OBJECTIVES To propose a neuropsychological study of the various aspects of self-consciousness (SC) in Alzheimer's disease. METHODS Forty-five patients with probable mild or moderate AD were included in the study. Severity of their dementia was assessed by the Mini Mental State (MMS). Fourteen questions were prepared to evaluate SC. RESULTS No(More)
The study explored executive dysfunction in Parkinson's disease (PD) by using the Hayling test (Burgess & Shallice, 1996) and verbal fluency tasks (VFTs). PD patients showed longer response latencies than controls in both parts of the Hayling test (Section A/automatic and Section B/inhibition). Patients and controls did not differ in the proportion of(More)
BACKGROUND Recent clinical and research reports suggest that the cerebellum may contribute to the modulation of higher cognitive functions. MATERIAL AND METHODS We included 15 consecutive patients with isolated cerebellar infarcts (4 superior cerebellar artery territory infarcts, 1 anterior inferior cerebellar artery territory infarct and 10 posterior(More)
Event-related potentials (ERPs) and reaction times were recorded in a semantic decision task with isolated word pairs. The two words in each pair had either a metaphorical semantic link or a non-metaphorical semantic link. The metaphorical semantic link implied familiar expressions. Two conditions without any semantic link were also used, where the two(More)
Typical amyotrophic lateral sclerosis (ALS) is described as a motoneuron disease which spared cognitive functions. Recent studies reported cognitive impairement associated with classical ALS. Gallasi and al. (1985) detect subtle cognitive impairement sparing memory in a population of 22 patients affected with sporadic motoneuron disease. Iwasaki and al.(More)
INTRODUCTION The aim of the present study was to investigate the origin of set-shifting deficits observed in Parkinson's disease (PD). METHODS Seventeen patients diagnosed as having idiopathic PD were compared with 15 control subjects. We used a task-switching paradigm, including two tasks (task A and task B) so that subjects were required to switch(More)
