Daily doses of vitamin E may improve memory associated with a lack of sleep, suggests new data from rats.
Sleep deprived rats given a daily dose of vitamin E displayed increased
levels of antioxidant defenses, as well as an amelioration in the
impairment in short- and long-term, according to research.
«The current study is unique in taht in it is the first to examine the
interactive effects of chronic sleep deprivation, and chronic
administration of vitamin E (for 6 weeks)».
«Result of the current study show that administration of vitamin E did
not affect memory functions in normal animals. However, it preserved
memory during sleep-deprivation.»
Result showed that sleep deprived animals showed a decline in short- and
long-term memory, but vitamin E «prevented such effects». Additionally,
the vitamin E doses were associated with improvements in the activity
of a number of antioxidant enzymes, which otherwise decrease during
chronic sleep deprivation.
«In conclusion, sleep deprivation induces memory impairment, and vitamin
E prevented this impairment probably through its antioxidant action in
the hippocampus.»
