Yes my Mum has.
Diagnosed witn Alz in 2013, but symptoms in hindsight about 2010/2011 and went into care 17 mnths ago.
Mum had a steady decline from 2013 to 2016, although beg of 2016 when she had several UTI's we did notice new behaviours that she didnt do prior.
Mum was stable in the first 7-8 mnths in care, and then developed two UTI's 2 mnths apart and has never been the same since.
Mum has declined as far as feeding herself with utensils. She will sit in front of her food as if she doesn't know what to do. The carers have to feed her. But then on the odd occasion she will pick her fork up, and feed herself, but can no longer use her knife.
Her toileting is a major issue, forgetting to wipe, forgeting to flush or wash hands. Mum refuses to use inco pads or pants. They do use disposable underwear, and have her on a toileting schedule.
Mums speech is often jumbled, and her sentences are generally Yes/No or less than 6 word sentences.
Unfortunately all of this has resulted in Mum taking to her room. Mood swings, aggression, agitation, hitting carers, hallucinating and delusions too. Refusing to join in activities, even music or dancing which was her favourite.
After blood tests/urine tests, and screening for delirium, everything was fine in that respect.
They have tried Mum with Lorazepam. This made Mum sedated and couldn't string a sentence together and wobbly on he feet. They tried upping her anti depressant dose. Nothing.
Since September they tried her with an antipshychotic Quetiapine.
This helped enormously for first months, and then again taking to her room,refusing to shower or dress.
They increased the dose, an yet again Mum calmed down, and better.... even managed to take her out which I hadnt done for 5 mnths.
Then again another dip down. They have increased dose 3 times.
So far so good but I feel helpless too
