Schizophrenic patients have higher smoking rates than the general population. Studies show that smoking may be a form of self-medication in an attempt to alleviate cognitive deficits in schizophrenic patients of European background. This study examined the relationships between smoking and cognitive deficits in Chinese schizophrenic patients, which have previously received little systemic study...

The aim of the present study was to examine spatial processing of facial emotion in schizophrenic patients suffering from affective symptoms. A face-in-the-crowd task using schematic stimuli was administered to schizophrenic patients with flat affect (n=30), schizophrenic patients suffering from anhedonia (n=30), schizophrenic patients not suffering from anhedonia or flat affect (n=28), and a g...

Background: We examined whether motor speed assessed by the finger tapping test predicts generalized and specific stable deficits because of a common pathogenic process in bipolar and schizophrenic patients. Methods: One hundred and two patients underwent a battery of neuropsychological tests. Patients with a score of less than one standard deviation from their siblings’ sample in two assessmen...

BACKGROUND Cognitive deficits in schizophrenia are regarded by many psychiatrist as an important symptom, which requires appropriate treatment and rehabilitation. There are different conditions, which may have an influence on cognitive impairment in schizophrenic patients. One the factors differentiating subgroups of schizophrenic patients when neuropsychological functioning is analyzed is sex....

Background: About 40%-60% of schizophrenic patients are resistant to ordinary treatment, which result from interference with different neurotransmitter systems in the process of disease. The aim of present study was to determine the effect of famotidine on several symptoms of schizophrenia which was nonresponsive to neuroleptic treatment. Methods: 30 schizophrenic patients previously nonrespons...

Objective: The aim of the present study is to assess information transmission between different cortical areas in schizophrenics by estimating the average cross mutual information (A-CMI) and to characterize the dynamical property of the cortical areas of schizophrenic patients from multi-channel EEG by establishing the auto mutual information (AMI). Methods: We recorded the EEG from 16 electro...

Psychophysiological anomalies in symptomatic schizophrenic patients, remitted schizophrenic patients, and individuals at heightened risk for a schizophrenic disorder are reviewed with an emphasis on electrodermal anomalies. Two electrodermal anomalies are identified in different subgroups of symptomatic patients: (1) an abnormally high sympathetic arousal and (2) an abnormal absence of skin con...

BACKGROUND The efficacy of antipsychotics can be evaluated using the dimensional models of schizophrenic symptoms. The D2/D3-selective antagonist amisulpride has shown similar efficacy and tolerability to other atypical antipsychotics. The aim of the present study was to determine the efficacy of amisulpride on the dimensional model of schizophrenic symptoms and tolerability in latin schizophre...

OBJECTIVE The level of various specific biomarkers of oxidative stress in plasma from schizophrenic patients, as well as biomarkers (the level of isoprostanes) in urine in schizophrenic patients was described. The aim of our present study was to evaluate biomarkers of oxidative stress by oxidative/nitrative modifications of plasma proteins (by measuring the level of carbonyl groups and 3-nitrot...

Controlling for possible treatment effects, medication, E bias, and constancy of fixation, schizophrenic patients were found to have a smaller figural aftereffect than a nonschizophrenic group. Earlier reports of displacement of the T figure toward the I figure in schizophrenic patients were confirmed. 10 of the 11 Ss who did not maintain constant fixation were schizophrenic patients. This find...
