I've been helping look after my parents who both have dementia for the last 2 years or so.
Mum has non-fluent aphasia which first robs you of the ability to speak, then to communicate or understand at all. The wider symptoms come more slowly but are now well developed. She is now mute and so confusd/erratic that she had to go into a specialist hospital in October and is a shadow of her former self.
Dad has the more well known form and is extremely forgetful and often very confused about things, but is nonetheless able to have some quality of life. We hadn't noticed there was a problem until quite a long way into mums condition as her symptoms drowned his out.
It has been an extremely hard time, not least because my job means I can be anywhere in the country on any given day so I've been having to deal with the medical side while travelling or in between meetings. Watching them deteriorate and seeing dad's despair (as the one who can comprehend what is happenng) has been very sad. It's an incredibly cruel disease.
Nonetheless we came together yesterday and made the most of each other's company, first at my house and then at the hospital with Mum.
Make the most of time with your family as tomorrow is never promised.
