Electroencephalography is a non-invasive method of monitoring the spontaneous electrical activity of the brain, which consists in analysing the record of changes in electrical potentials collected from the surface of the head. EEG examination facilitates differentiation of functional and organic brain disorders.
EEG is an important diagnostic method in patients with sleep disorders, in a coma, with epilepsy and after a head trauma. EEG may also be performed in patients with encephalitis, diagnosed neoplasms and after a stroke.
The indications for performing an EEG examination is the presence of symptoms of faulty brain function (e.g. tremors), head trauma and a history of neurosurgical procedures.
