Psychosis is a known feature of many psychiatric, neuropsychiatric, neurologic, neurodevelopmental, and medical conditions.
Highlight: prevalence of EEG changes was 28.6% while those without EEG changes was 71.4%.
only 4.3%had mild EEG changes,4.3 % had moderate abnormalities, 20.0 %of participants had severed abnormalities.
There was significant association between residence, marital status, educational level, patient status, duration of disease, No suicidal ideation and psychological trauma and EEG changes.
Objectives:
1-To assess the role of EEG in three of the most common psychotic disorders (schizophrenia, bipolar 1 disorder, major depression).
2-To determine if there are any abnormal EEG changes in these disorders.
3- To clarify the types of these changes if any.
4-To estimate the prevalence of these changes if any.
Method: observational cross sectional study was conducted on 70 patients with psychosis, 46 males and 24 females ,27 schizophrenia ,18 psychotic depression, 25 bipolar1disorder.Their age ranged from(18-50 ) from 1st of September 2019 to 1st of October 2020 in Merjan medical city Neurophysiology department , EEG was done to all patients in quite room with 10/20 system of electrode placements in which a 21 electrodes placed at the scalp .
The result: showed that the prevalence of EEG changes was 28.6% while those without EEG changes was 71.4%, only 4.3%had mild EEG changes,4.3 % had moderate abnormalities, 20.0 %of participants had sever abnormalities, There was significant association between residence, marital status , educational level ,patient status, duration of disease, No suicidal ideation and psychological trauma and EEG changes. Also, there was significant association between medication use and EEG changes. (X2=11.557, P=0.003*).
