How does dementia affect the right temporal lobe?

Damage to the right temporal lobe leads to problems recognising faces and objects. The brain of a person with dementia with Lewy bodies (DLB) often shows less overall shrinkage than the brain of someone with Alzheimer’s or FTD. Instead, tiny deposits of protein (Lewy bodies) are seen in the cerebral cortex, limbic system and brain stem.
