Background: studies allowing to explore the neurobiological characteristics of the long-term schizophrenic process are of high significance for both clinical practice and biological psychiatry. Objective: to examine morphometric brain characteristics in chronic schizophrenia patients with different types of functional outcomes. Patients and methods: morphometric MRI characteristics of the cerebral cortex and subcortical structures are analysed in 46 patients with schizophrenia with a long disease durations (20.5 ± 6.7 years), and in 35 mentally healthy subjects matched by sex and age. Results and discussion: the whole group of patients showed decreased gray matter thickness in some cerebral cortex regions. When outcome was assessed using clinical-psychopathologic, clinical-catamnestic, and clinical-epidemiologic methods, bilateral increases in pallidum and putamen volumes were found to be a presumptive marker of worse functional outcome and remission poor quality. At the same time, when outcome was assessed on the basis of the current psychometric measures of social functioning and clinical symptomatology, patients with an unfavorable outcome were characterized by decreased gray matter thickness in the two cingulate cortex regions compared to both healthy controls and patients with a good outcome. However, the absence of correlations with clinical scales and functioning doesn’t allow a conclusion on the specificity of this decrease as a marker of outcome. Conclusion: the results may only presume beforehand the existence of different neuroanatomical subtypes (biotypes) associated with different functional outcomes in patients with chronic schizophrenia.
