Abstract

The invention provides a system for evaluating the degree of disturbance of consciousness, a recovery tendency prediction method, and a storage medium. The system includes a language generator configured to generate speech material that produces an auditory stimulus to a subject, an electroencephalogram measuring instrument configured to record electroencephalogram signals of the subject, and an analysis device configured to extract characteristic parameters from the electroencephalogram signals and obtain the degree of disturbance of consciousness of the subject according to the characteristic parameters. According to the system, bedside electroencephalogram can be adopted to evaluate the degree of disturbance of consciousness, use is convenient, the result is accurate, and the recovery tendency of a patient with disturbance of consciousness can be effectively predicted.

Description

technical field [0001] The invention mainly relates to the field of cognitive neuroscience, and in particular to a system for evaluating the degree of disturbance of consciousness, a recovery tendency prediction method and a storage medium. Background technique [0002] Exploring residual consciousness and cognitive abilities in unresponsive patients is one of the important clinical concerns and a major challenge in cognitive neuroscience. Every year, thousands of new patients lose their ability to communicate due to brain damage and fall into different states of clinical disturbance of consciousness, ranging from coma (Coma) to unresponsive wakefulness syndrome (Unresponsive Wakefulness Syndrome, UWS), and minimal consciousness ( Minimally Conscious State, MCS). The judgment of the degree of disturbance of consciousness of the patient's state is mainly based on the assessment of non-reflexive behaviors such as movement and speech movement at the bedside. During moments of...
