Abstract

Objective(s) The present study aimed to investigate the effects of a fat soluble antioxidant, coenzyme Q10 (CoQ10) and folic acid on learning and memory in the rats with intracerebroventricular injection of streptozotocin (ICV-STZ), an animal model of sporadic type of Alzheimer's disease. Materials and Methods The lesion groups were injected bilaterally with ICV-STZ (1.5 mg/kg b.wt., in normal saline). In the treated groups, rats received folic acid (4 mg/kg; i.p.) or CoQ10 (10 mg/kg; i.p.), either alone or together, for 21 days. Passive avoidance learning test was used for evaluation of learning and memory. Results The results showed that learning and memory performance was significantly impaired in the rats with ICV-STZ (P< 0.001), however CoQ10 and folic acid, either alone or together, prevented impairments significantly (P< 0.001), as there was not any significant difference between these treated lesion groups and control group. Conclusion The present results suggest that CoQ10 and folic acid have therapeutic and preventive effects on cognitive impairments in Alzheimer’s disease.
