Abnormal photic driving responses in never-medicated schizophrenia patients.
The present study was conducted to compare electroencephalogram (EEG) driving responses to 10 hertz photic stimulation in 14 drug-naive schizophrenia patients and 16 sex- and age-matched control subjects. The amplitude of photic driving responses (PDRs) recorded from the occipital region was significantly lower in schizophrenia patients than in controls. In eight schizophrenia patients (vs. non...
متن کاملThalamic and prefrontal FDG uptake in never medicated patients with schizophrenia.
OBJECTIVE Because neuroleptic treatment may cause long-lasting changes in brain structure and function, a group of patients with schizophrenia who had never been medicated was recruited to examine regional glucose metabolic rates in the frontal-striato-thalamic circuit. METHOD Twelve never medicated patients with schizophrenia (seven men, five women; mean age=29 years) and 13 normal volunteer...
متن کاملChildhood Laryngeal Dystonia Following Bilateral Globus Pallidus Abnormality: A Case Study and Review of Literature
Introduction:Dystonia is a disorder of movement caused by various etiologies. Laryngeal dystonia is caused by the spasm of laryngeal muscles. It is a disorder caused by vocal fold movement in which excessive adduction or abduction of the vocal folds occurs during speech. The pathophysiology of this type of dystonia is not fully known. Some researchers have suggested that basal ganglia structure...

متن کاملSpecificity of prefrontal dysfunction and context processing deficits to schizophrenia in never-medicated patients with first-episode psychosis.
OBJECTIVE Context processing is a cognitive construct associated with activity in the middle frontal gyrus. Schizophrenia-related deficits in context processing tasks have been associated with prefrontal cortical dysfunction. This study evaluated whether prefrontal cortical dysfunction related to context processing occurred in first-episode, never-medicated schizophrenia patients, whether this ...
