Abstract
The pathophysiology of spasmodic torticollis is not clear. Basal ganglia dysfunction has been suggested to underlie this clinical syndrome. We studied resting cerebral glucose metabolism in 10 spasmodic torticollis patients and 10 healthy controls by using positronโemission tomography and [^18^F]2โfluoroโ2โdeoxyโDโglucose. Statistical parametric mapping (SPM95) was used to compare both groups on a pixelbyโpixel basis. Torticollis patients showed a significantly higher glucose metabolism bilaterally in the lentiform nucleus (p < 0.005). Analyses performed using normalization of regional to global glucose metabolism confirmed this finding (controls, 1.26 ยฑ 0.06, and patients, 1.35 ยฑ 0.06; p < 0.01). The torticollis score did not correlate with glucose metabolism, nor did disease duration or side of chin direction. Our results indicate that the lentiform nucleus plays a predominant role in the pathophysiology of idiopathic spasmodic torticollis.

## Abstract Single voxel proton spectroscopy was used to study brain metabolism in idiopathic spasmodic torticollis. Peak metabolite ratios in long echo time (135 ms) spectra were evaluated in the basal ganglia of 16 patients (29โ65 years). Eight of them were untreated; the other eight were examine
The intraperitoneal (IP) treatment of rats with diazinon (40 mg/kg) resulted in a variety of changes in the brain. Glycogen was depleted, but there was an increase in the activities of glycogen phosphorylase, phosphoglucomutase, hexokinase, lactate dehydrogenase, and fructose 1,6 diphosphatase. The
Clinical and histopathological findings hint at regional differences in the brain's sensitivity to metabolic changes in cirrhosis. The aim of the present study was to examine regional differences in cerebral ammonia metabolism in patients with cirrhosis and grade 0-to-I hepatic encephalopathy (HE).
