Is there a link between the two? I spoke to my elderly aunt on the phone who has been recently diagnosed with dementia and altzehmiers (according to my uncle). The conversation with my aunt was distressing as she sounded panicked and could not say a sentence without heavy breathing. This has come on within the last few months since I last spoke to her. She was hospitalized with a heart attack last year. Could the two be linked and what is her prognosis likely to be?
