Routine 18-channel digital EEG was obtained to rule out any seizure activity or focal abnormalities. After more than 85 years of development and use in clinical practice, the electroencephalogram (EEG) remains a dependable, inexpensive, and useful diagnostic tool for the investigation of the electrophysiologic activity of the brain.

During this painless test, small sensors are attached to the scalp to pick up the electrical signals produced by the brain. A low-voltage electroencephalogram (LVEEG) is a record in which the amplitude of cerebral activity is below twenty microvolts over all head regions. By contrast, more widespread central nervous system (CNS) derangements, such as those due to metabolic disturbances, usually produce generalized EEG abnormalities. Epilepsy is a brain disorder marked by seizures, muscle spasms, and strange behavior or emotions. FINDINGS: Background rhythm during awake stage shows well . Electrographic abnormalities will be non-specific as to cause, although focal or lateralised changes can raise suspicion of encephalitis caused by herpes simplex infection (HSE).

Brain tumors Brain damage from head injury Brain dysfunction that can have a variety of causes (encephalopathy) Sleep disorders Inflammation of the brain (herpes encephalitis) Stroke Sleep disorders Creutzfeldt-Jakob disease An EEG might also be used to confirm brain death in someone in a persistent coma. Sharp waves are thought to be a result of synchronous activation of either a smaller group of neurons or neurons further away from recording electrode. The recordings will need to be analysed first and will be sent to the doctor who requested the test. Waves with a frequency of 7 Hz or less often are classified as abnormal in awake adults, although they normally can be seen in children or in adults who are .

A thorough understanding of a normal EEG is critical in defining those patterns that are abnormal. There has been considerable variability in the literature reported regarding EEG abnormalities in normal adult and epileptics using "hyperventilation test". An abnormal EEG means that there is a problem in an area of brain activity. Because EEG is unique in the ability to support a clinical diagnosis of epilepsy, epileptiform patterns merit careful consideration. The electrodes record the electrical activity of your brain, which shows up as wavy lines on an EEG recording. Both of these nutrients are critical in central nervous system function and when deficient can result in an abnormal EEG. . Stands out from the backgroundStands out from the background.
