Both parents have/had vascular dementia and lived together in a care home. Mum passed away on Friday and dad was told by my brother and said “oh really”. Since then when we have chatted to him not once has he mentioned mum. We don’t know what to do Should we mentioned mum or ignore her in our conversations. He recognizes us no problem and we would like to ask if he knew of any of mum’s wishes after passing away. Just really don’t know how to handle this situation.
