lt1cruz,

Could it be that you fell and got knocked out and have amnesia of the fall? This would not be uncommon. Unattended head injuries are very hard to diagnose.

Do you have any blood sugar issues?

It could also be a TIA. Transient Ischemic Attack, otherwise known as a mini-stroke. There are unexplainable and almost impossible to diagnose or image.

I would not worry about all of the high end imaging *edit*. What they can show is still limited to those who have something worth imaging. A 6 tesla MRI would also show fine details.

I would consider an 18 to 24 lead QEEG done by a neurologist or Ph.D. who really understands QEEG waveforms. If he just relies on a computer analysis, it is not as precise at picking up minute differences.

Normal 14 lead EEG's only show chronic epilepsy, not transient problems.

My EEG shows normal but my QEEG is very indicative of brain injury dysfunction.
