My 14 year old daughter has been told she has conversion disorder. After fainting, she cannot walk. She has reflexes in her legs, and can feel someone with something sharp pricking on them, but cannot stand. She will start counseling, and they have said that something has scared her into this state.
This was determined after an MRI, CATSCAN, and neuroligical testing. They assure me it is a temporay condition, and as soon as she finds out what has scared her, or is bothering her, she will walk again.
It is very scarey, but I have checked with many specialist, and it does happen.
