Facial expression recognition in people with medicated and unmedicated Parkinsons disease.

Recognition of facial expressions of emotion was investigated in people with medicated and unmedicated Parkinsons disease (PD) and matched controls (unmedicated PD, n=16; medicated PD, n=20; controls, n=40). Participants in the medicated group showed ...

Dopaminergic modulation of visual-spatial working memory in Parkinsons disease.

Visual-spatial working memory (WM) impairment is frequently associated with the early stage of Parkinsons disease (PD). The aim of this study was to evaluate the performance of a group of PD patients in visual-spatial and visual-object WM tasks and to ...

Cognitive effects of the dopamine receptor agonist pergolide.

Although dopamine has been closely associated with prefrontal function, and with working memory in monkeys, the effects of dopamine agonists on human cognitive performance are poorly understood. We report the effects of a single dose of pergolide on ...

Nature of personal semantic memory: evidence from Alzheimers disease.

Personal semantic memory is factual knowledge about a persons own past. Although personal semantic memory is assumed to have features of both semantic memory and episodic memory, the relationship to episodic memory and to semantic memory have not been ...

Neuropsychological profile of patients with Parkinsons disease without dementia.

Cognitive deficits are often associated with Parkinsons disease (PD), although their prevalence in PD patients without dementia is still unknown. In order to describe the neuropsychological profile of PD patients without dementia, a sample of 103 PD ...

An investigation into age and gender differences in human Kamin blocking, using a computerized task.

Kamin blocking (KB) is a function within selective attention found to be deficient in schizophrenia. Disparate results in the KB literature, specifically regarding age and gender effects, suggest that we do not yet have a comprehensive understanding of ...

Objective assessment of the degree of dementia by means of EEG.

The aim of the study was to elaborate a method to estimate the degree of cognitive impairment in Alzheimers disease from the EEG quantitative indicators. We examined 38 unmedicated patients with a diagnosis of Alzheimers disease, with various stages ...

Perception of emotions from faces and voices following unilateral brain damage.

The importance of the right hemisphere in emotion perception in general has been well documented but its precise role is disputed. We compared the performance of 30 right hemisphere damaged (RHD) patients, 30 left hemisphere damaged (LHD) patients, and ...

Using executive heterogeneity to explore the nature of working memory deficits in Parkinsons disease.

Idiopathic Parkinsons disease (IPD) is characterised by a triad of motor symptoms, namely bradykinesia, rigidity and resting tremor, although cognitive impairment is a common feature of the disease and has been accepted as one of the strong predictors of ...

Social cognition in frontotemporal dementia and Huntingtons disease.

Frontotemporal dementia (FTD) and Huntingtons disease (HD) are degenerative disorders, with predominant involvement, respectively of frontal neocortex and striatum. Both conditions give rise to altered social conduct and breakdown in interpersonal ...
