Research Abstract

Existing operational diagnostic systems for major psychiatric disorders such as schizophrenia are based solely on clinical manifestations and associated psycho-social impairments. Because the laboratory measurements of the brain are stable relative to clinical manifestations, structural and functional neuroimagings might provide additional information to psychiatric diagnostic systems for more valid classifications. Tb identify the correlative pattern of neuro-physiological brain activity and gray matter distribution those best discriminate schizophrenia patients from healthy subjects, we applied discriminant function analysis techniques using the multivariate linear model and the low-resolution brain electromagnetic tomography (LORETA) and the voxel-based morphometry (VBM). These studies dose not revealed significant correlative pattern of LORETA neuro-physiological activity as well as VBM gray matter distribution. Obtained results can discriminate between the male patients with schizophrenia and the male control subjects. These patterns allowed favorable classification of subjects into different groups. Further elaboration of the present method may contribute to the clinical diagnosis of schizophrenia in the future.
