(Columbus Dispatch) There is no way to diagnose a stroke before it happens, but researchers say they have identified a clue to help doctors predict who is at risk: the amount of sleep a person gets at night.
Older adults who said they slept more than eight hours were 46 percent likelier to suffer strokes in the next decade than adults who slept for six to eight hours, according to an analysis published in the journal Neurology.
Even worse, the stroke risk for people who went from sleeping less than six hours to sleeping more than eight hours was almost four times greater than for people who consistently got six to eight hours of sleep.

The findings might help clarify the fuzzy relationship between sleep and stroke. A variety of studies have considered the issue, with inconsistent results.
