BACKGROUND: Sleep is a physiological process that provides the body with a window for recovery and restoration. Intriguingly, even short-term sleep deprivation can impair brain memory, emotional capacity, information processing, and attention. Safflower (Carthamus tinctorius L.) has been shown to attenuate memory loss and improve anxiety and depression.
OBJECTIVE: This study aims to study the possible therapeutic effect of safflower on sleep deprivation-dependent effects on memory and behavior.
MATERIALS AND METHODS: Thirty young male Wistar albino rats were acclimatized, trained, and then assigned to three random groups: control (C), sleep-deprived (SD), and sleep-deprived Safflower-treated (SD+Sf) groups. Morris Water Maze (MWM) and Elevated Plus Maze (EPM) tests were used to study spatial memory and learning and anxiety-related behavior, respectively, in the study groups.
RESULTS: There was a significant deterioration in learning and memory, as tested by the MWM in the SD group, compared to the C group. This included prolonged test duration, reduced average speed, and longer travel distance. Treatment with safflower significantly improved MWM test performance in the SD+Sf group when compared to the SD group. When compared to the C group, rats in the SD group demonstrated altered EPM test parameters suggestive of anxiety-like behavior. These included spending more time in the closed arms, spending less time in the open arms, and having fewer entries in the open arms. Rats in the SD+Sf group showed improved EPM test parameters when compared to the SD group.
CONCLUSION: Safflower significantly ameliorated sleep deprivation induced by memory loss and altered behavior. Safflower supplementation may provide potential memory-enhancing and preserving, anxiolytic, and antidepressant therapeutic roles.
