Objective: Salt is a compound used for taste and flavor in the daily diet. Although the World Health Organization (WHO) recommends salt consumption below 5g/day, the average worldwide is 15.24g. A high salt diet (HSD) causes cognitive impairment by increasing oxidative stress and inflammation. This study aimed to determine the effect of HSD on anxiety-depression-like behaviors and cognitive functions in female and male mice.
Materials and Methods: Twenty-eight mice (14 females, 14 males) were divided into four groups depending on gender (n=7): Male Control, Male HSD, Female Control, and Female HSD. Mice were fed an HSD for 16 days. Open-field (OFT), tail-suspension (TST), forced swimming (FST), and novel object recognition (NORT) tests were used. In addition, biochemical and histopathological analyses were made from brain tissues.
Results: Compared to their control in females with HSD, the time spent in the center (p<0.01) and the number of rearing (p<0.01) decreased in the OFT. Also, an increase in sedentary time in the TST (p=0.027) and; a decreased memory index (p<0.01) in the NORT, were determined. There was no difference in all tests in males with HSD compared to their control group. Oxidative stress increased in both genders (male: p=0.021, female: p<0.001) but was higher in females. Inflammation was increased in both genders. The damage to the brain region was increased in both genders, and this increase was more in females.
Conclusions: HSD affects female mice more through the cumulative effect of oxidative stress and inflammation, increasing depression and anxiety, and decreasing memory index.
