Mum has changed dramatically over the past six months (her diagnosis over five years ago now), what scares me is the pace of which this deterioration has happened during this period. Her level of engagement has dropped off and her ability to communicate verbally is practically nil (although she can have an occasional lucid day). Similarly she is unable to process what I am saying; again don't get me wrong we more than manage to decipher each other's exchanges but it is upsetting seeing how frustrated mum can become..
