Summary: | Abstract Chronic stress has become a common problem that cannot be ignored and has become an important risk factor for the onset of many diseases. Responses to chronic stress are systemic reactions involving multiple organs and can induce symptoms such as depression, cognitive impairment, cardiovascular disease, immune dysfunctions, impaired reproductive ability, bone loss, and reduced life expectancy. Aim The present study was designed to investigate the effect of chronic restraint stress on the cognitive function in male albino rats, further to demonstrate its relation to amyloid and tau protein accumulation. Methods 24-albino male wistar rats were divided into 2 groups as Control group and Chronic restraint stress (CRS) subjected group (done by restraining rats for 3 hours daily for 4 weeks). Body weight, morris water maze test (MWM) and brain levels of p tau and amyloid beta were investigated Results CRS increased body weight significantly in week 4 and increased latency time as observed in MWM test compared to control group. Additionally, p tau and amyloid beta levels in CRS group were significantly increased. Conclusion chronic stress is able to accelerate the appearance of Alzheimer’s disease (AD) Changes upon chronic stress in the brain were related to accumulation of β-amyloid, TAU hyperphosphorylation in males. |
