Deans' stroke musings: New CAMERA-2 Study Shows White Matter Hyperintensities in Patients With Migraine Do Not Predict Stroke or Dementia

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

New CAMERA-2 Study Shows White Matter Hyperintensities in Patients With Migraine Do Not Predict Stroke or Dementia

Well thats a relief.

A follow-up study to the CAMERA-1 (Cerebral Abnormalities in Migraine, an Epidemiological Risk Analysis) trial (2004), CAMERA-2, was performed to evaluate whether men or women with migraine had a higher incidence of brain lesions 9 years after their initial MRI. This follow-up study was published in the Journal of the American Medical Association (2012;308:1889-1897). According to this new study, white matter hyperintensities tend to accumulate over time in patients with migraine. Hyperintensities refers to bright white spots that show up on MRIs that indicate physiological changes in brain structure and in this case white matter (fiber tracts).
It is uncertain as to whether these physiological changes are relevant to current management of migraines.
The CAMERA-1 study (2004) looked at 295 men and women with migraine along with a control group that consisted of 140 age- and sex-matched patients. These patients were asked to do a follow-up scan in 2009. The purpose of the follow-up was to assess whether these individuals had an increase in brain lesions and whether their migraine frequency was linked to progression of these physiological changes or if these physiological changes were linked to any cognitive loss. Out of the 295 migraine patients that participated in the first study, 203 participated in the second along with 83 out of 140 patients in the control group.
The follow-up study found that 112 out of 145 women with migraine had an increase in white matter hyperintensities compared with 33 out of 55 women in the control group, however, the increase in hyperintensities did not effect cognition. No statistical difference was found in other MRI-measured brain parameters. This includes infratentorial (cerebellum) hyperintensities or new posterior blood vessel necrosis. No relationship was found between frequency of migraine and lesion progression. They also reported that there was no link between migraine and progression of any MRI-measured lesions in men.
