Psychomotor slowness is associated with self-reported sleep duration among the general population

2010

Short and long self‐reported sleep durations have been found to be associated with several seemingly disparate health risks and impaired functional abilities, including cognitive functioning. The role of long sleep is especially poorly understood in this context. Psychomotor slowness, shown to have analogous associations with cognitive performance and health risks as self‐reported long sleep duration, has not been studied together with sleep duration in epidemiological settings. We hypothesized that self‐reported habitual sleep duration, especially long sleep, is associated with slow psychomotor reaction time, and that this association is independent of vigilance‐related factors. The hypoth…
