My wife woke up this morning thinking she had just been born so she said I was her father and she would not be able to walk, get washed etc. She was very vocal and it took the carer and I a long time to get her washed and dressed. It was a coincedence that her birthday is on the 15th Jan and it is the 15th today. She just told me it was all faked. Is this a common thing with this illness.
