Neuroscience | Eating Disorders

🍐 In this episode of PodBites, Mariam Gurashi and Aylin Nurioglu explore the complex world of eating disorders, connecting neuroscience, psychology, and clinical medicine to explain how disruptions in the brain’s reward system can lead to harmful eating behaviors and serious medical complications. 🎙️ Tune in to explore: How dopamine-driven reward pathways in the brain influence eating behavior and why food normally activates the VTA–nucleus accumbens reward circuit The role of the prefrontal cortex and stress hormones in impulse control and how cortisol can weaken decision-making during emotional stress Anorexia nervosa, including severe food restriction, distorted body image, and the life-threatening systemic effects of prolonged starvation The widespread complications of starvation, including amenorrhea, bradycardia, anemia, osteoporosis, and muscle wasting The dangerous metabolic shifts seen in refeeding syndrome, particularly hypophosphatemia during nutritional rehabilitation Bulimia nervosa, characterized by binge eating followed by compensatory behaviors such as vomiting, laxative use, or excessive exercise Classic clinical findings such as Russell’s sign, dental enamel erosion, and hypokalemia-related arrhythmias Binge eating disorder, where recurrent binge episodes occur without purging, often driven by emotional distress rather than hunger The link between binge eating and dopamine reward signaling, emotional triggers, and impaired impulse control Evidence-based management strategies including cognitive behavioral therapy, pharmacologic treatments, appetite-modulating medications, and metabolic interventions 🌟 A clinically grounded and neuroscience-informed guide to understanding eating disorders — helping learners recognize how brain circuits, emotional regulation, and medical complications intersect in these complex psychiatric conditions.
