Non-epileptic Seizures?

My girlfriend is 7 months pregnant and has recently been suffering from seizure-like symptoms. Sometimes she goes into catatonic states, othertimes it seems more narcoleptic. There are occasional warning signs for these events which are dizziness, confusion, hot flashes, and parasthesias. The episodes last from 5 to 10 minutes. During this time she is unresponsive; she has had nystagmus, a ping-pong effect of the eyes, and pupils dialating and contracting without stimulus; and has had intermittent ticks. Symptoms following these incidents are confusion, short-term memory loss, migranes/shooting pain behind the left eye, drowsiness/fatigue, and temporary palsy in bilateral arms.
She was admitted at the hospital for a few days for testing and observation. They gave her a mri, mrv, head ct scan, ekg, cbc, chemistry panel, and a sed rate. The results were all within the norm. She also had a few eeg's with at least 20 marked events that showed no abnormal brain activity. Electronic fetal monitering had good results and showed no reaction to the episodes. The last test they did was a lumbar puncture. Inital results were negative, but cultures are pending. While these tests were going on, they tried giving her trileptal, phosphenytoin, and ativan. The meds had no effect. From these findings, doctors have diagnosed that these are non-epileptic events.
I am not ruling out this conclusion, but my concern is that there could be something that they may be missing. My house is around 100 years old and I have been doing some remodeling. I tore down a ceiling a couple of months ago, exposing some mouse feces. More recently, I tore out a rotting bathroom floor to discover large amounts of mold beneath. Since then, a few people that were exposed to the mold spores have noticed some flu like symptoms. I'm hoping that if these elements are causing an infection that they'll show up in the cultures from the lumbar puncture. I also plan on sending in a sample of the mold in for testing.
My girlfriend's mental history is healthy. She has had no history of depression or anxiety. She is very mentally stable and seems to cope with things well. Her father suffered from severe depression and ultimately committed suicide 10 years ago. She was in a marriage for 4 1/2 years where she suffered physical and mental abuse. During this time, she never reported the abuse to anyone. She got divorced 6 1/2 months ago and has since moved on with her life. She has had some stresses with school, work, and chores around the house, but seemed to handle it well.
We plan to pursue psychotherapy, but in the mean time I would like to explore other options. I'm just wondering if anyone's heard of anything like this before. Any responses would be greatly appreciated.
