@bigdogpaws , I'm sure you're right, but stuff like this has been mentioned and received a flat refusal.
If she does get to see a GP or HCP (which she can't always avoid) she blithely tells them that everything's fine, and she doesn't need any help as her adult son lives with her. The latter is factually true - but his ND means that he can't see what needs doing, can't initiate action, has no social contacts to enable him to understand "normality" -- she cares for him as much as vice versa
He's learned how to do the dishwasher as she couldn't operate the new one. He can't use the washing machine, use a tin opener, change a lightbulb. He doesn't seem to see the dirt, the faeces, the rodents, the mould any better than she does.
I've alerted the GP surgery to the situation but my brother is registered with a different surgery so facts aren't joined up! And yes, I've said he should change GPs but what do I know? Ha!
I agree, I don't think she's able now to learn how to set up Alexa etc, even with help (I tried). But if she'd accepted the idea of a large button phone +/- speed dial a little while ago, she'd know how to use it by now! And it worries me that she could come to grief whilst my brother is out (he goes out regularly to walk the dogs - yes, there are two small trip hazards/infection risks aka terriers to add to the fun).
The last couple of years have brought some significant falls and a major heart attack so it would be sensible if she had the means to call for help independently. But (to continue the theme) what do I know? Ha!
