Objective: Brain areas activated during pain can contribute to enhancing or reducing the pain experience, showing a potential connection between chronic pain and the neural response to pain in adolescents and youth.

Methods: This study examined changes in brain activation associated with experiencing physical pain and observing physical and emotional pain in others by using functional magnetic resonance imaging (fMRI) before and after intensive interdisciplinary pain treatment (IIPT). Eighteen youths (age 14 to 18) with widespread chronic pain completed fMRI testing before and after IIPT to assess changes in brain activation in response to physical and emotional pain.

Background: A majority of the people with multiple sclerosis (pwMS) experience sleep disturbances. Frailty is also common in pwMS. The geriatric literature strongly suggests that frailty is associated with worse sleep outcomes in community-dwelling older adults, but this association has yet to be explored among pwMS.

Weight loss interventions seldom include individuals with neurologic disease. The aims of the present study were to: 1) develop and assess the prefeasibility of a 6-month telehealth behavioral weight loss program for people with multiple sclerosis (MS) and obesity and 2) examine changes in weight loss (primary outcome), physical activity, and fruit/vegetable consumption at follow-up. Participants with obesity and MS engaged in a 24-week weight loss program.

We examined the neurocomputational mechanisms in which male adolescents make food and physical activity decisions and how those processes are influenced by body weight and physical activity levels. After physical activity and dietary assessments, thirty-eight males ages 14-18 completed the behavioral rating and fMRI decision tasks for food and physical activity items. The food and physical activity self-control decisions were significantly correlated with each other.

Approximately 3-10% of children have severe feeding issues, and some require enteral/tube nutrition to grow and thrive. For many children, tube feeding is temporary, making efficacious interventions for tube weaning essential. We conducted a systematic review and meta-analysis of tube weaning treatments.

The reinforcer pathology model posits that core behavioral economic mechanisms, including delay discounting and behavioral economic demand, underlie adverse health decisions and related clinical disorders. Extensions beyond substance use disorder and obesity, however, are limited. Using a reinforcer pathology framework, this study evaluates medical adherence decisions in patients with multiple sclerosis.

Background: Children's sensory processing patterns are linked with their eating habits; children with increased sensory sensitivity are often picky eaters. Research suggests that children's eating habits are also partially influenced by attention to food and beverage advertising. However, the extent to which sensory processing influences children's attention to food cues remains unknown.

The brain is the seat of body weight homeostasis. However, our inability to control the increasing prevalence of obesity highlights a need to look beyond canonical feeding pathways to broaden our understanding of body weight control. Here we used a reverse-translational approach to identify and anatomically, molecularly and functionally characterize a neural ensemble that promotes satiation.

This study explored risk parameters of obesity in food decision-making in mother-child dyads. We tested 45 children between 8-12 years and their biological mothers to measure the decision weights of food health attributes, the decision weights of food taste attributes, self-regulated food decisions, and self-reported self-control scores. Maternal body mass index (BMI), and children's BMI-percentiles-for-age were also measured.

Weight loss improves overall health, and reduces inflammation, risk of stroke, heart attack, diabetes, certain cancers, and death among individuals with obesity. Weight loss also improves mobility, increases stamina, and elevates mood. Between 25 and 33% of people with Multiple Sclerosis (pwMS) have obesity.

Children are vulnerable to adverse effects of food advertising. Food commercials are known to increase hedonic, taste-oriented, and unhealthy food decisions. The current study examined how promoting resilience to food commercials impacted susceptibility to unhealthy food decision-making in children.

Purpose Of Review: The goal of the current paper is to review the literature on the neural and behavioral factors involved in food decision-making in youth.

Recent Findings: Recent neuroimaging studies that employ passive viewing paradigms have found that exposure to food-related cues activate reward, motor planning, and attentional salience signals in children. Greater activations of reward signals and/or lower activations of control signals are associated with overeating and weight gain.

Multiple sclerosis (MS) is a neurodegenerative disorder that causes a wide range of symptoms, which, if left untreated, worsen over time. Despite the availability of effective medications, however, many MS patients fail to take their medications. One possibility is that these patients fail to follow through on treatment recommendations because they do not value these treatments-despite their effectiveness.

Greater ability to delay gratification for an immediate food reward may protect against the development of obesity. However, it is not known if the behaviors children exhibit during a delay of gratification task are related to overeating in other contexts. The purpose of this analysis was to assess the relationship between observed child coping strategies during a delay of gratification task and laboratory intake from ad libitum test-meals.

Behavioral economics has been consistently useful in describing a wide range of clinical phenomena, particularly in reference to behavioral excesses such as substance abuse, problematic gambling and obesity/overeating. Given an opportunity to explore these processes as they relate to treatment adherence in patients with multiple sclerosis (MS), our central thesis was that behavioral economic tools/processes that have been helpful in other areas of application (e.g.

Self-control is important for healthy eating. Achieving and maintaining healthy eating behaviors can be challenging for children. Susceptibility to palatable unhealthy foods with high sugar, fat, and/or salt is a biologically predisposed, dominant response that can hinder healthy eating decisions.

Food commercials promote snack intake and alter food decision-making, yet the influence of exposure to food commercials on subsequent neural processing of food cues and intake at a meal is unclear. This study tested whether exposing children to food or toy commercials altered subsequent brain response to high- and low-energy dense food cues and influenced laboratory intake at a multi-item, ad libitum meal. Forty-one 7-9-year-old children (25 healthy weight; 16 with overweight/obesity) completed five visits as part of a within-subjects design where they consumed multi-item test-meals under three conditions: no exposure, food commercial exposure, and toy commercial exposure.

Rationale: Patients weigh risks and benefits when making treatment decisions. Despite this, relatively few studies examine the behavioral patterns underpinning these decisions. Moreover, individual differences in these patterns remain largely unexplored.

Multiple sclerosis (MS) is an autoimmune disease that causes a range of problematic symptoms. These symptoms tend to get worse over time, causing substantial impairment in patient quality of life. Although many effective disease-modifying therapies (DMTs) exist that slow the course of MS, patients often do not choose to take them, which may be because these medications carry substantial risks of side effects, varying from mild to severe, while only decreasing the probability of future symptoms.

Television food advertising influences children's food choices. The attribute of "taste" drives children's food choices, and exposure to food commercials can increase the importance of "taste" when children make food decisions. The current pilot study explored whether food advertising literacy training influences children's food choices.
