　　Objective: To explore the characteristics of early sensory working memory deficits in Alzheimer's disease transgenic mice?

　　"Method: 5-week-old male 5XFAD transgenic mice and 9 wild-type mice, and 9-week-old male 5XFAD transgenic mice and wild-type mice were used. The sensory width of each test of the eight kinds of mice, the number of sensory recognition errors, and the accuracy of the sensory width test?

　　Result: Compared with wild-type mice of the same age, is the sensory width of 9-week-old transgenic mice significantly reduced (P0.05)?

　　Conclusion: 9-week-old 5XFAD transgenic mice have obvious sensory working memory deficits, suggesting that olfactory working memory deficits may be a sensitive indicator of early cognitive impairment in AD mouse models.
