Imagine how difficult it might be for someone with cognitive impairment–dementia to look at a list of information types in a small front in the middle of a page text. Now imagine that there is a better way. Look at the two diagrams (click to expand) and see if you think that some graphics scattered around a web page or report might make it a little easier to understand what is being said. Even for a PhD with 35 years of experience in work directly related to dementia.
And the cost of creating accurate and compelling is not that much.
See my point?
