An eye movement analyzer suitable for testing cognitive impairment in epilepsy patients

Abstract

The invention discloses an eye movement analyzer suitable for testing of cognitive function lesions of an epileptic patient. The eye movement analyzer comprises a testing task generating system, an eye movement collecting system connected with the testing task generating system, an analyzing system connected with the eye movement collecting system, and a display system connected with the analyzingsystem. The testing task generating system comprises a basic data input module for inputting basic data of the patient, and a task list generating module; the basic data include epileptic patient identification and the initial cognition level for dividing the cognitive function lesions of the patient; the task list generating module generates a testing task list corresponding to the cognitive function lesions of the epileptic patient according to the initial cognition level; the eye movement collecting system conducts tracking sampling on eyeball movement according to the testing task list and transmits a sampling result to the eye movement analyzing system; and the analyzing system analyzes the sampling result and transmits an analyzing result to the display system; and the display system outputs and displays the analyzing result and corrects the initial cognition level according to the analyzing result.

Description

technical field [0001] The invention belongs to the field of cognitive evaluation, and in particular relates to an eye movement analyzer suitable for testing the cognitive impairment of epilepsy patients. Background technique [0002] Epilepsy is a chronic disease. Due to the special nature of the disease and the long-term application of antiepileptic drugs, patients often have varying degrees of cognitive dysfunction. Cognitive function is one of the important prognostic indicators of epilepsy. The assessment of the degree of cognitive dysfunction can not only be used to judge the prognosis and guide rehabilitation treatment, but also provide unified quantitative and comparable data for relevant clinical research work. The evaluation of cognitive function in patients with epilepsy has attracted more and more attention from clinical and scientific researchers. In 2011, the International League Against Epilepsy (ILAE) issued guidelines for the treatment of neuropsychological ...

Problems solved by technology

However, this test method has the following defects: testers need to have a professional background in neuropsychology, or have undergone relevant professional training to strictly control the objectivity of the test and reduce measurement errors; it is highly subjective; there is no uniform standard

There is a lack of evidence-based medical evidence in the current research on neuropsychological scales; most neuropsychological studies have serious methodological flaws in research design and test selection; some diseases are caused by patients with hearing or motor impairment. , cannot complete neuropsychological measurements or are not suitable for repeated assessment; neuropsychological scale assessments have limited sensitivity (such as the Wechsler memory scale); there are no (adequate) control conditions for the longitudinal study design, and it only analyzes group data without considering single result
