Abstract:

Introduction:
One of the most disabling features and consequences of schizophrenia is marked impairment of social skills.
Aim of the work:
The aim of this study is to study the relationship between pre-morbid shyness and negative symptoms and resting frontal quantitative EEG alpha activity in schizophrenic patients.
Methodology:
Forty Schizophrenic patients were selected successively in a cross sectional study. The patients were assessed using The Structured Clinical Interview for DSM Axis of Disorders, Positive and Negative Syndrome Scale, The Revised Cheek and Buss Shyness and Sociability Scale. Quantitative EEG was done and assessed for frontal alpha asymmetry.
Results:
Ninety seven percent of patients showed asymmetrical frontal alpha EEG activity and 85% of them showed right resting frontal alpha EEG asymmetry. Patients with right frontal asymmetry showed higher scores in PANSS Negative and Shyness scores than left asymmetry.
Conclusion:
Negative symptoms of schizophrenia and pre-morbid shyness could be related to Right frontal resting alpha EEG asymmetry.
Key Words: Shyness, Negative symptoms, Schizophrenia, QEEG alpha asymmetry.
