The latest on 'benign' MS
There was a study recently which followed a group of people with 'benign' MS. This means that multiple sclerosis is present, but there are few or no relapses and disability after a significant period of time. I guess it could be described as the 'best' kind of MS.
The latest study found that, often times, benign MS at 10 years can turn into a more progressive form at 20 years. And there were no clear characteristics which helped to determine the prognosis. The study also pointed to the fact that MRI lesions, while helpful, are probably only part of the picture. The theory is that, even in what appears to be normal brain tissue in an MRI, damaging activity can be occurring.
I'm assuming no one in the study was on one of the disease-modifying drugs (ABCR), since they were all thought to have had benign MS. A watch and see approach is often followed in these cases. The problem is we can observe symptoms and MRI results, but there could be hidden damage occurring which, over the course of time, can result in more disability.
I have relapsing-remitting multiple sclerosis. I take an agressive approach to it in taking an interferon treatment. I also ensure I follow my neurologist's advice and get regular MRIs and exams. It's important to identify what is in my control and what is not. That way, I can spend my time, energy, (and yes) worry on productive things I can do to help myself.
