Problems solved by technology

[0005] At present, the application of eye-tracking technology to reflect the social cognitive impairment of patients with schizophrenia has limitations. These research materials are different from real scenes and cannot fully reflect the social cognitive level of patients in real scenes.
In addition, studies have confirmed that there is a compensation mechanism for the eye movements of schizophrenic patients in real scenes. Whether this compensation mechanism also exists in the eye movement patterns of social cognition, which leads to the difference between the eye movement recognition pattern and the face recognition pattern in social scenes, is unknown. research confirmed

Abstract

The invention discloses a schizophrenia diagnosis model, and the model is built through substituting an eye movement index in face emotion recognition and an eye movement index in emotion recognitionin a social scene into multivariate logistic regression analysis. The model provided by the invention can reflect the mental state of a tested person in a real scene, is more precise in diagnosis, andis suitable for the clinic popularization.

Description

technical field [0001] The invention belongs to the field of medical diagnosis and relates to a diagnosis model of schizophrenia. Background technique [0002] Schizophrenia is a group of unknown etiology, more common in young and middle-aged people, clinically manifested in many aspects such as thinking, perception, psychological disturbance and incoordination, emotion and behavior. The course of the disease is often protracted and recurrent. Most of the patients with a relatively long course have a decline in mental activity and deficits in social functions to varying degrees, which brings serious burdens to individuals, families and society. Calculated in terms of disability-adjusted life years, mental illness ranks first in the ranking of the total burden of disease in my country. According to WHO estimates, the burden of mental illness will rise to a quarter of my country's total disease burden by 2020. [0003] In the clinical work of psychiatry, the diagnosis of sch...
