Answer

Answer

For some time, electroencephalography (EEG) has been employed clinically as a measure of brain function in the hope of determining and differentiating certain functional conditions of the brain. It is used in patients with cognitive dysfunction involving either a general decline of overall brain function or a localized or lateralized deficit. This article primarily addresses the clinical use of EEG in the evaluation of dementias and encephalopathies. In addition, aspects of digital EEG and other newer developments are discussed briefly.
