Hi Tin,
It sounds like you are having an awful time at the moment
I wish you had a CPN or SW that you were able to access for support - I find it unbelievable that you, and so many others seem to be just left to get on with it. I may have to scream and shout at times, but at least I do have someone 'named' and familiar in the form of Mil's CPN, as a starting point.
We have issues with Mil 'leaning', but from your description, it sounds different to what your Mum is doing - Mil tends to lean forward, almost at a 'tilt' and walking with tiny, fast, 'shuffly' steps - it almost looks like her feet are rushing to catch up with her head, and obviously a big danager with her overbalancing and falling. She can sort of 'list' to the side, leaning slightly to the right, its but more that she seems not to be able to walk in a straight line and veers off instead. Its intermittant (though seen more and more frequently as time goes on) and the more agitated she is, the more she paces, the worse it gets. Consultants views vary - one says she has Parkinsons, another says no, the dementia is just causing her to display 'Parkinson like symptoms, including Parkingsons gait'. Either way, I don't think that's like what you are describing with your Mum, is it?
I do, however, know exactly what you mean about the creative 'reasons' - with Mil it isn't on the phone wanting someone to visit, its the reasons she gives for why she has to go 'home, right now' - its because her Dad is ill and she has to see how he is, its because her parents are expecting her, her Mum will have a meal ready, her parents will be worried, her parents/Auntie/nephew are looking after her little one and she has to get back, she has left a child there alone and must get back, she has a cat there that needs feeding or a dog that needs walking, she has left all her clothes there, her friends are meeting her there, her nephew is picking her up from there, she has left all her money there . . . the list is endless. And I am never 100% sure to what extent she is aware that she is 'making up' reasons for having to leave. Sometimes I feel she guenuinely beleives that her parents are worried or that she has a child 'at home' who needs her - but occasionally, whilst I think the desire to go home is very real, I suspect that she 'makes up' the excuses simply hoping to persuade us to take her. Either way, the variety and sheer inventiveness is amazing!
I can also relate to the periods of time where changes and decline are rapid, big and very noticable
I really hope that the lavender helped last night and that you both got some rest, Hun xxxxxx
