What are the best treatments for Congenital Central Hypoventilation Syndrome?

Congenital Central Hypoventilation Syndrome (CCHS) is primarily managed through lifelong ventilatory support, such as mechanical ventilation or diaphragm pacing, to ensure adequate breathing, particularly during sleep. Because there is currently no cure, treatment focuses on stabilizing respiratory function and managing systemic complications through a dedicated multidisciplinary medical team.

What are the primary treatments for Congenital Central Hypoventilation Syndrome?

The cornerstone of management for Congenital Central Hypoventilation Syndrome is the provision of artificial ventilation. Because individuals with Congenital Central Hypoventilation Syndrome have an impaired autonomic nervous system response to carbon dioxide and oxygen levels, they cannot rely on their body’s natural drive to breathe. Most patients require tracheostomy-based positive pressure ventilation, especially in infancy and early childhood. As patients grow, some may transition to non-invasive ventilation (such as bi-level positive airway pressure) during sleep, though this is highly dependent on the severity of their specific PHOX2B gene mutation.

What non-pharmacological interventions are used?

Beyond standard mechanical ventilation, clinical management of Congenital Central Hypoventilation Syndrome often includes advanced surgical and rehabilitative options. A notable intervention is the surgical implantation of a diaphragm pacing system (such as the Avery Breathing Pacemaker), which stimulates the phrenic nerve to induce diaphragm contraction. This can provide patients with greater mobility and freedom from bulky ventilator tubing. Additionally, comprehensive supportive care is essential for long-term health:

• Physical and Occupational Therapy: To manage potential developmental delays and improve muscle tone.


• Speech Therapy: Often necessary for children who have had a tracheostomy, as it impacts vocalization and swallowing.


• Gastrointestinal Support: Many patients with Congenital Central Hypoventilation Syndrome experience Hirschsprung disease or severe dysmotility, requiring specialized dietary management or surgical intervention.


• Neuropsychological Support: To address the cognitive and behavioral impacts of chronic hypoxemia.

Which specialists should be on the care team?

Due to the multisystem nature of the condition, care for Congenital Central Hypoventilation Syndrome must be coordinated by a multidisciplinary team. This team typically includes a pulmonologist, a neurologist, a cardiologist (to monitor for sinus bradycardia and other dysrhythmias), and a gastroenterologist. Given the complexity of the condition, our 94 community members at DiseaseMaps.org emphasize the importance of having a primary coordinator who can synthesize recommendations from these various specialists to create a cohesive, personalized care plan.

Are there emerging treatments or clinical trials?

Current research into Congenital Central Hypoventilation Syndrome is focused on identifying pharmacologic agents that might stimulate the respiratory drive. While there are currently no FDA-approved medications that "cure" the underlying autonomic dysfunction, clinical trials have investigated the use of drugs like caffeine or almitrine to modulate the ventilatory response. However, these remain experimental and are not standard practice. Treatment effectiveness varies significantly between patients based on their specific genetic mutation, making personalized clinical assessment essential.

Next steps

• Consult a pediatric pulmonologist specialized in rare autonomic disorders to review your current ventilation settings.


• Connect with the 94 other members living with Congenital Central Hypoventilation Syndrome on DiseaseMaps.org to share experiences regarding equipment and daily management.


• Request a referral to a genetic counselor to discuss the specific PHOX2B mutation and its implications for family planning.


• Ensure your care team includes a cardiologist to perform regular EKG and Holter monitoring for heart rate variability.
