11.1 Prevalence and types of mental health disorders in adolescence

Adolescence brings a whirlwind of changes, including mental health challenges. From anxiety to depression, eating disorders to ADHD, many teens grapple with these issues. Understanding these disorders is crucial for supporting adolescents through this tumultuous time.

Mental health disorders affect about 20% of teens, with gender, socioeconomic status, and identity playing a role. Internalizing disorders like anxiety often fly under the radar, while externalizing ones like conduct disorder are more visible. Stigma remains a major hurdle in getting help.
