Slow waves are brain waves detected by electroencephalogram examination, which may be normal or not, depending on the patient's age, the brain location in which they occur, and the existence of other related signs and symptoms.
The electroencephalogram (ECG) is the test that detects, through electrodes placed on the scalp with a conductive gel, the beta, alpha, theta and delta brain waves, and their variations in relation to the period that occur, frequency, amplitude and length of wave. Method (drowsiness, photostimulation, hyperpnea) is used during the ECG exam, which causes the brain to function differently, allowing the identification of changes.
Slow wave surges can occur in childhood, old age, and some forms of epilepsy. Their isolated presence does not mean that there is a disease or that some kind of treatment is necessary.
The neurologist and the neuropediatrician are the specialists to be consulted in these situations.
