摘　　要：In this study, we investigated the effect of chronic exposure of low doses of Aluminum on affective and cognitive disorders in male and female rats. Twenty-five rats for each gender are used and the treatment carried out for 8 weeks. Animals received distilled water for control or an intraperitoneal injection of different doses of Aluminum: 0.125, 0.25, 0.5 and 1 mg/kg. Behavioral performance is measured in various tests mainly the Open Field, Elevated Plus Maze, Force Swimming Test, Morris Water Maze, Y-maze and Object Recognition Test. Al exerts anxiogenic properties and depressive effect. The effect begins at 0.25 mg/kg to reach a maximum at 1 mg/kg. In addition, chronic exposure to Aluminum causes cognitive disorders characterized by affection of memory and influence spatial learning performance. The effect of Aluminum on working memory is effective just at 1 mg/kg, while the effect on spatial learning performance begins at 0.25 mg/kg to reach a maximum at 1 mg/kg. In conclusion, Aluminum enhances anxiety and depression parameters and cognitive disorders characterized by the affection of memory and spatial learning performance.In this study, we investigated the effect of chronic exposure of low doses of Aluminum on affective and cognitive disorders in male and female rats.
