As for experiences with Dementia, my dad has it, I moved back home to help my mum cope with him. As there are varying degrees of it and it can affect suffers in different ways. Some unfortunately can become a real danger to not just themselves but others, unfortunately my dad can have massive mood swings and can become violent, something he never was before. I know how and why this happens, due to certain pathways and proteins in the Brain dying and when you can look at it from a far in a clinical manor its straight forward to understand; then dealing with it on a day to day practical basis it very difficult.
The days/nights I'm having to restrain my Dad because he's been attacking my Mum can be quite distressing, I have trained in martial arts over the years and even though I'm not the biggest of guys I can protect my quite well, though I never really gave any thought in having to do that with my parents.
The way Dementia, and mental health issues in general, are treated are appalling; I feel it is an area of healthcare which even in these times of financial cut backs should actually have increased funding, research and training on dealing with. This is not due to having my own personal experiences in this area, it is due to seeing the figures which are only due to rise with the increasing ageing population.
This could well be one of the largest expenditures of the Healthcare within the next 10 years; with looking to realistic ways of approaching the increased problems now then I do fear for people in the coming years who are going to have to live with this horrible disease.
