My husband has been diagnosed with Alzheimer's early this year although he has been suffering for 3 or 4 years. Should I explain to him his parents are dead or wait for him to forget their planned visit?
Not sure where you're located, but I would highly recommend getting in contact with your local Alzheimer Society and speaking with a counselor. They will be able to help you to deal with these issues and more, and provide you with some education as well that will help to make this easier on you.
If telling your husband that his parents are deceased causes him stress or anxiety or sadness, I would suggest not telling him. If you have to give a little white lie to avoid the negative emotions that come with telling him again, it's OK. The term for this is called "therapeutic lying". And sometimes telling a Therapeutic Lie is more beneficial to the person than the truth because, often times, the person is beyond being able to understand the truth which causes a Domino Effect of other negative emotions.
