Echoelectroencephalography is a non-invasive method for brain examination. Its main advantage is the ability to quickly diagnose diseases that lead to intracranial structure displacement. It also serves as a screening tool for preliminary diagnosis of brain space-occupying lesions and hypertension syndrome. It allows for high-precision differentiation of epilepsy from other pathological conditions.

EEG examines central nervous system function, diagnosing organic brain lesions and functional disorders of the nervous system.
