Hello,
@theonlooker, and welcome you to Talking Point. I'm sorry to hear about your dad's diagnosis, and that you've needed to come and find us.
You are in the right place, no worries!
My mother is 75 and has middle to later stage Alzheimer's. She was diagnosed with the dementia not quite four years ago, but in hindsight, definitely had it for some time before that, at least 2-3 years and probably quite a bit longer.
Even though I knew something was wrong with my mother, and her GP had said "maybe MCI?" I was startled and shocked by the Alzheimer's diagnosis and I remember that feeling all too well.
I also remember, again all too clearly, the feeling of being overwhelmed that you describe. It was such a shock, there was so much going on (she was in hospital and I needed to find a care home for her ASAP), and I knew nothing about dementia and had no idea where to turn.
I also found it a very, very steep learning curve in the beginning.
What did help me was getting some clear information.
A place you might start is here on the Alzheimer's Society website; they have a lot of good information and fact sheets that I have found clearly written and helpful.
You could look here for some general information about dementia:
https://www.alzheimers.org.uk/info/20007/types_of_dementia/1/what_is_dementia
And then maybe here, for info on the types of dementia:
https://www.alzheimers.org.uk/info/20007/types_of_dementia
(Before all of this with my mother, I didn't even know there are different types of dementia. I knew nothing, nothing at all. Don't feel discouraged, many of us start from the beginning.)
And there is a lot of other information there as well.
I also found, and still find, it helpful to just read through a lot of threads here on TP. Current ones, past ones, you name it, I've read it. Probably not for everyone, but it helped me.
Please don't hesitate to ask questions or for clarification about anything.
Feeling out of control seems to be a usual reaction to dealing with dementia.
If it's possible for you to have a conversation with your parents, or privately with your mother, and ask to be more in the loop with communication, perhaps you might consider that.
Unfortunately this is a disease where things get worse, so at some point, your mother, although she may prefer to do things herself or on her own, will need some help. If there's a way to gently set the stage for that and indicate to your parents that you want to be helpful and supportive, that's great. Being the only hands on caregiver for someone with dementia 24/7, forever, with no help, eventually takes its toll on the carer. We are only human.
Some things can be handled even from a great distance: online banking is a lifesaver, for example, or ordering supplies and groceries online, researching various topics, or even just regular phone calls or emails or Skype sessions.
Don't forget that you will need support as well, for you. Maybe a carers' group in your area (it can be immensely helpful to be in a room full of people who understand what you're going through), or someone to talk to, or whatever you need, but don't neglect yourself in the process.
Some good advice I often hear is that caring for someone with dementia is a marathon, not a sprint.
Dementia will eat up all the time and energy you throw at it and be greedy for more and that's true for your mum as well as you.
Again, I'm sorry to have to say it, but welcome to TP and hope there will be support and advice for you here. It's been a lifesaver for me. Best wishes to you and your family.
