What Causes Recurrent Pseudoseizures And Impaired Speech?

subject experiences a pseudo seizure like event frequently that causes her to cramp and contort at the hands, also is semi lucid, but speech is impaired. after massage and fairly violent neck adjustment producing loud deep cracking of the neck, she will immediately snap out of the degraded state with a sharp intake of breath and nearly vomits. At that moment she is completely aware and feels normal but doesn t remember the event. It seems that there may be pressure on the spinal cord due to maybe fluid build up or calcium spurs inside the vertebra? any thoughts?
