Too Old for Treatment?

I was diagnosed with MS late in life... I was pretty close to my 61st birthday. I know that the neurologist felt that I have PPMS.....there is every indication this was a valid diagnosis.

It is a known fact that as MS progresses it will no longer remit and relapse (RRMS) and becomes SPMS. This means that the patient no longer remits, just progresses. A lot of times, the progression is more active and harder to treat as the patient ages.
Then there are those of us who have never had an exacerbation... and we are diagnosed as Primary Progressive MS.

I also know that there is very little research being done on PPMS. Have you ever wondered why? Could it possibly be that being "old" might make the difference? After all, people of my age and beyond suffer from all sorts of maladies. So, how does a doctor or a research scientist figure out if it is MS or some other of a myriad of illnesses. Does the medical profession even try as hard to sort out the complications that come with age plus MS?

Hmmm, food for thought. I do hope age discrimination is not raising its ugly head.
