In addition to the symptoms experienced in the early stages, all of which may deteriorate as time goes on, the person may experience:
Delusions
In mid-stage Alzheimer’s the person may strongly believe that other people are attempting to harm them or that people they always believed in are no longer trustworthy. This paranoia can take many forms, such as believing their partner is being unfaithful or that someone they know is stealing from them.
Hallucinations
Hallucinations may also begin at this stage of Alzheimer’s, more commonly so than in other forms of dementia. They may see and hear things that aren’t there, causing them to feel fearful, angry or upset, often unpredictably. They may also react strongly to their loss of independence and difficulty communicating.
