INTRODUCTION The growing interest in the cognitive impairment shown by patients with Parkinson's disease has led to a wealth of research in this line over recent years. In this paper we review the visuospatial alterations in these patients, which are usually linked to other disorders such as those affecting planning, sequencing, attention or mnemonic(More)
INTRODUCTION Cognitive reserve modulates between neurodegenerative processes and the clinical manifestations of cognitive impairment and dementia. This construct is associated with the capacity to optimise the execution of tasks by recruiting neuronal networks and with the use of alternative cognitive strategies that would be mediated by formal educational(More)
Disruption of prepulse inhibition of the startle response (PPI) has been widely identified in patients with schizophrenia, as well as impairment in many domains of cognitive functioning. However, there is some controversy regarding the relationship between PPI and the different neuropsychological tasks assessing inhibition. This controversy may be due to(More)
Cognitive deficits in schizophrenia have been widely reported. Neurophysiological and neuropsychological assessments have been conducted to study these impairments. Event-related potentials (ERPs) are relevant markers of cognitive deficits in schizophrenia, and reductions in specific ERP components have been found. The MATRICS Consensus Cognitive Battery(More)
Deficits in prepulse inhibition (PPI) and cannabis abuse are consistently found in schizophrenia. The authors studied PPI deficits in first episode psychosis (FEP) with schizophrenia and cannabis abuse influence. Thirty-five patients with FEP and 22 control subjects were examined. Patients were divided into cannabis use disorder (CUD) (N=21) and non-CUD(More)

Title: Executive control processes in Alzheimer's disease. Abstract: It has been recently proposed that executive control (EC) is composed by different subprocesses. In recent times, EC deficits in Alz-heimer's disease patients (AD) have been widely investigated. This analysis is very interesting because, on the one hand, recent studies have observed(More)
The current study examined the hypothesis that old people have a selective deficit in the identification of emotional facial expressions (EFEs) when the task conditions require the mechanism of the central executive. We have used a Dual Task (DT) paradigm to assess the role of visuo-spatial interference of working memory when processing emotional faces(More)

AIM There are various published studies showing that chronic alcoholics present cognitive deficit. In this conference we would like to review the most actual studies focusing on the neuropsychological alterations as consequences of the long and abusive alcohol intake. We also will analyse the involvement of these deficit in a complex task as driving. (More)
