My husband aged 50 has been diagnosed with congestive heart failure. I think because of untreated high blood pressure (hypertension)and has said a few 'odd' things, such as he was truly convinced our daughter used his mobile phone in front of him and she didnt! He has said that I have said things that I havent said, and been backed in that by the kids but husband insists I have said them! Now I recognise this behaviour as my mum has vas dems and Im her carer and Im so worried and scared that this may be the start of vas dems in my husband too. Am I over reacting? Is there a link with congestive heart failure and vas dems?
