Acute and reversible Pisa syndrome as unusual presentation of portosystemic encephalopathy
2020
Abstract We present the first case of acute and reversible Pisa Syndrome, as a clinical manifestation of a portosystemic encephalopathy bout occurring in a patient affected with cirrhosis and clinical-radiological signs of acquired hepatocerebral degeneration, without exposure to psychotropic medications. A 62 year-old man suffering from cirrhosis was admitted to our hospital for sudden onset of mild confusion and postural change. He was observed walking and standing with a tilt toward the right during the last two hours. On neurological examination, he showed bilateral asterixis and extrapyramidal signs.

Amygdala-hippocampal atrophy and memory performance in dementia of Alzheimer type.
1997
The aim of the present study was to examine the involvement of brain structures, especially the amygdala-hippocampal complex, in dementia of Alzheimer type (DAT), and to assess the relation of amygdala-hippocampal atrophy with memory dysfunction. 14 patients with DAT and 10 healthy age-matched controls were examined with different neuropsychologic tests including the UCLA-Auditory Verbal Learning Test. MRI was performed with a conventional 1.5-tesla scanner. Atrophy was found in many brain structures of demented subjects in comparison with healthy age-matched controls. The volumes of amygdala-hippocampal complexes and of the temporal lobes of demented subjects were more reduced than the tot…
