If you haven't already done so I would suggest you look at the threads on here under "what the heck was that" and "migraine or something else." Lots of helpful info. on seizures and/or depersonalization. We learned that keeping track of how you feel before, during, and after these events is very important in helping your doctor diagnose siezure or some other event.

For example: Do you remember what was happening during, before and after? Were you able to respond to others around you? Can you ask someone who was close to you during the events what you seemed like to them?

Other than that all I can say is that the fatigue seems to last a long, long time. Do a search for "mental fatigue" and "physical fatigue" on this forum.

Also keep in mind that lapses in memory are common with PCS. I've read stories about high school students who recover from their PCS and not remember much of a school year. Another person I know about didn't remember much of his entire college experience, but he could perfectly remember the Spanish he learned in high school. There are lots of suggestions on this forum about playing memory games on computers or hand helds.

All the best to you. Take care.
