Context:

Anorexia nervosa (AN) is a severe psychiatric disorder with the highest mortality rate among eating disorders.
Prevalence has increased in adolescents since the COVID-19 pandemic.
AN is frequently associated with other psychiatric disorders and physical complications.

Purpose:

To review the current understanding of anorexia nervosa, including its prevalence, associated conditions, and treatment approaches.
To highlight the importance of early diagnosis and intervention.
To identify areas for future research.

Summary:

The highest mortality eating disorder, anorexia nervosa (AN), predominantly affects adolescents and young adults, with increased prevalence post-COVID-19.
Cognitive behavioral therapy and family-based therapy are primary treatments; innovative approaches show promise.
Psychopharmacotherapy lacks efficacy, except for olanzapine's moderate effect on weight gain.

Impact:

Emphasizes the critical need for early diagnosis and intervention in anorexia nervosa.
Highlights the limitations of current psychopharmacological treatments for AN.
Provides a roadmap for future research focusing on prevention, personalized treatment, and managing comorbidities.
