When Ron Husband started to forget things - dates, names, appointments... daft things, important things - it took a while to realise that this was 'a different form of forgetting'. But it was just the first sign of the illness that gradually took him away from the family he loved.

Pan ddechreuodd Ron Husband anghofio pethau - dyddiadau, enwau, apwyntiadau... pethau gwirion, pethau pwysig - mi gymerodd hi sbel cyn sylweddoli bod hwn yn fath gwahanol o anghofio. Ond dyma oedd arwydd cyntaf yr afiechyd a fyddai'n ei gipio i ffwrdd yn raddol oddi wrth y teulu a oedd mor annwyl ganddo.
