Joint research on "SAS risk assessment using AI image diagnosis"

Project Goals


Brain Sleep is strengthening its collaboration with sleep specialists in order to promote solutions to the sleep problems of Japanese people. As a first step, the company has begun joint research with the Ota Sleep Science Center at Ota General Hospital Memorial Research Institute (hereinafter referred to as "Ota Sleep Science Center"), which boasts one of the largest numbers of SAS cases in the country, to develop an algorithm for determining the risk of sleep apnea syndrome (hereinafter referred to as "SAS")* using AI image diagnosis.
Through this joint research, we aim to help lead to appropriate treatment for SAS by focusing on "skeletal structure" in addition to "obesity" as a risk factor for SAS and proposing AI image diagnosis using facial photos taken with a smartphone, etc. Although there are many potential patients with SAS and it is a disorder with high health risks, it is not sufficiently recognized or treated, so we believe that raising awareness of SAS through this initiative will lead to the solution of sleep issues in Japan.

*Sleep apnea syndrome is a sleep-related breathing disorder characterized by repeated apnea and hypopnea during sleep. One of the diagnostic criteria is an apnea-hypopnea index (AHI), which is the combined number of apnea and hypopnea episodes per hour, of 5 or more.

Future outlook


By utilizing the results of this study, we hope to enable people to easily find out their own SAS risk via a browser or app, enabling them to receive optimal treatment and prevention.

Obesity is thought to be the main risk factor for SAS, but by showing the risk due to skeletal structure through this joint research, the researchers hope to raise awareness that SAS is a disease that even thin people can develop due to the small jaws that are a risk unique to Japan, and ultimately that it is a disease that anyone can develop, thereby aiming to solve Japan's sleep issues.
