INTRODUCTION Personality change due to head injury is one of the most prevalent neuropsychiatric posttraumatic disorders and causes significant impairment in familial, social or occupational functioning. OBJECTIVES To study the prevalence and clinical characteristics of personality changes secondary to severe closed head injuries, according to DSM-IV(More)
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)
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)
Sensory gating deficits are commonly found in patients with schizophrenia. However, there is still scarce research on this issue. Thirty-eight patients with first-episode psychosis (FEP) were compared to thirty-eight controls. A condition-test paradigm of event-related potentials (ERP), prepulse inhibition (PPI), and some specific tasks of the MATRICS(More)
BACKGROUND Essential tremor (ET) and Parkinson's disease (PD) are two of the most common movement disorders. Leaving aside their motor features, these two conditions share several non-motor features, including cognitive dysfunction and personality changes. However, there are few data comparing the cognitive and personality profiles of ET with PD. Here we(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)
INTRODUCTION Before initiating the planning of the neuropsychological rehabilitation program for a brain injured patient, it is necessary to make and comprehensive neuropsychological evaluation. This evaluation has to be oriented, not only to the scores obtained, but how cognitive processes are deteriorated. In this sense, it is very important to pay(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)
