Cerebral blood flow in thalamic aphasia.

A 59-year-old man is reported, who became aphasic after left thalamic infarction, shown by CT. His speech was fluent, with reduced voice volume, impaired auditory and reading comprehension, verbal paraphasias but intact repetition skills. A single photon emission computed tomography (SPECT) scan to measure regional cerebral flow (rCBF) showed a reduction of flow in the parietotemporal areas of the left hemisphere. It is suggested that thalamic aphasia could result from structural subcortical damage with a homolateral functional cortical deficit leading to the specific aphasic disturbance.

[Choreoathetosis. Uncommon manifestation during chronic liver disease with portocaval shunt]. / Coreoatetosi. Una manifestazione non comune in corso di epatopatie croniche con shunt porto-cavale.

"Acquired hepatocerebral degeneration" is a rare syndrome characterized by extrapiramidal symptomathology in patients affected by liver complaint with porta-cava shunt. Extrapiramidal symptomathology become chronical and progressive and its development is partially independent from the basic liver complaint. We report one case of "acquired hepatocerebral degeneration" whose clinical features lead us to advance a pathogenetic hypothesis on the role played by neurotransmitters in this syndrome.
