Sorry to hear about the diagnosis. It’s worth looking out for any “newly diagnosed” days run by the MS Society/NHS trusts. I went to one of these and it was incredibly informative, great chance to put questions to neurologists and nurses.
What kind of MS has your Mum being diagnosed with? Is it relapsing remitting or progressive? That makes a difference to treatment options.
I understand MS diagnosis is less common for people in their 70s - but my (MS specialist) neurologist told me he had diagnosed someone in her 70s, so clearly it does happen.
There may be treatment for symptoms of MS, and/or DMTs to alter the course of disease.
If your Mum has relapsing remitting MS, presumably she is still at risk of relapse. So on that basis, they should offer her a DMT? Yes, the trials are on under 55s. They are also on people without co-morbities - they like to pick “ideal” candidates. But in the real world, the results have to extend to the rest of us…younger, older, with comorbidities etc.
Having said that, DMTs can weaken the immune system. That’s the point, in a way, since MS is an autoimmune disease. But it can make you more vulnerable to infections - some of which might be more serious at 76. So my guess is neurologists have to weigh these things up. How active is your Mum’s MS? Has she had recent relapses, for example? They might look at how stable the MRI is over time.
The advantage of the DMT is that, if it is effective, it can prevent the relapses which might, in turn, cause irreversible disability.
There have been some studies done on whether to “stop” DMTs once people reach a certain age, if they are stable. The idea was, perhaps they don’t need the DMTs and long term use might do more harm than good. The results I’ve seen were poor: i.e. even older people did benefit from continuing the DMT.
So… lots of issues here. I think it’s really important to make sure she has an experienced MS specialist neurologist and maybe get a second opinion on treatment…especially if they either exclude her purely on age grounds or seem not to be thinking it through carefully. Once you are on a DMT, regular monitoring can help pick up with things like a dangerously weak immune system.
Another thought: what vaccinations can your Mum get - covid? flu? shingles (very effective new shingrex vaccine)? - It’s often best to get vaccinations before you start on a DMT in any case.
Final thought: can anything be done to work on any other comorbities she may have?
