Past research has claimed lack of sleep can cause memory loss. Now, in what is deemed a first-of-its-kind study, researchers from the University of California-Irvine and Michigan State University suggest sleep deprivation could increase susceptibility to false memories.

The researchers note that although lack of sleep has been associated with impaired cognitive functioning, very few studies have investigated whether sleep deprivation contributes to false memories – the recall of an event that never happened.
