Exclusion criteria

Exclusion criteria: 1)Participants with organic diseases or mental disorders that hinder cooperation in the examination; 2)Participants with abnormal mental status as indicated by psychological screening scales; 3)Participants unable to cooperate during 3D facial data collection; 4)Participants with incomplete questionnaire data; 5)Participants with a clear history of cerebral lesions or surgery or with conditions such as claustrophobia that make magnetic resonance imaging unsuitable; 6)Participants with congenital facial defects or severe postnatal facial alterations; 7)Participants who withdraw midway; 8)Participants unable to understand and cooperate with the examination; Participants meeting any of the above criteria will be excluded.
