Problems solved by technology

Most studies show that schizophrenic patients have search strategy limitations in saccadic pathways, namely shorter saccadic paths, decreased fixation with increasing duration, and avoidance of obvious visual characteristic stimuli, especially in facial emotion recognition.
[0007] At present, some researchers believe that the diagnostic value of a single eye movement paradigm is unstable, and the research trend is to use a combination of several paradigms to distinguish schizophrenia patients from normal people

Abstract

The invention provides a diagnosis index, a diagnosis model and a diagnosis system for schizophrenia. The diagnosis model comprises four key diagnosis indexes of fixed-point staring skewness peak time, face region fixation time, face region entering times and face region first fixation point fixation time. Compared with the prior art, the diagnosis model has the advantages that the diagnosis accuracy of schizophrenia is greatly improved, and a treatment scheme can be better formulated clinically.

Description

technical field [0001] The invention belongs to the field of disease risk prediction, and relates to a diagnostic index, a diagnostic model and a diagnostic system for schizophrenia. Background technique [0002] Schizophrenia is a chronic and highly disabling severe mental illness. Patients may present with hallucinations, delusions, speech disturbances and other negative symptoms combined with psychotic symptoms and poor thinking, and have obvious symptoms such as decreased memory and processing speed. Cognitive impairment, which affects nearly 1% of the world's population, is one of the top ten causes of disability worldwide. Although drug treatment can alleviate the symptoms of psychosis, the treatment effect is not good. About 20-30% of patients are ineffective to drugs, 35% will relapse after treatment, and 55% will have lifelong symptoms. At present, the diagnosis of schizophrenia mainly relies on explicit mental symptoms, and the sensitivity and specificity of objec...
