A team of researchers at the University of California, San Francisco have found that older people who fail to recognize lies or sarcasm may be showing early signs of progressive dementia.
Frontotemporal dementia, or Pick's disease, is a rare form of dementia that affects frontal and temporal lobes of brain. People suffering from this condition lose the ability to detect sarcasm or lies as compared to people who age normally, the researchers said.
"If somebody has strange behavior and they stop understanding things like sarcasm and lies, they should see a specialist who can make sure this is not the start of one of these diseases,” the Live Science quoted lead researcher Katherine Rankin, a neuropsychologist at the University of California, San Francisco, as saying.
