Introduction: This research investigated the effects of violent and football video games on cognitive functions, cortisol levels, and brain waves. Methods: A total of 64 participants competed in a single-elimination tournament. Saliva samples of all players were obtained before and after the games for the assessment of cortisol levels. The cognitive performances of the players were also assess...

anxiety is one of the prevalent mental health disorders. stressors by changes in physiology can increase risk of physical diseases. high levels of cortisol have many negative effects on health. this study aimed to determine anxiety symptoms prevalence and its relationships with plasma cortisol level. this study was a descriptive- analytical cross-sectional that was conducted on 100 nursing stud...

INTRODUCTION Given that serum cortisol level interpretation in newborn infants (NBIs) is hard, the objective of this study was to correlate baseline salivary and serum cortisol levels and to describe salivary cortisol levels in the first month of life. POPULATION AND METHODS Descriptive, prospective, longitudinal, and correlational study. Term NBIs were selected from the Division of Neonatolo...

Cortisol is known to affect memory processes. On the one hand, stress-induced or pharmacologically induced elevations of cortisol levels enhance memory consolidation. On the other hand, such experimentally induced elevations of cortisol levels have been shown to impair memory retrieval. However, the effects of individual differences in basal cortisol levels on memory processes remain largely un...

Total and free cortisol levels are significantly elevated in pregnancy, but the reasons for this are not clear. The relationships between the diurnal variation in saliva (free) cortisol and baseline levels of total cortisol, corticosterone-binding globulin (CBG), progesterone, and estrogens were studied in several groups of women (normal nonpregnant, taking a combined oral contraceptive pill, a...
