For patients with sleep-related disorders we provide medical care services by physicians in cooperation with one another, with specializations in: Neuropsychiatry, Otorhinolaryngology-Head and Neck Surgery, Metabolic Medicine, Pediatrics, and Geriatrics and Hypertension.
We treat mainly outpatients with sleep-related disorders such as sleep apnea syndrome (adult and pediatric), hypersomnia (narcolepsy, recurrent hypersomnia, etc.), and parasomnias.
Patients undergo a medical interview and a questionnaire survey on subjective/objective symptoms, and are given blood tests, endoscopy (upper respiratory tract morphologic assessment), head MRI examination, and all-night polysomnography, if needed.


The Sleep Medical Center was formed in April 2006 as a functional unit; accordingly, it is not unified with the outpatient counter, and is not equipped with specialized facilities.
At present, sleep medical care services are provided in Pediatrics, Neuropsychiatry, Otorhinolaryngology-Head and Neck Surgery, Metabolic Medicine, Geriatrics and Hypertension, and the Division for Oral and Facial Disorders (Osaka University Dental Hospital).
Individual physicians perform various sleep-related medical services including lifestyle guidance, sleep hygiene guidance, and medication from the standpoint of their own specialty; CPAP treatment, oral appliance (mouthpiece), surgical treatment, and nutritional guidance are provided to patients with sleep apnea syndrome.


The Sleep Medical Center is composed of: Cardiovascular Medicine, Nephrology, Geriatrics and Hypertension, Metabolic Medicine, Respiratory Medicine, Otorhinolaryngology-Head and Neck Surgery, Dermatology, Neurology and Cerebrovascular Diseases, Neuropsychiatry, Neurosurgery, Anesthesiology, Pediatrics, Urology, Nuclear Medicine, and the Division for Oral and Facial Disorders (Osaka University Dental Hospital).

Considerations in referring your patients to the Sleep Medical Center

A physician (at a local medical institution) must make an appointment for a first consultation via the Social Service Department before a patient can have consultation. If you have any questions, contact the appropriate clinical section: Neuropsychiatry (all sleep-related disorders), Otorhinolaryngology-Head and Neck Surgery (sleep apnea syndrome), or Pediatrics (pediatric sleep-related disorders), or Geriatrics and Hypertension(sleep apnea syndrome).
