Description
Technical Field
The present application relates to the field of biomedicine, and more particularly to a system and method for mental state monitoring and treatment based on closed-loop feedback.
Background
The brain electrical signal is an important physiological parameter of human body, and is characterized by having higher time resolution. Electroencephalogram signals are one of the most important physiological signals for research in the field of brain science at present, and are widely applied to the field of diagnosis and treatment of mental diseases (such as depression), Alzheimer's disease, brain tumors and other diseases at present. Because the amplitude of the electroencephalogram signal is small and only has uV magnitude, the detection and signal processing become the current popular field. The prior art has a special device for detecting mental diseases by electroencephalogram acquisition.
At present, the treatment method of mental diseases mainly comprises drug treatment, physical treatment and psychological treatment, wherein the physical treatment is the most popular at present such as transcranial magnetic stimulation treatment, electroconvulsive therapy, acupuncture and moxibustion and the like, and the psychological treatment mainly comprises cognitive psychotherapy, behavior therapy and music therapy.
Transcranial magnetic stimulation therapy is a painless physical therapy method, and can achieve the effect of regulating mood by transmitting magnetic signals to penetrate through the skull, stimulate cerebral neurons, and excite or inhibit cerebral cortex functions. The prior art has special transcranial magnetic therapeutic apparatus for transcranial magnetic stimulation therapy.
Music therapy, formally called a discipline in the united states in 1944, is a young applied discipline, and relates to a large and complex discipline field, and a great deal of research shows that music can stimulate the central system of brain in charge of emotion to generate response so as to regulate and treat emotion.
However, the prior art device for mental disease detection and the mental disease treatment are separate and independent devices and have single functions. At present, the mainstream portable electroencephalogram acquisition equipment only has an electroencephalogram acquisition function, but does not have functions of emotion detection, mental assessment and the like; the medical transcranial magnetic stimulation therapeutic apparatus has two obvious defects, namely, low portability and difficult carrying, and does not integrate the functions of electroencephalogram acquisition, mental evaluation and the like, and in practical application, the detection and treatment of mental diseases can be completed only by two to three instruments; the mainstream music therapy equipment is bulky and is generally a chair massage type equipment. The treatment equipment has the common characteristics of simple treatment, incapability of detecting the intervention treatment effect in real time, incapability of accurately adjusting the intervention treatment parameters in time and capability of spending a great deal of energy on hospital evaluation for treatment results. In summary, the existing electroencephalogram detection, mental state assessment, physical and psychological treatment means and the like are single-soldier combat, a comprehensive system integrating monitoring and treatment is not formed, and the actual experience of a patient is poor.
