Since his diagnosis, Dr Zheng has gradually withdrawn from virtually all social activities. He is no longer able to play golf, mahjong or do crossword puzzles. Mrs Zheng does still encourage him to dance at home and he seems to get great enjoyment out of this.
His family have provided and continue to provide excellent loving care for Dr Zheng, but are finding it increasingly difficult to manage his physical and behavioural care needs.
Dr Zheng stopped driving 3 years ago.
