How does cognitive flexibility relate to anorexia?

Previous research has shown that anorexia nervosa (AN) is associated with both weak cognitive flexibility and weak central coherence. These two factors have been incorporated in theoretical models of the development and maintenance of AN and are targeted in specific treatments for AN.

How does anorexia affect cognitive development?

Eating disorder patients often have persistent, obsessive thoughts about food, hunger, exercise, body shape and the like. It is possible that these thoughts “use up” some of their cognitive resources most of the time, leaving less ability to plan other decisions and perform other tasks.

What happens to the brain when you have anorexia?

Researchers have found that anorexia can have a bigger effect on brain structure than other mental health conditions like depression and OCD. The study suggested that people with anorexia are more likely to display reductions in three key measures of the brain, including surface area and thickness.

What is the cognitive model of eating Behaviour?

The cognitive theory of eating disorders posits that dysfunctional attitudes about physical appearance give rise to eating disorder risk factors such as dietary restriction, body dissatisfaction, and valuing of thinness.

What part of the brain is affected by anorexia?

Most fMRI studies performed in patients with anorexia nervosa focused on food, taste, physical appearance and social cognition. Although very different in terms of the study protocol, the most common findings are increased activation of the amygdala and altered activation of the cingulate cortex.

How does anorexia affect memory?

Directed-forgetting: individuals with eating disorders, particularly anorexia nervosa, display more difficulty in forgetting information or cues related to body, shape and food than those without eating disorders. This leads to greater availability of such memories, facilitating the maintenance of the eating disorder.

What is cognitive flexibility in psychology?

Cognitive flexibility, the readiness with which one can selectively switch between mental processes to generate appropriate behavioral responses, develops in a protracted manner and is compromised in several prevalent neurodevelopmental disorders.

How does being underweight affect the brain?

Being underweight also leads to low haemoglobin count in the blood. Haemoglobin is essential for carrying oxygen to the brain, and being low on this parameter results in poor oxygenation of the brain, leading to regular episodes of dizziness, easy fatigability and cognitive decline.

Does anorexia cause permanent brain damage?

Brain scans of people with anorexia reveal that the brain goes through structural changes or abnormal activity during the disease. Some of these abnormalities may discontinue weight restoration, but some of the damage to the brain can be permanent.

How does the brain impact eating behavior?

The brain is influenced by various signals to affect people’s eating behaviors and regulate their bodies’ energy balance, for example by changing appetite and energy expenditure in response to blood levels of key metabolic hormones and nutrients.

What is cognitive perspective?

Is anorexia a neurological disorder?

It is also proposed that bulimia consists of a “positive” neurological subtype and that restricting anorexia represents a “negative” neurological subtype.

What is the pathophysiology of anorexia?

Patients with anorexia nervosa have altered brain function and structure there are deficits in neurotransmitters dopamine (eating behavior and reward) and serotonin (impulse control and neuroticism), differential activation of the corticolimbic system (appetite and fear), and diminished activity among the …

What is anorexia brain fog?

Brain fog is considered to be a temporary mild cognitive impairment and sometimes thought of as an exaggerated mental fatigue. (1) Brain fog can occur in people with anorexia nervosa (AN), an eating disorder, as well as among people without this condition. A few common symptoms of brain fog include: reduced cognition.

What causes anorexia in the brain?

New research suggests that women who develop anorexia nervosa may have altered levels of dopamine in their brains. Dopamine disturbances can cause hyperactivity, repetition of behavior (such as food restriction), and anhedonia (a decreased sense of pleasure).

Can not eating cause brain damage?

The human brain operates at a very high metabolic rate, using a substantial portion of the body’s total energy and nutrient intake (Sarris et al., 2015). Without proper nutrition to fuel our brain transmission and function, our brain is left vulnerable (Altomare et al., 2017).

Changing the rules Previous studies have found that the prefrontal cortex is essential for cognitive flexibility, and that a part of the thalamus called the mediodorsal thalamus also contributes to this ability.

Does losing weight increase cognitive function?

Weight loss was associated with a significant improvement in attention and memory in both longitudinal studies and RCTs, whereas executive function and language improved in longitudinal and RCT studies, respectively.
