Hello
@MinaBina and firstly welcome to the Dementia Support Forum. We are a very friendly and supportive bunch of people with shared experience of the various aspects of dementia.
I am sorry to read about your husband, and what you suggest is the progression of the Alzheimer's. Dementia affects everyone slightly differently with sometimes differing symptoms shown, or different behaviours. There is no one step fits all, and it is quite possible that his health condition is progressing.
If you have any particular questions, please do ask away, as members here really do want to help. You will always find understanding and a listening ear. This link may help with information:
Dementia is progressive. This means signs and symptoms may be relatively mild at first but they get worse with time. Dementia affects everyone differently, however it can be helpful to think of dementia progressing in 'three stages'.
