Abstract

The invention discloses a depression brain function connection change detection system and method based on a dynamic causal model. According to the system, the output terminal of a brain scanning module is connected with the input terminal of a data transmission module, the output terminal of the data transmission module is connected with the input terminal of a dynamic causality analysis module,and the output terminal of the dynamic causality analysis module is connected with the input terminal of a total processing module; the output terminal of the total processing module is connected withthe input terminal of the data transmission module, the output terminal of the data transmission module is connected with the input terminal of A diagnosis module, the output terminal of the diagnosis module is connected with the input terminal of a data output module; and the dynamic causal analysis module is adopted to analyze data; the dynamic causal model is adopted, the influence of depression on the connection change of the intracerebral function is discussed more deeply, and compared with a traditional analysis method, the analysis rate is increased, and the labor burden of medical workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of depression treatment, and specifically relates to a system and method for detecting brain functional connection changes in depression based on a dynamic causal model. Background technique [0002] Depression, also known as depressive disorder, is the main type of mood disorder with significant and persistent low mood as the main clinical feature. It can be seen clinically that the mood is not commensurate with the situation. The depression of mood can range from gloomy to distraught, low self-esteem and depression, even pessimistic world-weariness, and there may be suicide attempts or behaviors; even stupor; some cases have obvious anxiety and motor agitation; In severe cases, psychotic symptoms such as hallucinations and delusions may appear. Each attack lasts for at least 2 weeks, or even several years in the elderly. Most cases have a tendency to recur. Most of each attack can be relieved, and some ma...
