About Juntendo University Hospital Sleep and Sleep-Disordered Breathing Center

Juntendo University Hospital's Sleep and Sleep-Disordered Breathing Center, located in the heart of Tokyo, Japan, stands as a beacon of excellence in the diagnosis and treatment of a wide array of sleep disorders. As a designated 'Special Functioning Hospital' by the Japanese Ministry of Health, Labor and Welfare, Juntendo University Hospital is committed to providing advanced, high-level medical care, and its Sleep and Sleep-Disordered Breathing Center is a testament to this commitment. The center is built on a foundation of multidisciplinary collaboration, bringing together a team of renowned specialists from various fields to offer patients a truly holistic and personalized approach to sleep medicine.

The center's core mission is to address the growing prevalence of sleep disorders, particularly sleep-disordered breathing, which includes conditions such as snoring, sleep apnea syndrome, Cheyne-Stokes respiration, and sleep-related hypoventilation syndrome. Recognizing the profound impact that sleep has on overall health and quality of life, the center's team of experts works tirelessly to diagnose and treat these conditions, helping patients to not only sleep better but also to mitigate the serious health risks associated with untreated sleep disorders, such as cardiovascular disease.

What truly sets the Juntendo University Hospital Sleep and Sleep-Disordered Breathing Center apart is its unique, collaborative approach to patient care. The center is led by a distinguished team of specialists, including Director Dr. Takatoshi Kasai, a leading figure in cardiovascular medicine and sleep research, and Vice Directors Dr. Tomomi Shioda (Respiratory Medicine) and Dr. Ayako Inoshita (Otorhinolaryngology/Head and Neck Surgery). This core team is further supported by a dedicated group of physicians, dentists, clinical laboratory technicians, and clinical engineers, all working in concert to provide the most comprehensive and effective care possible. This multidisciplinary team ensures that each patient receives a thorough evaluation and a treatment plan that is tailored to their specific needs and circumstances.

The center offers a wide range of advanced diagnostic and therapeutic services. For diagnosis, the center utilizes state-of-the-art technology, including in-hospital polysomnography (PSG) tests for a detailed analysis of sleep patterns and portable polygraphy tests that patients can use in the comfort of their own homes. Once a diagnosis is made, the center offers a variety of treatment options, including the gold-standard CPAP (Continuous Positive Airway Pressure) therapy, custom-made oral appliances (mouthpieces), and surgical interventions such as adenoidectomy and tonsillectomy, particularly for pediatric patients. Furthermore, the center is at the forefront of innovative treatments, offering cutting-edge therapies like Hypoglossal Nerve Electrical Stimulation Therapy for patients who are unable to tolerate CPAP, and Adaptive Servo-Ventilation (ASV) for those with central sleep apnea. This comprehensive suite of services ensures that every patient has access to the most appropriate and effective treatment for their condition.

In addition to its clinical excellence, the Juntendo University Hospital Sleep and Sleep-Disordered Breathing Center is also a hub of research and innovation in the field of sleep medicine. The center's physicians are actively involved in research to better understand the mechanisms of sleep disorders and to develop new and improved treatments. This commitment to research ensures that the center remains at the cutting edge of the field, offering patients access to the latest advancements in sleep medicine. With its unwavering commitment to patient care, its multidisciplinary team of experts, and its dedication to research and innovation, the Juntendo University Hospital Sleep and Sleep-Disordered Breathing Center is a world-class institution that is making a profound difference in the lives of people with sleep disorders.
