My husband has dementia/Alzheimer's and is experiencing tremendous head chatter. He hears/thinks events, conversations happen that never did. He is frantic about making a mistake when we are all very patient and kind to him. He says I make him very anxious, so I try to stay in the background as much as possible. We live with friends, husband and wife, who help me take care of my husband. Is all the head chatter part of this disease? Does it last until the person dies? Does it calm down if the person goes to a home? His memory seems to decline every day, but he is physically capable. The only people I have been around with this disease lost their memory but were not angry or frantic and hallucinating conversations that never happened.
You may want to download a 33 page booklet called Understanding the Dementia Experience by Jennifer Ghent Fuller. It's an excellent resource for you to learn about Alzheimer's from your husband's perspective.
Also the Alz.org website is a great resource with lots of information about AD along with an 800 phone number to call for advice,
Best of luck to you
