: I am confused about how MS is definitely ruled out. I had the conception that MS could be ruled out with negative brain/spinal MRI's, negative evoked potentials, and a negative spinal tap. Am I right? What other etiologies are considered after MS is ruled out? I have "MS-like" symptoms and all my tests are negative. My neurological exam was also
normalNormal saline flush. Lyme, ANA antibodies etc. were also negative. Do I still have to worry that I have MS even though my tests were all negative? I appreciate your response.

It is very difficult to give an absolute answer to a question like this, answers
can only be expressed in terms of probabilities.
I would be interested to know what your MS-like symptoms were, since the
possible range of symptoms is very broad and many other
disordersAdjustment disorder
Anorexia nervosa
Asperger syndrome
Autism
Autoimmune disorders
Bipolar disorder
Bipolar disorder
Bleeding disorders
Borderline personality disorder
Bulimia
Chronic motor tic disorder can overlap
in terms of individual symptoms.
I would also be interested to know if the
normalNormal saline flush neurological examination occurred
during or after your symptoms.
If you had a
normalNormal saline flush exam ,and all of those
normalNormal saline flush tests at the time of your
symptoms MS would be very unlikely, but it is not possible to say that the
diagnosis has been absolutely outruled especially whwn typical symptoms are being
encountered.
It would appear however, on the basis of the extensive testing that you have had that it
is not sufficiently likely to worry unduly about the posibility.
The other possibilities explored would be the ones that appear to have been
looked into already,
vasculitisNecrotizing vasculitis, Lyme disease and post-viral syndrome.
