After graduating from University of Tsukuba in 1982, I joined the Department Psychiatry at same university. Due to anti-psychiatry social movement and reports incidents involving violence against in-hospital patients psychiatric hospitals, associations Japan faced questions related ethical awareness, making it a challenging environment for conducting clinical research. For this reason, first ha...
Objective: There is evidence for differential executive function in Bipolar I Disorder (BID) and schizophrenia that may tend different cognitive deficits and abnormalities. The objective of this sudsy was to compare the executive function of BID and schizophrenic patients. Materials & Methods: We studied 50 patients with BID, and 50 with schizophrenia participants in outpatients' clinic of R...
Schizophrenia is a psychotic disorder characterized by delusions, hallucinations, negative symptoms, as well as behavioral and cognitive dysfunction. It is a pathoetiologically heterogeneous disorder involving complex interrelated mechanisms that include oxidative stress and neuroinflammation. Neurovascular endothelial dysfunction and blood-brain barrier (BBB) hyperpermeability are established ...
Clozapine remains the most effective agent for treatment-resistant patients with schizophrenia. Recently, treatment with clozapine has been linked to a number of metabolic disturbances, including weight gain, diabetes mellitus, and serum lipid abnormalities. Despite the potential risks of medical morbidities, clozapine continues to have a major role in the care of treatment-resistant patients w...
Schizophrenia subjects' smooth pursuit abnormalities may reflect a problem with perception of motion, although evidence comes primarily from reports using stimuli that differ from standard smooth pursuit stimuli (i.e. moving gratings or coherent dots). This study presented schizophrenia and healthy subjects with a forced-choice speed discrimination paradigm using smooth pursuit-like stimuli. Th...
Chromosome 22q11 deletion syndrome (22q11DS) is associated with elevated rates of schizophrenia and other psychoses in adulthood. Childhood morphologic brain abnormalities are frequently reported, but the significance of these and their relationship to the development of schizophrenia are unclear. We sought to delineate midline neuroanatomical abnormalities in nonpsychotic children with 22q11DS...
BACKGROUND Although schizophrenia has been associated with abnormalities in brain anatomy, imaging studies have not fully determined the nature and relative contributions of gray matter (GM) and white matter (WM) disturbances underlying these findings. We sought to determine the pattern and distribution of these GM and WM abnormalities. Furthermore, we aimed to clarify the contribution of abnor...
Diffusion tensor imaging study of the fornix in first episode schizophrenia and in healthy controls.
BACKGROUND The fornix is a compact bundle of white matter fibers that project from the hippocampus to the mamillary bodies and septal nuclei. Its association with memory, as well as with symptoms in schizophrenia, has been reported in chronic schizophrenia. The purpose of this study is to determine whether or not fornix abnormalities are evident at the onset of schizophrenia. METHODS Diffusio...
The results of multiple investigations indicate visual motion-processing abnormalities in schizophrenia. There is little information, however, about the time course and neural correlates of motion-processing abnormalities among these subjects. For the present study, 13 schizophrenia and 13 healthy subjects performed a simple motion direction discrimination task with peripherally presented movin...
