I can't thank you all enough for your understanding and wise words. DH has been OK today but now, as it is approaching bedtime he has been scouring the house for the 'workmen' who were here today because their van is still outside. The reality is that there has been no one here but us chickens and the van belongs to an across the road neighbour and sits there every night. Like Annsixty's DH he regularly thinks the DGC are here and hiding from him.
The reason for the apparent rapid progress of DH's condition is that it took years to get a proper formal diagnosis as his symptoms did not appear to fit any of the types of dementia (and also, being a clever man) he managed to charm his way through verbal memory tests, blithely making up car registration numbers and avoiding the count backwards in 7's from 100 type by boring the tester to death with a long account of his problems with numbers caused by his 1st teacher in Primary school. I sat in on one test and although he did not get a single question right he was deemed to have only mild cognitive impairment. It has only been 6 months since, following a diagnostic brain scan, he was deemed to have mixed Dementia - Frontal lobal with Alzheimers. At that time the Consultant thought DH was in late Middle Stage.
Last Wednesday was his final day of 6 months of once a week Day Therapy but we have been fortunate that he has been awarded a place in an Alzheimers run centre for a half day a week and we will have a trial run of respite care for 3 days towards the end of January. His general health remains excellent and he is generally quite content, loves his meals, TV, the DGC, though he frets endlessly about the wheelie bin rota, any card which dares to park in front of our house, his medication, what day and time it is, fiddles with the central heating and TV controls, switches things - cooker, fridges, computer, etc off at the main switch if he notices they are on checks the car 4 or 5 times daily and recently lost the ability to make himself a cup of tea, or heat soup in the microwave. He point blank refuses to go in the bath or shower but takes 1.5 hours to wash and shave at the sink every morning.
Anyway, ask any of our friends or DH's relatives and they will confirm that DH's 'Maw' was in all respects the 'Mother In Law from Hell. I could go on all day and night listing the family celebrations she ruined, the things she called me, the way she treated her DH (a lovely man) her son and our DDs. In fact last night and today I have been unable to get her misdeeds out of my head, having scarce given her a thought since she died. Now I feel that the fickle finger of fate has brought her back into the centre of our lives - that she has literally 'come back to haunt me'.
