Attention Deficits in Minimal Hepatic Encephalopathy

Minimal hepatic encephalopathy (HE) is characterized by a decrease of psychomotor speed, and deficits in visual perception, visuo-spatial orientation, and visuo-constructive abilities. Attention deficits have ...

Correlations Between Cerebral Glucose Metabolism and Neuropsychological Test Performance in Nonalcoholic Cirrhotics

Many cirrhotics have abnormal neuropsychological test scores. To define the anatomical–physiological basis for encephalopathy in nonalcoholic cirrhotics, we performed resting-state fluorodeoxyglucose positron ...

Attention, Memory, and Cognitive Function in Hepatic Encephalopathy

Deficits in attention and arousal play a major role in the clinical presentation of hepatic encephalopathy. Attention deficits arealso the main components of minimal hepatic encephalopathy. The present paper s...
