@Togamay and firstly welcome to this friendly and supportive forum. There is lots of shared experience of dementia to be found here so I am glad you have found us.
I am sorry to read about your Mum's diagnosis and the fact that your father is her main carer. It's tough for sure.
Perhaps you might like to start a new thread, when you are ready, in the following section of the forum telling us a little more about your particular situation:
