yes for sure...there are some research studies about some earth changes/solar activity and their correlation with migraines with aura...


This isn't that particular article - but here is a little information

there is some good information on the glcoherence site as well -

<-- scroll down to where it says

"A number of important findings already have emerged. For example, changes in the earth’s magnetic field are associated with changes in brain and nervous system activity; performance of athletic, memory and other tasks; sensitivity in a wide range of extrasensory perception experiments; synthesis of nutrients in plants and algae; the number of reported traffic violations and accidents; mortality from heart attacks and strokes; and incidence of depression and suicide. It’s interesting to note that changes in geomagnetic conditions affect the rhythms of the heart more strongly than all the physiological functions studied so far.

There is also evidence in some cases that people’s brainwaves can synchronize with the rhythm of the electromagnetic waves generated in the earth’s ionosphere. When people say they "feel" an impending earthquake or other planetary events, such as weather changes, it is possible that they may be reacting to the actual physical signals that occur in the earth’s field prior to the event."
