Eeg is through the eeg machine tracer will own weak bioelectricity of record as a graph, in order to help diagnosis of a modern auxiliary examination method, it has been the checker without any trauma.Eeg in the diagnosis of brain disease have a certain value, but is limited by a variety of conditions, so most of the time not only as a diagnostic basis, requires a combination of patients with symptoms, signs and other experimental examination or auxiliary examination to comprehensive analysis.Electroencephalogram (eeg) is mainly used for intracranial organic lesion such as epilepsy, encephalitis, brain trauma, brain tumor.
Yantai industry of special survey of hospital expert introduction, electroencephalogram (eeg) is the most important auxiliary examination method in the diagnosis of epilepsy, clinical many diseases, such as apnea, movement disorders, syncope, arrhythmia, sleep disorder, slant headache and various kinds of neurosis, sometimes is very much like a seizure, with eeg examination, we often can make an accurate diagnosis.And electroencephalogram (eeg) for the choice of the antiepileptic therapy, dosage adjustment, stop treatment indications aspect also has certain reference significance, at the same time help to estimate the prognosis of epilepsy.Close analysis of the electroencephalogram (eeg) can help doctors determine the specific type of seizure, in order to select the correct and reasonable treatment, help to determine the effect of antiepileptic therapy.
Patients should be done before the expert reminds, inspection is as follows: 1, wash hair, don't rub oil, lest affect inspections;2, feast, in case of low blood sugar impact results;3, 3 days prior to check out all kinds of drugs, can't stop to medicines, dosage and usage, so that the doctor's reference.Check request when patients spirit is loosened, muscles relax in order to avoid electrical interference, and open and close according to the requirements of the doctor or hyperventilation.For the febrile convulsion, had better be in symptoms stop eeg examination in 10 days.In tetanic convulsion period of people with epilepsy, because of the large muscle electrical interference, should first for clinical treatment, convulsion in stable after eeg examination again.
Eeg examination results were divided into normal electroencephalogram (eeg) and abnormal electroencephalogram (eeg) two kinds, which can be divided into the mildly abnormal eeg abnormal electroencephalogram (eeg), moderately abnormal eeg, 4 severely abnormal electroencephalogram (eeg) three.Pediatric brain tissue is increasingly mature, so its normal electroencephalogram (eeg) and growth because of the age and no clear boundaries.Childhood eeg background activities by age and developmental level, record state a variety of factors, such as abnormal degree is difficult to grasp, and most closely relationship with brain damage not, hierarchical diagnosis and prognosis of the clinical evaluation condition without too much help, and likely to cause misunderstanding, clinicians and patients generally does not carry on abnormal electroencephalogram (eeg) children light, medium and severe classification.
Electroencephalogram (eeg) were the major influencing factors of age, individual differences, consciousness, stimulation, mental activity, drug effect and brain diseases, etc.Most clinical drug on brain function will directly or indirectly influence, especially the direct effect of the central nervous system drugs can cause obvious changes in brain waves.Specific changes and individual differences, drug kinds, medication method, quantity, etc.Such as beginning and increase dosage, brain waves change occurs, some after discontinuation of brainwaves change still persist in the short term, can appear even bounce phenomenon and see brain waves, it is also a clinical treatment of epilepsy can't suddenly stop drug or treatment
