Conversion disorder does not require a significant stressor to be present, although significant is a relative term in itself. That being said, an extensive work-up would include MRIs with/without contrast of brain, cervical spine, thoracic spine, lumbar spine +/- lumbar puncture. If this has all been done and negative, it is more likely conversion then a obscure neurological disease although the latter in itself is difficult to rule out.
Thank you for responding. I thought that required a pretty significant stressor. The only thing that's come up in the past couple of weeks is the nerve injury. Nothing else has really been stressful lately and her mental health has been under control. The altered mental status and muscle spasms left me with the injection that it is medical in nature. Also her history of neurological issues presenting over the past three years. I was thinking Todd Paralysis or MS might be more likely. They didn't do a spinal MRI, a spinal tap, or nerve conduction studies. Not sure if it was necessary or not.
