Inclusion criteria

Inclusion criteria: All subjects, regardless of gender, aged 18-65, voluntarily participated in the project and met the requirements for each group. Informed consent was obtained from each subject before the study, and they signed an informed consent form. This study followed the principles of the Declaration of Helsinki. All subjects were divided into three groups: 1. Healthy Control Group (H group): 30 healthy volunteers were recruited in the Wuxi area, and saliva samples were collected from the volunteers; 2. OSA without cognitive impairment group (O group): Select 30 patients diagnosed with OSA by our hospital's doctors through polysomnography and assessed with the MoCA scale as having no related cognitive dysfunction. Collect saliva samples from the patients; 3. OSA with Cognitive Impairment Group (S group): 30 patients diagnosed with OSA by our hospital doctors through PSG and assessed to have cognitive impairment using the MoCA scale. Saliva samples were collected from these patients. Each cognitive function assessor was trained by a neurologist.
