Perspectives for the Electroencephalogram in Psychiatry

Abstract

Perspectives for the Electroencephalogram in Psychiatry Abstract. The electroencephalogram (EEG) is a non-invasive and cost-effective method to monitor spontaneous neuronal activity over time. Pathologies in EEG recordings indicate with high sensitivity but low specificity abnormal functional brain states. The main psychiatric indications for EEG recordings include atypical clinical symptoms of a neuropsychiatric syndrome or atypical reactions to medication as well as a baseline diagnostic before starting treatment with specific drugs or stimulation modalities. In recent research the EEG continues to be a valuable tool not only in diagnostics but also for the prediction of treatment success. The following paper focuses on basic electrophysiological understanding of EEG recordings, the diagnostic value of EEG recordings in different clinical entities, and new research attempts in diagnostic and treatment prediction.
