Individuals with neurodegenerative disease — Alzheimer’s disease and dementia are good examples of one of these — have a difficult time detecting lies and sarcasm, according to a study at the University of California, San Francisco.
The researchers asked a group of older adults (a mix of both healthy adults and those with neurodegenerative disease) to watch videos of conversations, some in which people were telling the truth and others where they were not.
Using magnetic resonance imaging (MRI), the scientists were able to determine which parts of the brain govern a person’s ability to identify sarcasm and lies. The images revealed the associations between the deteriorations of particular parts of the brain and the inability to detect insincere speech.
“These patients cannot detect lies,” said UCSF neuropsychologist Katherine Rankin, a member of the UCSF Memory and Aging Center and the senior author of the study. “This fact can help them be diagnosed earlier.”

The research is part of a larger study at UCSF’s Memory and Aging Center examining emotion and social behavior in neurodegenerative diseases as a way to better predict, diagnose and prevent these conditions. Read more: psychcentral.com
