RESUMEN

Severe and Enduring Anorexia Nervosa (SE-AN) is a chronic eating disorder characterized by long-term starvation and its physical and psychological sequelae, and severe loss of quality of life. Interactions between neurobiological changes caused by starvation, vulnerability (personality) traits, and eating behaviors play a role. Several other factors, such as increased fear and decreased social cognition, have also been found in relation to SE-AN. With this in mind, we aim to add to the understanding of SE-AN by introducing the concept of mental capacity (MC), which refers to the ability to understand and process information-both on a cognitive and an emotional level-and then make a well-informed choice. MC may be an important construct within the context of SE-AN. Furthermore, we will argue how impaired decision-making processes may underlie, fuel, or contribute to limited MC in SE-AN. We will speculate on the importance of dysfunctional emotion processing and anxiety-related processes (e.g., a high intolerance of uncertainty) and their potential interaction with decision-making. Lastly, we will propose how these aspects, which to our knowledge have previously received little attention, may advise research and treatment or help in dealing with the "want but cannot" situation of life-threatening AN.

RESUMEN

Informed consent requires adequate mental capacity to consent to treatment. Mental capacity (MC) to consent to treatment refers to the ability to make medical decisions. MC is assessed in a general psychiatric interview, but this clinical assessment is known to overestimate mental capacity in patients and the inter rater reliability is low. The MacArthur Competence Assessment Tool for Treatment (MacCAT-T) has emerged as the gold standard to assess mental capacity to consent to treatment. The MacCAT-T is a semi-structured interview designed to aid clinicians in this assessment and has shown good inter rater reliability in patients with schizophrenia and other mental disorders, but has hardly been studied in patients with anorexia nervosa. Patients with anorexia nervosa (AN) regularly avoid treatment, even when severely ill and discussion includes assessing MC to consent to treatment. The aim of this study is to compare clinical judgment and the MacCAT-T in evaluating MC in patients with AN which in turn may influence use of the MacCAT-T in daily practice. In a sample of 70 consecutively referred severely ill patients with AN with a mean BMI of 15.5 kg/m2 and a mean duration of illness of 8.6 years, clinical assessment of MC by experienced psychiatrists and the outcome of the MacCAT-T interview were compared. Agreement (κ-value) was calculated. Agreement between clinical assessment and outcome of the MacCAT-T was questionable (κ 0.23). Unlike in other psychiatric populations, clinicians judged a high proportion of patients with AN as having diminished MC. The MacCAT-T can be useful in assessing MC in AN when used in addition to clinical judgment to aid clinicians in complex cases. Why clinicians judge a relatively high proportion of patients with AN as having diminished MC, in contrast to lower proportions in other psychiatric disorders, is an area in need of further research.

RESUMEN

BACKGROUND: Relevance of diminished mental capacity in anorexia nervosa (AN) to course of disorder is unknown. AIMS: To examine prognostic relevance of diminished mental capacity in AN. METHOD: A longitudinal study was conducted in 70 adult female patients with severe AN. At baseline, mental capacity was assessed by psychiatrists, and clinical and neuropsychological data (decision-making) were collected. After 1 and 2 years, clinical and neuropsychological assessments were repeated, and remission and admission rates were calculated. RESULTS: People with AN with diminished mental capacity had a less favourable outcome with regard to remission and were admitted more frequently. Their appreciation of illness remained hampered. Decision-making did not improve, in contrast to people with full mental capacity. CONCLUSIONS: People with AN with diminished mental capacity seem to do less well in treatment and display decision-making deficiencies that do not ameliorate with weight improvement.

RESUMEN

BACKGROUND: Mental capacity to consent to treatment in anorexia nervosa is a neglected area in clinical decision-making. AIMS: To examine clinical and neuropsychological parameters associated with diminished mental capacity in anorexia nervosa. METHOD: An explorative study was conducted in 70 adult female patients with severe anorexia nervosa. Mental capacity to consent to treatment was assessed by experienced psychiatrists. Further measurements included the MacCAT-T (to assess mental capacity status), a range of clinical measures (body mass index (BMI) and comorbidity) and neuropsychological tests assessing decision-making, central coherence and set-shifting capacity. RESULTS: Diminished mental capacity occurs in a third of patients with severe anorexia nervosa and is associated with a low BMI, less appreciation of illness and treatment, previous treatment for anorexia nervosa, low social functioning and poor set shifting. CONCLUSIONS: Assessment of diminished mental capacity in anorexia nervosa requires careful evaluation of not only BMI, but also the degree of appreciation of illness and treatment, history and the tendency to have a rigid thinking style.

RESUMEN

OBJECTIVE: Compulsory in-patient refeeding of patients with severe anorexia nervosa (AN) has caused considerable controversy. The effects of such treatment on longer-term outcome are not well known. The objective of this article is to review the evidence on the outcome of compulsory treatment for AN. METHOD: Three large databases were searched for studies regarding compulsory treatment in AN. RESULTS: Detained patients have more severe symptoms and comorbidity and a longer duration of inpatient stay. In the short term compulsory refeeding in AN appears to be beneficial, but the longer term effects remain uncertain. Clinicians report no worsening of the therapeutic relationship after compulsory treatment. DISCUSSION: In severe cases of AN where the patient refuses life-saving treatment compulsory treatment needs to be considered. Future research should focus on the longer term effects of compulsory treatment and also on questions related to mental capacity in AN.
