Insular Cortex Function and Clinical Management

Core Functions and Clinical Implications

The American Thoracic Society recommends that patients with chronic dyspnea receive treatment that addresses both physiological and psychological aspects of the condition, as increased insular activation reflects heightened interoceptive awareness of respiratory discomfort 1, 2.
The American College of Chest Physicians suggests that opioids can reduce dyspnea by decreasing insular activation and modulating cortical processing of respiratory sensations, providing relief for patients with air hunger-type dyspnea 1, 4.
The National Institute of Mental Health indicates that the insula's role in emotional processing and interoception is altered in individuals with substance use disorders, contributing to impaired decision-making and increased risk of relapse 4.
The American Academy of Pediatrics recommends that clinicians consider the impact of early trauma on insular development and function, requiring trauma-informed approaches to manage related conditions 11.
The European Respiratory Society notes that decreased insular activation occurs in obstructive sleep apnea patients and those with congenital central hypoventilation syndrome, suggesting blunted respiratory sensation 1.

The American Heart Association suggests that the insula's role in encoding the urge-to-cough intensity and incoming sensory input from airways is crucial in managing chronic cough, and that treatment should address both physiological triggers and psychological impact 8, 3.
The National Institute of Neurological Disorders and Stroke indicates that the insula demonstrates hyperactivation during emotional processing in OCD, particularly the anterior insula and head of caudate, reflecting increased salience and arousal responses 9, 10.

The American Psychological Association recommends that clinicians validate somatic symptoms as real neurobiological phenomena rather than dismissing them as "psychosomatic", and consider that functional complaints may reflect altered insular processing even without identifiable peripheral pathology 1, 11.
The European Psychiatric Association suggests that addressing anxiety and fear that amplify insular activation and symptom perception is crucial in managing conditions like chronic dyspnea and cough, and that interventions should target both emotional regulation and somatic symptoms simultaneously 1, 8, 3, 11.
