I find that loss of insight varies a lot from one person with Alzheimer's disease Alzheimer's disease
A neurological disease that affects memory and behaviour. It is characterized by beta-amyloid plaques and neurofibrillary tangles in the brain. There is no known cause but genetics and lifestyle are thought to play a role. to the next. Some people, whose dementia otherwise is quite typical, will lose insight early in the course of their illness, whereas for others it is quite preserved. Very occasionally - I have seen it in about one patient in a thousand, but I have heard about it more often - some people with Alzheimer's disease who are treated will regain insight into their impairments, without regaining much function. This is a "worst case scenario" in which they have no beneficial treatment effect, and the only effect they have is distressing. Although very uncommon in my experience, I have often heard this story told by people who are against drug treatment Drug treatment
