Identificación e interpretación de las ondas electroencefalográficas en pacientes con posibles trastornos neurológicos

Abstract

An electroencephalogram is a test that detects the electrical activity of the brain, brain neurons communicate through electrical impulses and are active all the time, even while you sleep, this information obtained through electroencephalography is very useful in clinical practice Hence the need to know in detail when this information is normal or abnormal, for this reason it is essential to know the waves that are generated in four bands: delta, Theta, Alpha and Beta, and to which area of the Brain they are linked to be able to determine patterns normal or abnormal, an EEG is able to determine changes in brain activity that can be helpful in diagnosing brain disorders, especially epilepsy or other seizure disorders, an EEG can also be helpful in diagnosing or treating disorders such as Brain tumor, Brain damage from injuries in the head, Brain dysfunctions that can Having various causes (encephalopathy), Inflammation of the brain (encephalitis), Stroke, Sleep disorders, an EEG may also be used to confirm brain death in a person who is in a persistent coma, even though early in the pandemic The usefulness of EEG in the recognition of neurological complications of SARS-CoV-2 infection was unknown, recent studies have provided diagnostic relevance of the specific patterns of abnormal brain activity that can be observed in these patients during the acute and subacute phase of COVID -19, the practice of EEGs can obtain important information for diagnostic and treatment purposes.
