Greetings

 

At Kayukawa Clinic, we care for individuals experiencing not only mental health symptoms such as insomnia, anxiety, loss of motivation, and depression, but also a wide range of sleep disorders, including hypersomnia, obstructive sleep apnea, restless legs syndrome, REM sleep behavior disorder, and delayed sleep-wake phase disorder.

As an appointment-based clinic, we place great importance on early diagnosis and timely access to appropriate testing and treatment. Our Sleep Medicine Department provides specialized evaluations, including electroencephalography (EEG), the Multiple Sleep Latency Test (MSLT), and home sleep apnea testing. These examinations are conducted by experienced technologists using high-quality electrophysiological testing methods.

We also offer second-opinion consultations for patients currently receiving treatment elsewhere. When necessary, we work closely with other medical institutions to address physical health conditions and provide comprehensive support for both mind and body.

Please do not hesitate to seek help. You do not have to face these concerns alone.
