The digital electroencephalogram has contributed to great advances in the diagnosis and follow-up of neurological diseases and ailments of conscience. This is because digital technology eliminates the need for stacks of paper for each EEG, facilitating graph analysis and archiving. The offer of the digital exam also allowed the development of EEG with brain mapping , a modern technique that enables the detailed study of brain electrical discharges, showing the areas where they occur. Hence the importance of understanding the applications, indications and types of report available for this test – which are the subject of this article. Continue reading to also learn about the differences between the analog electroencephalogram and the digital electroencephalogram, in addition to the advantages that telemedicine adds to the process. Shall we go ahead?
Digital electroencephalogram what is it?
Digital electroencephalogram is a type of EEG that eliminates the use of paper when issuing results, thanks to software that converts electrical signals into pixels (the smallest dots in a digital image). To explain better, it is important to know the meaning of the electroencephalography exam. It corresponds to a record of the brain’s electrical activity, generated by impulses that travel through the nerve cells of the brain (neurons) and spread throughout the body, commanding each activity performed. Which transforms them into line graphs that will interpret by neurologists. In addition to optimizing results in digital format. The test enables data sharing via a telemedicine platform and its remote interpretation. How does the digital electroencephalogram work? Digital EEG is simple, fast, painless, non-invasive and is part of the routine in several neurological diagnostic services.
As soon as the exam is schedule
Depending on the doctor’s request, he will also need to sleep a few hours the night before the procedure, to facilitate monitoring during sleep. On the day of the EEG, the patient removes cell phones, belts, jewelry and other items that may interfere with. The signal before entering DT Leads the exam room. Then, the doctor or technician. Who conducts the test positions you in a comfortable chair or stretcher and marks the points on the scalp where the electrodes will be attach. The professional applies an electrically conductive gel to the electrodes and places them on the patient’s scalp. Then, the EEG device , or electroencephalograph, is turned on and begins to amplify the signals emitted by the brain. The electrodes capture this activity and send the signals to specific software. Which converts them into digital images, showing different tracings.
