Non Cerebral Activity in Patients of Schizophrenia: EEG Study.

Non Cerebral Activities (NCA) can mimic almost any kind of cerebral electrical activity and lead to serious misinterpretation if artefact periods remain in the recording. We focused on NCA detection in EEG of Patients with Schizophrenia. Out of 35 schizophrenia patients the presence of muscle and eye blink artefacts were higher in there percentages i.e. 86% and 92%. Fifteen patients (42.8%) reported as EEG of doubtful significance, which is higher in psychiatric patient’s then general population of epileptics.
