeling of motion when you’re sitting still, are all considered signs of a partial temporal lobe seizure, as well. Later on, when I would go into generalized seizures, I don’t think my brain has time to warn me. So yes, I have had similar experiences.

I have headaches all day everyday. Migraines come sometimes before a seizure but mostly after. I recently went through a 3 day and night Video EEG in the hospital. My Neuro said that even my smaller headaches are not a regular headache. They are small Migraines that constantly continue 24/7. With that said and to answer your question, Yes I have headaches and sometimes lightheaded before a seizure, but it isn’t consistent with me. I say that because I constantly have migraines.
