We know, be careful before the area is not timely, ekg;The stomach is not timely, should undertake gastroscopy;And when the head is not timely, sometimes doctors will be the examination of the electroencephalogram (eeg) to you.The human brain has 14 billion brain cells, including 250 million nerve cells.Nerve cells activities can produce a variety of biological electrical signals, electroencephalogram (eeg) is using electroencephalograph recorded human brain bioelectric information.As long as the eeg machine probe electrodes on the scalp, the instrument can receive potential changes in the brain electrical activity in the process, then scanning pen is in the moving depicted on the drawings of various curve.Due to the different frequency and amplitude of curve, constitutes a different waveform, formed the eeg waves.Generally speaking, everyone has its inherent characteristics of eeg.Eeg rhythm of slow wave and fast activities, under normal physiological conditions, with a normal circadian rhythms and inherent characteristics, the eeg abnormalities, and indicates that has the potential of lesions.Therefore, in the physiological functions of evaluation on the brain, electroencephalography (eeg) examination.Because of lack of traumatic electroencephalography (eeg) is a kind of examination method, so can be repeated many times to check.What disease need electroencephalogram checks?

Mental illness: (1) for the diagnosis of schizophrenia and manic depression, mental disorder, etc., can do eeg examination, rule out other brain diseases, including epilepsy.

(2) : epilepsy due to epilepsy electroencephalogram (eeg) in attack can accurately record the scattered slow wave and spike wave or irregular spike wave, therefore in diagnosis of epilepsy and eeg examination is very accurate.

(3) some substantial lesions in the brain: some brain tumor, brain metastatic carcinoma and brain hematoma, often cause varying degrees of electroencephalogram (eeg) changes.The eeg change, according to the location and nature of the lesion, the stage and the damage situation, can appear jacksonian slow wave, the jacksonian slow wave, can diagnose lesions in the brain.

Eeg examination is a kind of inspection on brain function change of the effective methods, due to the changes of brain function is dynamic, changeable and so on?Some clinical patients with brain dysfunction performance in an electroencephalogram (eeg) inspection found no abnormalities, cannot be completely ruled out the existence of brain diseases, and shall be regularly reviewed electroencephalography (eeg), can be accurately found disease.

In addition, in the examination of the electroencephalogram (eeg), prior to shampoo, to keep them clean on the surface of the head, to the normal conduction current.When the inspectors come into contact with the scalp, don't be nervous, be gentle breath, cooperate with the doctor, completes the electroencephalogram (eeg) examination.
