Poor sleep can accompany schizophrenia

The body’s internal biological clock coordinates a host of rhythms—from hormone production to sleep-wake times—on about a 24-hour cycle. Although everyone’s clock tends to run a little fast or slow, sunlight usually resets it. In people with schizophrenia, however, this clock can be seriously broken, a preliminary study finds.

Russell Foster of the University of Oxford in England and his colleagues strapped wristwatch-style activity monitors onto 14 volunteers with schizophrenia.
