Adolescence is also a time when many individuals begin engaging in sexually risky behavior . For example, approximately one-third of high school-aged girls and one-quarter of high school-aged boys have ever had sexual intercourse (CDC, 2017). Additionally, girls are nearly twice as likely as boys to engage in risky behaviors at a younger age (
The chronic level of glucocorticoids, and particularly cortisol, also affects the adolescent brain in a sex-specific manner. For example, levels of cortisol measured in saliva or blood are higher in males than in females, and the stress response is also more pronounced (Adler and Guella, 2009). Therefore, chronic stress during puberty can be more harmful to girls' neurodevelopment than it is to boys. In addition, girls' brains develop faster than boys', which has been shown to predispose them to greater variation in the timing of puberty across the menstrual cycle, which can further influence stress levels and the timing of the stress response (Moss et al., 2011).
The brain is remarkably sensitive to the changing levels of cortisol, adrenal androgens, and gonadal steroids throughout adolescence. For example, exposure to a single stressful challenge in childhood can have a profound impact on stress responses in adulthood (Uziel et al., 2011). Recent human brain imaging studies using fMRI and BOLD (which measures brain activity) have provided strong evidence that these steroid hormones and cortisol act upon the brain in a manner unique to each sex. In contrast to males, females have higher levels of adrenal androgens and lower levels of cortisol, and thus may be more vulnerable to the effects of stress (Bremner et al., 1995; Lutchmaya et al., 1995).
This chapter will first focus on adolescence-related changes in brain structure and function. We will then address the mechanisms that may explain the association between brain development and social and behavioral change during this period of life. Finally, we will consider possible interventions that might mitigate the harmful effects of stress.

One of the drawbacks to this approach was that we needed to recompile every time we made even a small change to the code. This slowed everything else we were doing down and because we couldn't always have someone waiting for the application to finish building. 827ec27edc
