Traumatic brain injury (TBI) patients have working memory deficits and altered patterns of brain activation during this function. The evolution of the impairment has not been examined to date. This study investigated longitudinal changes in brain activation during a working memory task. Twelve patients with severe and diffuse TBI and ten healthy matched(More)
Working memory is frequently impaired after traumatic brain injury (TBI). The present study aimed to investigate working memory deficits in patients with diffuse axonal injury and to determine the contribution of cerebral activation dysfunctions to them. Eighteen patients with severe TBI and 14 healthy controls matched for age and gender were included in(More)
BACKGROUND Memory is one of the most impaired functions after traumatic brain injury (TBI). We used diffusion tensor imaging (DTI) to determine the structural basis of memory deficit. We correlated fractional anisotropy (FA) of the fasciculi connecting the main cerebral regions that are involved in declarative and working memory functions. METHODS Fifteen(More)
INTRODUCTION Patients with multiple sclerosis (MS) may have an impairment in their decision-making. Altered decision making is a known cause of functional impairment in daily living activities and in the patient's autonomy, negatively contributing to their quality of life. OBJECTIVE The current study assessed the decision-making capacity of patients with(More)
PRIMARY OBJECTIVE To determine the neuropsychological profile of persons with anoxic brain injury. METHODS AND PROCEDURES A retrospective study on a population of persons with anoxic brain injury admitted to a Brain Injury Unit (Institut Guttmann, Spain) from 1995-2003. The sample was divided according to physiopathological mechanisms in two sub-groups:(More)
INTRODUCTION Patients with moderate or severe traumatic brain injury (TBI) may show impairment in decision- making processes. The Iowa Gambling Task (IGT) has become a widely used neuropsychological research tool to investigate decision-making by simulating real-life decision-making in terms of uncertainty, reward, and punishment. OBJECTIVE Investigate(More)
OBJECTIVE To assess whether, following a right-hemisphere stroke, the combined administration of computer-based cognitive rehabilitation and right hemifield eye-patching in patients with visuo-spatial neglect is more effective than computer-based cognitive rehabilitation alone. METHODS Twelve patients were randomized into two treatment groups: a single(More)
INTRODUCTION Persons who have suffered brain damage can experience a wide range of cognitive, behavioural and emotional disorders. However, neuropsychological rehabilitation usually focuses, almost exclusively, on the cognitive deficits and pays very little attention to the emotional challenges associated with the psychological impact of the lesion. It is(More)
BACKGROUND Visuo-spatial neglect predicts longer hospitalization, poorer recovery of motor skills and greater functional limitation. The aim of the present study was to analyze whether the combined administration of computerized cognitive rehabilitation with right hemifield eye-patching in patients with left spatial neglect following a right hemisphere(More)
INTRODUCTION Tham and Tegner proposed the Baking Tray Task (BTT) as a fast simple assessment test for detecting spatial negligence. However, very few studies have examined its validity as a diagnostic test. AIM To analyse the diagnostic validity of the BTT by measuring its specificity and sensitivity in a sample of subjects with right hemisphere strokes.(More)
