Abstract
Approximately 64–68 % of EEGs in psychiatric patients can provide evidence of abnormal electrical activity (Hughes and John 1999). The issue is finding out what such deviations mean diagnostically and therapeutically. Other than an abnormality pointing to a medical condition like epilepsy or encephalopathy, most of the EEG changes described in both schizophrenia and affective spectrum disorders do not carry specific diagnostic value by today’s classification systems. Hence, the elucidation and characterization of sEEG abnormalities in both psychotic and affective disorders remain rudimentary and in need of much more systematized effort. As has now been mentioned few times, much work exploring EEG deviations in these disorders utilizing the power of computer analytic technology has been published and continues to expand. The focus of the current chapter is on sEEG deviations and possible significance as well as work that remains to be performed.
