Sarcasm may be considered the lowest form of humor, but some scientists are finding it useful as a tool to diagnose dementia. Researchers at the University of New South Wales found patients with a common form of dementia cannot detect when someone is being sarcastic. That's because they don't pick up on discrepancies between a person's words and the tone of their voice.

Researchers say the sarcasm test could replace some more expensive tests for dementia.

The research is published in the new issue of the journal Brain.
