Right lower prefronto-parietal cortical dysfunction in akinetic catatonia: a combined study of neuropsychology and regional cerebral blood flow.
BACKGROUND Catatonia is a psychomotor syndrome that can be characterized by behavioural, affective and motor abnormalities. In order to reveal further underlying pathophysiological mechanisms of psychomotor disturbances in catatonia we investigated neuropsychological function and regional cerebral perfusion (r-CBF) in a combined study. METHODS Ten catatonic patients were investigated with Tc-...
متن کاملDecreased density of GABA-A receptors in the left sensorimotor cortex in akinetic catatonia: investigation of in vivo benzodiazepine receptor binding.
OBJECTIVES Catatonia is a psychomotor syndrome with concomittant akinesia and anxiety which both respond almost immediately to benzodiazepines such as lorazepam. The benzodiazepine receptor distribution was therefore investigated in akinetic catatonia with single photon emission tomography (SPECT) using iodine-123-iomazenil ((123) I Iomazenil). METHODS Ten akinetic catatonic patients, 10 psyc...
متن کاملEvaluation of regional cerebral glucose metabolism in patients with malignant lymphoma of the body using statistical image analysis
OBJECTIVES The aim of this study was to clarify the characteristics of regional cerebral glucose metabolic abnormalities in patients with malignant lymphoma of the body using statistical image analyses. Post-therapeutic changes in cerebral glucose metabolism were also evaluated. METHODS The subjects consisted of 30 patients, including 16 patients with diffuse large B-cell lymphoma and 14 pati...
متن کاملNeurobiological Approach of Catatonia and Treatment Perspectives
Catatonia was described for the first time by Kahlbaum in 1874 (1). It can be defined schematically as a motor dysregulation syndrome accompanied with a behavioral component. There are three main forms of catatonia: (i) akinetic, (ii) hyperkinetic, and (iii) malignant catatonia (2). These various phenotypes of the same syndrome led to a clinical heterogeneousness making the catatonia difficult ...
متن کاملOrbitofrontal cortical dysfunction in akinetic catatonia: a functional magnetic resonance imaging study during negative emotional stimulation.
Catatonia is a psychomotor syndrome characterized by concurrent emotional, behavioral, and motor anomalies. Pathophysiological mechanisms of psychomotor disturbances may be related to abnormal emotional-motor processing in prefrontal cortical networks. We therefore investigated prefrontal cortical activation and connectivity patterns during emotional-motor stimulation using functional magnetic ...
