Bettyspants - that has not been my experience at all.
I have spent the last year trying to get someone - anyone - to take the potential drug interactions that my son is on seriously.
So drug 1 - nasty side effects - initially told I was imagining it - then accepted.
So tried to get off drug 1. Couldn't.
So drug 2 introduced - as a swap. Except still couldn't get off drug 1. But it was noted that drug 2 stopped drug 1 side effects. So kept on it.
Drug 3 then introduced by a different doctor. I asked about the fact that everything says drug 3 should not be taken with drug 2 and he said that drug 2 was nothing to do with him.
So I went to the doctor who prescribed drug 1 & 2 who said he couldn't advise about drug 3. A ten second google tells me drug 2 & 3 should not be given together (drug 3 is essential, drug 2 is know to be highly addictive and hard to get off - drug 1 is meant to be easy to stop but we haven't managed it).
Drug 1 and drug 3 have known serious side effects and ds1 should be given routine blood tests. That has not happened.
There's a totally different standard of care for people with severe learning disabilities. And if you are non-verbal forget it. That is why the age of death is so much lower for people with severe learning disabilities.
As for anyone having any interest in how a child got into this state years ago - ha, forget it. I have given my suspicions - they have been accepted & made it onto letters (I seem to be deemed 'credible' by doctors). No-one has actually carried out any tests to see whether I might be right or wrong.
So no in my experience in people with learning disabilities nothing is taken very seriously. I seem to be deciding his seizure medication dose which is a joke (if I had my way he'd be on a different one as it's not controlling his focals imo).
