Anorexia nervosa in an elderly woman

Eating disorders, disordered eating, and body image research in New Zealand: a scoping review

BACKGROUND

The prevention and treatment of eating disorders relies on an extensive body of research that includes various foci and methodologies. This scoping review identified relevant studies of eating disorders, body image, and disordered eating with New Zealand samples; charted the methodologies, sample characteristics, and findings reported; and identified several gaps that should be addressed by further research.

METHODS

Using scoping review methodology, two databases were searched for studies examining eating disorders, disordered eating, or body image with New Zealand samples. Snowball methods were further used to identify additional relevant articles that did not appear in initial searches. Two independent reviewers screened the titles and abstracts of 473 records. Full text assessment of the remaining 251 records resulted in 148 peer-reviewed articles being identified as eligible for the final review. A search of institutional databases yielded 106 Masters and Doctoral theses for assessment, with a total of 47 theses being identified as eligible for the final review. The included studies were classified by methodology, and the extracted information included the study foci, data collected, sample size, demographic information, and key findings.

RESULTS

The eligible studies examined a variety of eating disorder categories including binge-eating disorder, bulimia nervosa, and anorexia nervosa, in addition to disordered eating behaviours and body image in nonclinical or community samples. Methodologies included treatment trials, secondary analysis of existing datasets, non-treatment experimental interventions, cross-sectional observation, case-control studies, qualitative and mixed-methods studies, and case studies or series. Across all of the studies, questionnaire and interview data were most commonly utilised. A wide range of sample sizes were evident, and studies often reported all-female or mostly-female participants, with minimal inclusion of males and gender minorities. There was also an underrepresentation of minority ethnicities in many studies, highlighting the need for future research to increase diversity within samples.

CONCLUSION

This study provides a comprehensive and detailed overview of research into eating disorders and body image in New Zealand, while highlighting important considerations for both local and international research.

Treatment of eating disorders in older people: a systematic review

BACKGROUND

Historically, eating disorders were not identified in older populations and it is only in more recent times that there is greater recognition of the existence of eating disorders among the elderly. This is despite the high level of morbidity and mortality associated with these disorders. Current guidelines focus on treatment of eating disorders within the adolescent and general adult age groups, without apparent concessions made for the older age group. The aim of this study was to review existing literature on the demographics and treatment of eating disorders in older people.

METHODS/DESIGN

A systematic review of the literature was conducted using CINAHL, MEDLINE, EMBASE, PsycInfo, Scopus, and Web of Science to identify publications focusing on treatment of eating disorders in people over the age of 65 years, age of diagnosis, gender distribution, treatment setting, and treatment outcomes.

RESULTS

A total of 35 articles (reporting on 39 cases) were relevant to our study, with 33 of the 35 articles being either case studies or case series. The mean age of participants was 73.2 years (range 66-94 years) with the majority (84.6%) being female. Most cases (84.6%) were diagnosed with anorexia nervosa, and 56.4% of all cases were reported as late onset (i.e., after age 40 years). The vast majority (94.8%) received treatment, of which 51.5% was hospital-based treatment. In case descriptions where improvement was reported, the majority described a multidimensional approach that included a combination of hospital admission, therapy and pharmacotherapy. Overall, 79.5% of cases who underwent treatment for an eating disorder improved, while 20.5% relapsed or died as a result of the complications from their eating disorder. There were significant inconsistencies and omissions in the way cases were described, thereby impacting on the interpretation of the results and potential conclusions.

CONCLUSIONS

The information available on the treatment of eating disorders in people over the age of 65 years is limited. The quality of case reports to date makes it difficult to suggest specific assessment or treatment guidelines for this population.

Brain Stimulation in Eating Disorders: State of the Art and Future Perspectives

The management of eating disorders (EDs) is still difficult and few treatments are effective. Recently, several studies have described the important contribution of non-invasive brain stimulation (repetitive transcranial magnetic stimulation, transcranial direct current stimulation, and electroconvulsive therapy) and invasive brain stimulation (deep brain stimulation and vagal nerve stimulation) for ED management. This review summarizes the available evidence supporting the use of brain stimulation in ED. All published studies on brain stimulation in ED as well as ongoing trials registered at clinicaltrials.gov were examined. Articles on neuromodulation research and perspective articles were also included. This analysis indicates that brain stimulation in EDs is still in its infancy. Literature data consist mainly of case reports, cases series, open studies, and only a few randomized controlled trials. Consequently, the evidence supporting the use of brain stimulation in EDs remains weak. Finally, this review discusses future directions in this research domain (e.g., sites of modulation, how to enhance neuromodulation efficacy, personalized protocols).

A retrospective case series of electroconvulsive therapy in the management of comorbid depression and anorexia nervosa

OBJECTIVE

Major depressive disorder (MDD) is common in anorexia nervosa (AN), associated with worse outcome and greater suicide risk. Electroconvulsive therapy (ECT) is highly effective in the treatment of MDD refractory to antidepressive treatment. We describe a case series of female adolescents with AN receiving ECT for MDD resistant to treatment and/or with severe suicide risk.

METHOD

We retrospectively analyzed the files of all 30 adolescent females hospitalized in our department because of AN between 1998 and 2017 and treated with ECT. Severity of eating disorder (ED) and depressive symptoms was retrospectively assessed using the Clinical Global Impression-Severity Scale.

RESULTS

Patients were severely depressed and suicidal on admission. All were resistant to antidepressants. A significant deterioration in depression, with severe suicidality, occurred from admission to pre-ECT, with concomitant improvement in ED symptoms and increase in body mass index (BMI). Significant improvement in depressive and ED symptoms and increase in BMI occurred following ECT, continuing to discharge. Adverse effects were mostly minimal. Fifty-three percentage of the patients were rehospitalized within the first year after ECT, mostly because of deterioration of depression and attempted suicide. Several years after discharge, 46.6% of the patients had no evidence of depression, suicidality, and ED-symptomatology, and another 23% had only evidence of ED symptomatology.

DISCUSSION

ECT is safe and well tolerated in AN with severe comorbid treatment resistant MDD and/or with increased suicide risk. Many AN patients undergoing ECT may be remitted at long-term follow-up.

The Use of Electroconvulsive Therapy in Eating Disorders: A Systematic Literature Review and Case Report

OBJECTIVE

The aim of this study was to determine the potential for safe and effective use of electroconvulsive therapy (ECT) in treating eating disorders (EDs) in patients with and without comorbid psychiatric disorders.

METHODS

A review of the literature pertaining to the use of ECT in patients with EDs was performed through PubMed, PsycINFO, and MEDLINE. Search terms included "Electroconvulsive Therapy," "ECT," and "Electroshock" each combined with "Anorexia Nervosa," "Bulimia Nervosa," "Binge Eating Disorder," "Eating Disorder," "EDNOS," and "OSFED." Additionally, a case in which ECT was used in treating a patient with anorexia nervosa is presented.

RESULTS

Eighty-nine articles were reviewed, and 11 were selected for inclusion. These articles detailed 14 patients with active EDs who received ECT during their course of treatment. Of these patients, 13 were noted to have shown improvement in disordered eating after receiving ECT, and no adverse medical outcomes were reported. Our case detailed an additional patient who benefitted from ECT.

CONCLUSIONS

There are limited data supporting the use of ECT in treating EDs; however, there is evidence to support that ECT is safe in this population and has been effective in cases of patients with AN with and without psychiatric comorbidities as well as binge eating disorder. More research is needed for treatment guidelines.

Unexplained weight loss in an 80-year-old woman

An 80-year-old woman presented with long-standing history of weight loss and malnutrition, which had caused her to become reliant on the use of a wheelchair. Her symptoms were initially attributed to her medical comorbidities, however, during admission it became apparent that she had been suffering from depression and had gone on to develop an eating disorder. Eating disorders are most common in young adults but can affect all age groups, including the elderly population. The diagnosis is rarely considered in such patients and easily overlooked, especially when in the presence of chronic conditions and cognitive decline. A pre-existing psychiatric issue, most often depression, may also be present in this age group. There are no current treatment methods targeting patients in this population, who may not respond as effectively to the available strategies directed at young adults. It is important to always consider an eating disorder as a contributor or direct cause of unexplained weight loss in elderly patients.

A case of anorexia nervosa in an elderly man

OBJECTIVE

To explore aspects of anorexia nervosa occurring in older populations, especially men, by reviewing the literature and presenting a case study of an elderly man with unexplained vomiting and weight loss.

METHOD

The literature is reviewed and an illustrative case study of an elderly man with unexplained vomiting and weight loss is described.

CONCLUSIONS

Anorexia nervosa is an uncommon cause of unexplained weight loss in the elderly, but may be under-recognized and associated with a high level of mortality.

Late onset eating disorders in Spain: clinical characteristics and therapeutic implications

OBJECTIVE

The literature on later age of onset (LAO) in women with eating disorders is scarce. We compared the severity of eating disorders, eating disorder subtype, and personality profiles in a clinical sample of consecutively assessed women with eating disorders with later age of onset (LAO, > = 25 years) to women with typical age of onset (TAO, <25 years).

METHOD

All eating disorder patients met the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) criteria and were admitted to the Eating Disorder Unit of the University Hospital of Bellvitge in Barcelona, Spain. Ninety-six patients were classified as LAO and 759 as TAO.

ASSESSMENT

Measures included the Eating Attitude Test-40 (EAT-40), Eating Disorders Inventory-2 (EDI-2), Bulimic Investigatory Test Edinburgh (BITE), Symptom Checklist Revised (SCL-90-R), and the Temperament and Character Inventory-Revised (TCI-R), as well as other clinical and psychopathological indices.

RESULTS

LAO individuals reported significantly fewer weekly vomiting episodes, fewer self-harming behaviours, less drug abuse, and lower scores on the BITE symptoms, the EDI-2 drive for thinness, and the TCI-R harm avoidance scales than TAO individuals. Conversely, the LAO group reported more current and premorbid obesity than the TAO group.

CONCLUSION

LAO eating disorder patients in this sample presented with milder symptomatology and less extreme personality traits. Premorbid obesity may be more relevant to LAO than TAO eating disorders and should be routinely assessed and considered when planning treatment.

Eating disorders in older women: does late onset anorexia nervosa exist?

OBJECTIVE

The objective of this study is to determine whether eating disorders can present for the first time in older people.

METHOD

This is a descriptive study of patients above the age of 50 years who have presented to a national eating disorder center within the last 10 years.

RESULTS

Thirty-two patients were identified; data were available for 26 of these patients and 11 agreed for further interview and questionnaire completion. There were no cases where the eating disorder had its onset late in life. Of the 11 interviewed, six participants retained a diagnosis of anorexia nervosa, four had Eating Disorder Not Otherwise Specified and only one was recovered. Comorbid depression was universal in those still suffering with an eating disorder diagnosis, and their level of social functioning was impaired.

DISCUSSION

Anorexia nervosa is a chronic and enduring mental illness that, although rare, can be found in older people. In our sample, we found no evidence of late-onset disorders; all described cases were lifelong.

Eating disorders in the elderly

BACKGROUND

Eating disorders in the elderly are often overlooked. When they occur, significant morbidity and mortality result. In this study we review all existing literature on eating disorders in the elderly and provide practical guidelines for clinicians in recognizing and managing eating disorders in the elderly.

METHODS

A literature search using Medline, PubMed, Web of Knowledge, and PsychINFO revealed 48 published cases of eating disorders in people over the age of 50 years.

RESULTS

The mean age was 68.6 years (range 50-94), and the majority (88%) of cases were females. The majority (81%) of cases had anorexia nervosa, and 10% had bulimia nervosa. Late onset eating disorders were more common (69%) than early onset. Comorbid psychiatric conditions existed in 60%, most commonly major depression. Management with a combination of behavioral and pharmacologic interventions was most successful, although only 42% were treated successfully. Mortality was high (21%) secondary to the eating disorder and its complications.

CONCLUSION

Eating disorders do occur in the elderly and should be included in the differential diagnosis of unexplained weight loss in the elderly.

Severe anorexia nervosa, co-occurring major depressive disorder and electroconvulsive therapy as maintenance treatment: a case report

Introduction

It is difficult to treat patients who, in addition to having severe anorexia nervosa, also have severe symptoms of major depressive disorder and a tendency for impulsive acting out behaviour. Our case report considers the feasibility of maintenance electroconvulsive therapy in such complicated cases.

Case presentation

This is a case report of a woman with anorexia nervosa and co-morbid severe major depressive disorder who was treated with electroconvulsive therapy as a maintenance treatment.

The maintenance electroconvulsive therapy was conducted without immediate complications. It had a positive effect on the patient's depressive symptoms and lability and her general wellbeing, although some cognitive deficits were observed.

Conclusion

The maintenance electroconvulsive therapy seemed to support recovery in a case of refractory anorexia nervosa and a tendency for labile mood. The symptoms of co-occurring major depressive disorder were partly relieved and maintenance electroconvulsive therapy had some positive effect on weight gain.
