The authors describe a patient who experienced the sudden occurrence of hemicorea-hemiballism on the left side of the body and the contemporary agnosia of it. An unenhanced CT-scan disclosed an ischemic lesion involving the head of the caudate nucleus and of the anterior limb of the internal capsule of the contralateral hemisphere. The authors discuss the(More)
Acute confusional states and agitated delirium are among the most common psychopathologic disorders in the elderly. However, they are rarely reported in the course of infarcts in the territory of the posterior cerebral artery. This study involving thirteen patients aged more than 65 years suggests that acute confusional states from posterior cerebral artery(More)
BACKGROUND Intragastric balloons have been proposed to induce weight loss in obese subjects. The consequences of the balloon on gastric physiology remain poorly studied. We studied the influence of an intragastric balloon on gastric emptying in obese patients. PATIENTS AND METHODS 12 patients were included in the study, with BMI (mean +/- SD) of 38.51 +/-(More)
Three right-handed subjects presented impairment of consciousness, paralysis of vertical gaze, aphasia and memory disturbances. Computed tomography scans showed low-density lesions in the paramedian areas of the left thalamus. Neuropsychological examination revealed a fluent aphasia in one patient and a nonfluent in two; all had paraphasias and(More)
The authors describe the case of three patients suffering from language disorder secondary to mesencephalo-thalamic infarcts. One of them showed the clinical features of transcortical motor aphasia, while the other two presented the typical pattern of the so-called "thalamic aphasia". The CT-stereotaxic method for lesion localization disclosed that the(More)
A retrospective analysis was carried out on 52 patients with CT-identified lacunar infarcts in order to identify possible risk factors. It was found that arterial hypertension, cardiac emboli and/or emboli from epiaortic vessels play a significant role in the genesis of lacunar infarcts. No preferential relationship was found between "small" lacunes and(More)
The authors report the cases of two patients with CT-documented paramedian mesencephalo-thalamic infarcts, showing language disturbances. The first patient showed a non fluent, transcortical motor-like aphasia, the other had a fluent but severely paraphasic language disorder. The CT study disclosed that it was the dorso-median thalamic nucleus that was(More)
We defined large striatocapsular infarcts as subcortical softenings of more than 20 mm in diameter involving the territories of the lateral and medial groups of lenticulostriate arteries. The aim of this study of 56 patients was to compare the clinical features and risk factors of these infarcts with those of cortical and lacunar infarcts. On the whole, our(More)
The authors report the cases of 2 patients with extensive brain calcifications after thyroidectomy, showing behavioral and cognitive changes suggesting a subcortical dementia syndrome. On the basis of clinical, neuroradiologic and SPECT features they discuss the role of the brain calcifications in the pathophysiology of associated cognitive disorders and(More)
We examined a 55-year-old right-handed woman showing transient coma, amnesia, mild right hemiparesis, vertical gaze impairment and aphonia without aphasia. CT-scanning revealed bilateral paramedian thalamic infarction in the territory of the thalamo-subthalamic paramedian arteries. Aphonia may occur as a consequence of thalamic lesions, but until now it has(More)
