My personal opinion is that the diagnosis of MS is getting better. My mother started having symptoms of MS in the late 70's and wasn't diagnosed until 1984! She went to doctor after doctor after doctor who told her she was either a. crazy or b. faking it
She finally went to see a doctor at UVA (she really didn't want to go because she was sure she would hear the same old same old) this doctor came in, looked over her chart and said "you either have a brain tumor or MS and you'd better hope its a brain tumor because we can do something about that" he predicted that she would be wheelchair bound in 2 years. Now in 2003, she uses a wheel chair only when going out to the mall or grocery and she uses a walker around her house. I have found in alot of MS patients I have met, that they tend to develop a stuborn streak, or maybe they have it to begin with!
My question is whether this higher number of MS diagnosis is due to better diagnostic tools or is there something going on that we aren't aware of yet?
I have heard the same asked about cancer. Are we just better at diagnosing cancer or is there something in our environment that is causing more cancers to devlop? My personal belief about MS and cancer is that the former is true. I think that out technology and diagnostic capabilities are so more advanced now that what would have previously gone undetected is now caught early.
Sorry for my longwinded response.
