Hi, I was with an MS specialist for four years. In 2001 I was admitted into hospital and at the end of the week he thought it was MS but rare not to show lesions.
I'd had previous ON and this showed up as atrophy on my brain MRI. I had other positive test results, including an abnormal neuro exam which showed problems in my spinal cord.
I was told it would be benign so wouldn't be getting DMD's. My major symptom was spasticity which usually means it's a chronic problem.
2005 my condition had progressed and I was told we know something is wrong we just can't identify it and I was discharged. I now needed a wheelchair outdoors.
Now 2012 I'm still trying to get the right diagnosis. I take lots of symptomatic meds but like Poll I know there aren't any drugs to slow my progression down.
There are many other things that it could be. The longer you go on with symptoms and progression and no lesions the less likely it is to be MS.
I know it's frustrating but it's for your benefit you get the correct diagnosis. I'm now seeing a Professor in neurogenetics.
I hope your neuro's come up with some answers.
