In this method, mice were deprived from sleep for 5 days by using multiple platform method and Behavioral changes were evaluated using passive avoidance, Y-maze, Elevated plus maze and Morris water-maze tests.  Results: Sleep deprivation in mice showed significant decrease in learning and memory as behavioral changes studied from passive avoidance, Y-maze, Elevated plus maze and Morris water-maze tests.  Conclusion: This finding suggests that Chronic Sleep Deprivation can be cause of Alzheimer’s disease in their later life.
