"Anorexia saved my life": coincidental anorexia nervosa and cerebral meningioma

Presenting Psychiatric and Neurological Symptoms and Signs of Brain Tumors before Diagnosis: A Systematic Review

Brain tumors can present with various psychiatric symptoms, with or without neurological symptoms, an aspect that complicates the clinical picture. However, no systematic description of symptoms that should prompt a neurological investigation has been provided. This review aims to summarize available case reports describing patients with brain tumors showing psychiatric symptoms before brain tumor diagnosis, in order to provide a comprehensive description of these symptoms as well as their potential relationship with delay in the diagnosis. A systematic literature review on case reports of brain tumors and psychiatric symptoms from 1970 to 2020 was conducted on PubMed, Ovid, Psych Info, and MEDLINE. Exclusion criteria comprised tumors not included in the World Health Organization (WHO) Classification 4th edition and cases in which psychiatric symptoms were absent or followed the diagnosis. A total of 165 case reports were analyzed. In a subset of patients with brain tumors, psychiatric symptoms can be the only manifestation or precede focal neurological signs by months or even years. The appearance of focal or generalized neurological symptoms after, rather than along with, psychiatric symptoms was associated with a significant delay in the diagnosis in adults. A timely assessment of psychiatric symptoms might help to improve early diagnosis of brain tumors.

Patients with eating disorders showed no signs of coeliac disease before and after nutritional intervention

AIM

This study assessed the presence of specific antibodies for coeliac disease in outpatients suffering from eating disorders before and after nutritional intervention. We also evaluated whether those patients should undergo regular screening for coeliac disease.

METHODS

The sample consisted of 154 patients with a mean age of 16.7 years - ranging from one to 19 years of age - suffering from eating disorders. Serology screening for coeliac disease and total immunoglobulin A (IgA) levels was evaluated in the 154 children before the nutritional intervention and in 104 patients after the intervention. The patients consumed an adequate amount of gluten in both phases.

RESULTS

Postintervention evaluation revealed that 92 patients (88.5%) achieved a normal body weight, while the remaining 12 (11.5%) became obese. Postprandial abdominal discomfort and pain were resolved. The serology tests were negative in all patients, before and after intervention. None displayed IgA deficiency.

CONCLUSION

To the best of our knowledge, this was the first prospective study where patients underwent a screening serology for coeliac disease before and after nutritional intervention. No indication of the coexistence of eating disorders and coeliac disease was documented, and the patients in our study were unlikely to require regular screening for coeliac disease.

Psychiatric symptoms causing delay in diagnosing childhood cancer: two case reports and literature review

INTRODUCTION

A somatic disorder may initially be overlooked when a child presents with psychiatric symptoms. We report two children with anorexia nervosa as initial diagnosis and in whom there was a delay in the final diagnosis of the underlying malignancy. A literature survey was performed including patients under 18 years of age with psychiatric symptoms in whom later on an oncological diagnosis became evident as an explanation.

RESULTS

We have found 30 additional cases, with a median delay of 12 months until the diagnosis of the tumour. Overall, 16 boys and 16 girls had a solid tumour: 26 central nervous system tumours, 3 tumours of the gastrointestinal tract and 3 others. In 25 out of 32 patients anorexia nervosa was assumed, although it always appeared to be atypical. Patients younger than 7 years had a significantly longer delay until final diagnosis, while no other patient characteristics correlated with such delay.

DISCUSSION

In addition to careful physical (including full neurological) examination, we advise additional neuroimaging especially in each case of atypical presentation of anorexia nervosa, in order to avoid a delay in diagnosis of a possible malignancy. Furthermore, it is desirable to perform a re-examination when a psychiatric disorder does not respond to therapy, in order not to overlook an underlying oncological disease.

Cancer and anorexia nervosa in the adolescence: a family-based systemic intervention

Objective. Anorexia nervosa is difficult to diagnose in cancer patients since weight loss, aversion for food, and eating disturbances are frequent in patients undergoing chemotherapy and radiotherapy. Nevertheless, efforts are mandatory to recognize and manage this condition which may occur also in cancer patients with a special regard to adolescents. Methods. Through the clinical history of Anna, a 15-year-old adolescent with advanced cancer, we describe the effectiveness of a family-based systemic intervention to manage anorexia nervosa occurring in concomitance to osteosarcoma. Results. Through a two-year psychotherapy period involving different techniques applied to the whole family such as family genogram, family collage, and sculpture of family time, Anna was relieved from her condition. Conclusions. Upon early diagnosis and appropriate treatment, anorexia nervosa can be effectively approached in adolescent cancer patients. The presence of a life-threatening medical condition such as cancer may provide motivation for a patient to control disordered eating behavior in the context of an appropriate family-based systemic intervention. The general frame of anorexia occurring in cancer-bearing adolescents is reviewed and discussed.

Anorexia nervosa and brain tumor in a 14-year-old girl

A 14-year-old girl with anorexia nervosa (AN) was found to have an intracranial neoplasm. Atypical psychological symptoms prompted further evaluation, including electroencephalogram and neuroimaging, which revealed a sellar and suprasellar mass. This patient had an eating disorder and a brain tumor, which appear to be two unrelated conditions. However, it remains unclear how each affected the other. The diagnosis of AN, like all other psychiatric disorders, requires that possible medical etiologies and coexisting medical problems be excluded. AN and other eating disorders are particularly difficult to diagnose in children and adolescents because they often do not present in the manner typical of adults. Perceptual and cognitive disturbances associated with AN are difficult to evaluate because children and adolescents normally change over time as they progress through different stages of development. Therefore, it is particularly important to evaluate for the presence of medical conditions when a diagnosis of an eating disorder is made in a child or adolescent.

Clinical implications of brain imaging in eating disorders

Imaging studies have greatly improved the understanding of the pathology and physiology of psychiatric disorders, such as schizophrenia, affective disorders, obsessive-compulsive disorder, and Tourette syndrome. In the past few years, several neuroimaging studies have concentrated on patients with eating disorders. Although the number of studies is small compared with studies of other psychiatric disorders, the results are beginning to highlight potential areas in the brain that may lead to a better understanding of these disorders. Much research still is needed, and replication of results across centers is needed. The brain is an extremely complex organ; that eating disorders are a result of abnormalities in one specific area of the brain is unlikely. More likely is that several components of the brain have a role, including cortex and subcortical regions and involvement of several neurochemical pathways and circuits within the brain. Further studies are needed in this exciting development of research about eating disorders.
