Gullibility, inability to detect sarcasm 'indicators for dementia'

Posted on 18 April 2011

People who are especially gullible or unable to detect sarcasm could be exhibiting early signs of dementia, new findings have shown.

In a study at the University of San Francisco, older people with and without neurodegenerative conditions were asked to assess videos of people who were either being deceitful or truthful.

Researchers used MRI scans to identify a link between which participants had experienced deterioration in particular sections of the brain, and those who were more gullible.

According to lead author Katherine Rankin: "These patients cannot detect lies.

"This fact can help them be diagnosed earlier."

In other news, a study has suggested that people with stroke and heart disease risk factors could be at a higher chance of experiencing cognitive decline.

People with elevated cardiovascular risk factors were found to experience a greater decline in verbal fluency and the ability to ignore irrelevant information.
