I recently stumbled across the website, patient.info, which is a resource for UK physicians about various disorders. The website contains a helpful page about caregiving for someone with dementia. Though it is written with physicians in mind (ie, how physicians can be supportive of families), I think the page provides a good summary for laypeople as well.
In addition, I think much of this article applies to caregivers who are NOT dealing with dementia. Much of the information and advice is generic.
Here’s a link to the full article:

Note that in the UK “caregivers” are referred to as “carers.” (It’s a superior term in my mind.)
