EEG is a commonly used clinical technique for assessing cerebral bioelectrical activity, employed to evaluate the functional state of the cerebral cortex and help identify the location of pathological changes. Clinically, EEG is frequently used in diagnosing conditions such as epilepsy, psychiatric disorders, and traumatic brain injury, as well as diseases like schizophrenia and bipolar affective disorder. Although EEG is considered a very safe procedure with no side effects, certain contraindications do exist. Patients with cranial injuries or scalp lacerations following brain surgery should avoid undergoing EEG. Additionally, individuals with convulsive episodes, psychological disorders, or organic or functional impairments such as deafness or blindness should not undergo this test.
It is recommended to undergo EEG examinations at正规 medical institutions to ensure accurate diagnosis. Before the examination, the head should be cleaned thoroughly to avoid interference with EEG results. During the procedure, patients should avoid emotional tension and maintain a relaxed and calm state of mind.
