Treatment of Neuropsychiatric Symptoms in Young Girls with Anorexia Nervosa
Young girls with anorexia nervosa presenting with neuropsychiatric symptoms require a multidisciplinary team approach that includes medical, psychiatric, psychological, and nutritional expertise for effective treatment. 1
Initial Assessment
- A comprehensive psychiatric evaluation should include weighing the patient, quantifying eating and weight control behaviors, and identifying co-occurring psychiatric disorders 1
- Physical examination must assess vital signs (temperature, heart rate, blood pressure, orthostatic measurements), height, weight, BMI, and signs of malnutrition or purging 1
- Laboratory assessment should include complete blood count, comprehensive metabolic panel, electrolytes, liver enzymes, and renal function tests 1
- An electrocardiogram is essential for patients with restrictive eating disorders or severe purging behaviors 1
Treatment Approach for Anorexia Nervosa with Neuropsychiatric Symptoms
Primary Treatment Recommendations
- Eating disorder-focused psychotherapy is the cornerstone treatment for adolescents with anorexia nervosa, addressing both eating behaviors and psychological aspects of the disorder 1
- For adolescents and emerging adults with anorexia nervosa who have involved caregivers, family-based treatment is strongly recommended 1
- Nutritional rehabilitation with individualized goals for weekly weight gain and target weight is essential 1
Managing Neuropsychiatric Symptoms
- Selective serotonin reuptake inhibitors may be beneficial for treating comorbid conditions such as anxiety, depression, and obsessive-compulsive behaviors that often present as neuropsychiatric symptoms 1
- For severe cases with significant neuropsychiatric symptoms, inpatient treatment should be considered, especially with severe medical conditions or comorbid psychiatric illness 2, 3
- Cognitive-behavioral therapy has shown effectiveness for addressing both the eating disorder and associated neuropsychiatric symptoms 4, 3
Special Considerations
- Young girls with BMI <16 kg/m² should be categorically restricted from athletic training and competition until treatment goals are met 1
- Future participation in sports should only be considered after treatment of the eating disorder, including achievement of BMI >18.5 kg/m², cessation of disordered behaviors, and close follow-up 1
- Risk factors associated with higher mortality rates that require more intensive intervention include longer illness duration (>10 years), lower BMI (<16 kg/m²), alcohol abuse, and poor social adjustment 1
Treatment Intensity and Setting
- Outpatient treatment is appropriate for most patients, but inpatient care is necessary when 2, 3:
- Severe medical complications are present
- Significant psychiatric comorbidities exist
- Outpatient treatment has failed
- Weight is dangerously low (BMI <16 kg/m²)
- Inpatient cognitive-behavioral treatment involving caregivers has shown effectiveness for adolescents with anorexia nervosa and associated neuropsychiatric symptoms 3
Follow-up and Monitoring
- Regular monitoring of weight, vital signs, and laboratory parameters is essential 1
- Ongoing assessment of neuropsychiatric symptoms and adjustment of treatment as needed 5
- Long-term follow-up is necessary as anorexia nervosa is often a protracted disorder requiring continued multidisciplinary care 2
Treatment Efficacy
- Parent-focused treatment, where therapists meet with parents separately while a nurse monitors the patient, has shown promising results in some studies 6
- Cognitive-behavioral inpatient treatment involving caregivers has demonstrated significant improvements in both weight restoration and psychological symptoms 3
- Early intervention is associated with better outcomes, particularly for adolescents 2, 3
