Background: Incidence of electroencephalography (EEG) changes rise in psychiatric patients due to psychiatric disorders itself and also due to psychotropic drugs with fugue symptoms between psychiatric disorders and neurological disorders. Objective: Evaluation of the EEG changes in patients admitted at Ahmed Galal Military Psychiatric Hospital. Patients and Methods: Two hundred and sixty adult male patients were studied by ICD psychometric assessment as symptom check list, socio – demographic assessment, semi – structural interview, and standard EEG. Results: Twenty patients have EEG changes, while other remaining two hundred and forty patients showed no EEG changes. From all patients having EEG changes, about 4.6 % (n=12) have grade I changes, and 3.1% (n=8) having grade II changes. Conclusion: EEG changes can help in psychometric assessment.
