Neural correlates of altered insight in frontotemporal dementia: a systematic review

Highlights • Fractionating insight into objects aids its neuroanatomical exploration in dementia.• Distinctive neural correlates seem to underpin different insight objects in FTD.• Altered insight into disease/health condition mostly involves right frontal areas.• Altered insight into social cognition implicates frontal, temporal and limbic areas.• Frontal, medial temporal and parietal areas underpin insight into memory problems.
