Summary
Binge-eating in eating disorders (EDs) is linked to self-reported attention difficulties, but not objective deficits. Anorexia nervosa binge/purge subtype (AN-B/P) shows sustained attention deficits.
Area of Science:
- Psychiatry
- Neuroscience
- Clinical Psychology
Background:
- Eating disorders (EDs) are complex mental health conditions.
- Attentional deficits are frequently observed in individuals with EDs.
- The relationship between binge-eating behavior and attention requires further clarification.
Purpose of the Study:
- To investigate the association between binge-eating behavior in ED patients and attentional deficits.
- To differentiate between subjective and objective measures of attention in EDs.
- To explore attention functioning across different ED subtypes.
Main Methods:
- Study included ED patients with binge-eating (n=51), without binge-eating (n=59), and controls (n=58).
- Attention was assessed using ADHD diagnosis, self-report questionnaires (ASRS, ADHD-RS), and neuropsychological tests.
- Eating pathology, depression, anxiety, and obsessionality were also monitored.
Main Results:
- Binge-eating ED patients reported more ADHD symptoms on the ADHD-RS compared to non-binge-eating patients.
- No significant differences in ADHD diagnosis or neuropsychological functioning were found between binge-eating and non-binge-eating groups.
- Anorexia nervosa binge/purge subtype (AN-B/P) exhibited the highest ADHD symptomatology and sustained attention deficits.
Conclusions:
- Binge-eating in EDs is associated with self-reported attentional difficulties (ADHD-RS), not objective neuropsychological deficits.
- Objective sustained attention deficits were specifically identified in the AN-B/P subtype.
- Findings highlight the importance of distinguishing between subjective and objective attention measures in ED research.

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.

A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...
