This category contains all missing persons with some form of dementia, including those with Dementia of Alzheimer’s Type. Gibb and Woolnough's Grampian Study provides a useful discussion on different forms of dementia.

There was a significant difference between the locations in which persons missing in farmland and urban areas were found, and in addition there was a significant gender difference for persons missing in farmland.

The following additional information was provided with regard to five incidents for which the location was reported as ‘open ground’:

"Hit a natural barrier and sat down, stuck in dense undergrowth, asleep on a park bench, found in thick bushes and found in a patch of overgrown nettles and grass."

There was no significant difference between the distances travelled by dementia sufferers and all the other categories in the study; there was, however, a significant difference between dementia sufferers missing in farmland and urban environments.
