however, the issues of old age walking issues are pretty much universal possibilities across all health conditions. just because some health issue occurs in a person with dementia does NOT necessarily mean it should be attributed to the dementia.
it is often more accurately attributable to old age and generally lowered immune systems. dementia is bad enough for families to deal with, without piling so much extra on it.
unfortunately we live in a time when most people have little to do with elders other than those in their own family. so most people have no idea what "normal" old age looks like for the majority of people.
basically what caregivers need to look for is a sudden change in health status -- whether a walking issue, emotional issue or whatever. it's the change that signals an issue, as opposed to the usual way of going on.
in dementia, those sudden changes needing attention include suddenly much more confusion, suddenly much more agitation, suddenly afflicted with walking difficulties. dementia itself doesn't include sudden downturns as its norm. so suddenly much-worse dementia means, "i'm really ill here, get me to the doctor!"
