Alzheimer’s disease is strongly correlated with learning and memory impairments. As exercise can enhance memory and learning, in this study, we have investigated the effects of treadmill exercise on memory impairment in amyloid β (Aβ)- treated rats focusing on brain-derived neurotrophic factor (BDNF) expression. Methods: Wistar male rats received intracerebroventricular (ICV) injection of Aβ and exercised on a treadmill for one month. Memory function was assessed using Morris water maze (MWM) and avoidance learning tasks. The level of BDNF was examined by the ELISA test. Results: The results of MWM and avoidance learning tasks showed that treadmill exercise could improve Aβ- induced memory impairment significantly. Moreover, BDNF expression increased following exercise in the Aβ- treated rats. Conclusion: The present results suggested that treadmill exercise may improve memory in Alzheimer’s disease by increasing BDNF level in the hippocampus.
