Abstract
Objective To evaluate the impact of psoriasis on spatial learning and memory abilities in mouse models by using Morris water maze. Methods Twenty healthy male C57BL/6J mice aged 10 months were randomly and equally divided into 2 groups: psoriasis group topically treated with imiquimod 5% cream on the back once a day for a week, and control group topically treated with vaseline once a day for a week. After successful establishment of mouse models, the Morris water maze (MWM) test was used to assess the learning and memory abilities in the mice in the 2 groups. Results In the place navigation experiment, the escape latency was significantly longer in the psoriasis group (38.24 ± 13.59 s) than in the control group (14.28 ± 3.80 s, t = 5.37, P 0.05) . Conclusion The spatial learning and memory abilities were impaired in the mouse model of psoriasis. Key words: Psoriasis; Cognition disorders; Learning disorders; Memory disorders; Disease models, animal; Morris water maze
