First time Poster, Second experience with someone
having a seizure.

  General Info: I am a 49+ year old man in Ohio who
speaks via microphone and Yahoo Chat to a 48 year
old ladyfriend in Georgia.  We both are spinal
cord injuries (SCI).  High level cervical injuries,
each with 30 years of post injury time.  
WE both were injured at the age of 18.

  Recently it was determined by her doctors that she had
not been diagnosed at the time of her neck injury that
She had suffered TBI (traumatic brain injury.) Now she
experiences partial - complex seizures that causes her
to overload and shutdown (go to sleep).

(These were her words when she came to after 2 1/2 hours.    

"typing to u, talking and receiving echo, typing/reading
this afternoon was when I got confused....no seizure...
(Infact it was) I got very rattled and discombobulated.....
Your phone rang, and I got offline."  

  When we talk over the microphones, we get a feed back.
(echo-back).
I hear an occasional echo-back of my voice. I hear her over PC
speakers, she
hears through the earpiece of her microphone.  She hears echo-back of
her voice
almost with every sentence.  Her concern is if it might be this audio
disturbance that might help cause her drifting off and
And that is our question.
Can the sound of her voice echoing back help cause the overload and
her subsequent seizure?

  I am ignorant to this but care enough to seek advice which will be
most appreciated.  We are trying the process of elimination
