Abstract

Age-related changes in sleep are observed in many species, including rats and humans. Old rats often exhibit less total and paradoxical sleep, shorter sleep bouts and more random sleep-wake periods across 24 hours, than young rats. This paper evaluates recent evidence that deterioration of selected sleep parameters, usually involving levels of paradoxical sleep or durations of sleep bouts, may be related to deterioration of memory in old rats. Similar findings are reviewed with respect to young animals with different forms of experimentally-induced amnesia. Furthermore, a drug that enhances memory in rats and old humans, glucose, also enhances paradoxical sleep in old rats. These data suggest the utility of sleep measures as neurobiological markers of memory dysfunction in old rats.
