Old post from June 2010 that got misplaced but want to save:
The daily migraine :
“The American Headache Society is reporting new research showing that migraineurs have abnormal neural activity all the time, not just when we’re having a migraine attack. In particular, this research reports abnormally excited activity in the parts of the brain responsible for sight and vision. Some have speculated that this may be why bright lights and loud noises are the most common migraine triggers — the idea, I suppose, is that if those parts of the brain are overexcited already, then it is more likely that stimulating them even more will cause an attack.”
Yes, we have abnormally excited brains all the time, folks. Which unfortunately does not mean we will exhibit any benefits from this, like spontaneous brilliance or awesome eureka moments. Which I think is rather unfair of my brain… if it all excited, then it should at least put that activity to good use. The fact that one of those areas of the extra always excited part of for vision does not surprise me, since I am also photosensitive and have a prolonged aura to boot. Perhaps this study will lead to more specific anti-seizure meds, or perhaps we should be taking higher dosages than we once thought needed for migraines.
