Space exploration carried out under visual control and in its absence (blindfolded condition) was investigated in 20 RBD patients, 10 LBD patients and 20 normal controls with a modified version of Chedru's test (pressing the keys of a keyboard). Conventional tests for visual hemi-inattention permitted to classify RBD patients in a group with visual neglect(More)
We performed a postmortem morphometric study in six AIDS patients and six controls to determine if a neocortical neuronal loss occurs in HIV-1-associated cognitive/motor complex. Patients were selected during a prospective study including psychometric evaluation and neuroimaging, and none had focal lesions. Two had HIV-1-associated myelopathy with mild(More)
In a search task where four letters were displayed to the right of a central fixation point, right brain-damaged patients with visual neglect showed the fastest response when the target was at the rightmost position and progressively slower responses as it moved towards the center of the display. This finding confirms Kinsbourne's claim that in visual(More)
Neuropsychological deficits following mild head injury have been reported recently in the literature. The purpose of this study was to investigate this issue with a strict methodological approach. The neuropsychological performance of 50 mildly head injured patients was compared with that of 50 normal controls chosen with the case-control approach. No(More)
Extinction to the simultaneous presentation of sounds to both ears was investigated in patients with acute cerebrovascular disease and found to be present in nearly half of the patients in the early stage of stroke. The occurrence of the symptom was not significantly different following damage to either hemisphere, but a higher percentage of right(More)
Eight consecutive patients with CT scan evidence of a bilateral infarct in the territory of the paramedian thalamic artery are reported. In seven cases the infarct also extended to the territory of the polar artery. The main symptoms were: disorder of vigilance which cleared in a few days, and hypersomnolence which lasted longer and in two patients was(More)
Auditory neglect was investigated in normal controls and in patients with a recent unilateral hemispheric lesion, by requiring them to detect the interruptions that occurred in one ear in a sound delivered through earphones either mono-aurally or binaurally. Control patients accurately detected interruptions. One left brain damaged (LBD) patient missed only(More)
The pattern of preserved learning abilities is described in a severely amnesic patient after bilateral thalamic infarction. Experimental findings cannot be accounted for both by the view that only episodic memory is impaired in amnesia, while semantic memory is spared, and by the theory that what is spared in amnesia is procedural learning contrasted with(More)
Thirty-five patients and corresponding matched controls were investigated between 5 and 17 months from mild head trauma using the Self Rating Depression Scale and the State-Trait Anxiety Inventory. The findings indicate that compared with an appropriate control group mild head injured patients are at risk of developing depression, whereas their liability to(More)
Twenty five patients with peripheral neuropathy at different stages of human immunodeficiency virus (HIV) infection are reported. Cerebrospinal fluid (CSF) findings were available in 17 cases, electrophysiology in all and a neuromuscular biopsy in 11. Of six otherwise asymptomatic HIV+ patients, five had chronic inflammatory demyelinating polyneuropathy(More)
