14 Nov Vitamin E may ease memory problems from lack of sleep – rat study

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.”
