Summary
Shared genetics influence attention-deficit/hyperactivity disorder (ADHD) and disordered eating in adolescents. Understanding these links is crucial for developing targeted prevention and treatment strategies for both conditions.
Area of Science:
- Psychiatry
- Genetics
- Developmental Psychology
Background:
- Bivariate associations between attention-deficit/hyperactivity disorder (ADHD) and eating disorders are known in adolescents.
- The underlying mechanistic link between ADHD symptoms and disordered eating requires further investigation.
Purpose of the Study:
- To evaluate shared genetic and environmental influences on ADHD symptoms and disordered eating in adolescent twins.
- To elucidate the specific genetic and environmental pathways contributing to the comorbidity of ADHD and eating disorders.
Main Methods:
- Utilized bivariate models on a Swedish twin cohort (TCHAD) comprising 819 females and 756 males.
- Analyzed common additive genetic and unique environmental effects on ADHD symptoms and disordered eating.
Main Results:
- Common additive genetic and unique environmental factors largely explained the associations between ADHD and disordered eating.
- In girls, genetic factors significantly correlated cognitive/inattention problems with bulimia (0.54, 67% of phenotypic correlation).
- In boys, strong genetic correlations were found for conduct problems-bulimia (0.54, 83%) and hyperactivity-bulimia (0.54, 95%).
Conclusions:
- Shared genetic factors play a significant role in the comorbidity of ADHD and disordered eating in both sexes.
- Findings underscore the necessity for integrated preventative measures and specialized treatments addressing ADHD and disordered eating concurrently.

145
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....

172
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

154
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...

01:30Bulimia Nervosa
178
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.
