Educational action in the rehabilitation of severe acquired brain injuries: the role of self-awareness.

Severe acquired brain injuries (ABI) cause a range of short-or long-term limitations in physical and neuropsychological abilities. The aim of rehabilitation is to promote the harmonious development of the individual through collaboration between medical and educational sciences, involved in the educability of the whole person, in which the aim is not only functional recovery but also social-reintegration. This "functional synergy" permits the development of the person, and establishes an indissoluble link between functions and attitudes, thus allowing the achievement of the greater possible autonomy. In this way classical and pedagogical rehabilitation may be combined in a single concept of educational action. To realize this integrated educational process it is important to evaluate and promote awareness development, based on the possibilities of brain plasticity and on the presence of multiple intelligences skillfully intertwined each other. Therefore, self-awareness plays a prime role in educational actions for the rehabilitation of persons with severe ABI.

Quality of life after brain injury (QOLIBRI): Italian validation of the proxy version.

To validate the proxy version of the Quality of Life after Brain Injury (QOLIBRI) questionnaire to utilize caregivers for comparison and to evaluate the correspondence between patients' self-perceived and caregivers' perception of patients' Health-Related Quality of Life (HRQoL). Ninety-two patients with severe TBI and their main caregivers were enrolled. Patients' and caregivers' HRQoL was assessed by the Patient-QOLIBRI (Pt-QOLIBRI) and the Proxy-QOLIBRI (Pro-QOLIBRI), respectively. The Pro-QOLIBRI is a modified version of the QOLIBRI to investigate caregivers' perception of patients' HRQoL (Pro-QOLIBRIpatient-centered), and their degree of satisfaction and botheredness (Pro-QOLIBRIcaregiver centered). The patients' disability and their social reintegration was investigated by means of Glasgow Outcome Scale Extended and Community Integration Questionnaire. Pro-QOLIBRI has good internal consistency and homogeneity. There was also positive correlation between the level of satisfaction measured by Pro-QOLIBRI but not by Pt-QOLIBRI, and the disability severity and social integration of the patients. The comparison between the Pt-QOLIBRI and Pro-QOLIBRI confirmed the usefulness of the Pro-QOLIBRI, especially the caregiver-centered version, to predict the social reintegration of survivors. To our knowledge this is the first study that correlates the HRQoL of survivors, as self-perceived and as perceived by the caregivers with social reintegration.

Quality of life in persons after traumatic brain injury as self-perceived and as perceived by the caregivers.

The primary aim of the study was to adopt QOLIBRI (quality of life after brain injury) questionnaire in a proxy version (Q-Pro), i.e., to use caregivers for comparison and to evaluate whether TBI patients' judgment corresponds to that of their caregivers since the possible self-awareness deficit of the persons with TBI. A preliminary sample of 19 outpatients with TBI and their proxies was first evaluated with the Patient Competency Rating Scale to assess patients' self-awareness; then they were evaluated with the QOLIBRI Patient version (Q-Pt) and a patient-centered version of the Q-Pro. Subsequently, 55 patients and their caregivers were evaluated using the patient-centered and the caregiver-centered Q-Pro versions. Q-Pt for assessing Quality of Life (QoL) after TBI, as patients' subjective perspective and Q-Pro to assess the QoL of patients as perceived by the caregivers. The majority of patients (62.2%) showed better self-perception of QoL than their proxies; however, patients with low self-awareness were less satisfied than patients with adequate self-awareness. Low self-awareness does not impair the ability of patients with TBI to report on satisfaction with QoL as self-perceived.

Theory of mind impairment after severe traumatic brain injury and its relationship with caregivers' quality of life.

PURPOSE: Theory of mind (ToM) deficits are common consequences of severe Traumatic Brain Injury (sTBI), but little is known about their impact on patients' and their caregivers' quality of life. This study aimed (i) to examine the presence of ToM difficulties in individuals with sTBI and adequate levels of self-awareness (SA); (ii) to investigate their relationship with perceived Health Related Quality of Life (HRQoL) in patients and their caregivers. METHODS: Twenty individuals with sTBI and adequate levels of SA, and 20 healthy controls (HCs) were recruited. ToM was examined by the Faux-pas Recognition paradigm. The QOLIBRI questionnaire was administered to patients and their caregivers to assess their HRQoL. Cognitive functioning and psychopathology were evaluated. RESULTS: Individuals with sTBI were less accurate than HCs on the Faux-pas Recognition paradigm. Patients' satisfaction of HRQoL was related to their performance on the Wisconsin Card Sorting Test. Caregivers' satisfaction was significantly predicted by patients' score on the Faux-pas paradigm. CONCLUSIONS: ToM is impaired in individuals with sTBI and adequate levels of SA. Moreover, their ToM performance predicted HRQoL in the caregivers. From a clinical perspective, these results provide understanding of the potential impact of ToM impairment in subjects with sTBI and their social system.

Health-related quality of life after traumatic brain injury: Italian validation of the QOLIBRI.

The QOLIBRI (Quality of Life after Brain Injury) is a new international health-related quality of life (HRQoL) instrument developed for assessing the consequences of traumatic brain injury (TBI). We report the results of the Italian validation of the QOLIBRI. A total of 147 participants with TBI who had previously been discharged from the Santa Lucia Foundation rehabilitation hospital were recruited to investigate the concurrent validity of the Italian version of the QOLIBRI and to compare this instrument with several functional and cognitive-behavioral scales, taking into account various clinical parameters. The QOLIBRI met the standard criteria for internal consistency, homogeneity and test-retest reliability. The results suggest that it is very sensitive in relation to outcome as measured by the Extended Glasgow Outcome Scale (GOS-E) and other instruments for functional assessment of disability, emotions and subjective health status, including the Hospital Anxiety and Depression Scale and the Short-Form 36. The QOLIBRI avoids some of the limitations of traditional scales for quantifying residual functional capaci-Health-related quality of life after traumatic brain injury: Italian validation of the QOLIBRI, such as the Glasgow Outcome Scale and the GOS-E, and may contribute to the achievement of better quality-controlled care, medical decision-making, rehabilitation planning, and measurement of well-being and HRQoL from the patient's perspective. However, a longitudinal study is needed to assess the responsiveness of the QOLIBRI to changes over time.

Memory and anatomical change in severe non missile traumatic brain injury: ∼1 vs. ∼8 years follow-up.

In previous studies, we investigated a group of subjects who had suffered from a severe non missile traumatic brain injury (nmTBI) without macroscopic focal lesions and we found brain atrophy involving the hippocampus, fornix, corpus callosum, optic chiasm, and optic radiations. Memory test scores correlated mainly with fornix volumes [37,38]. In the present study, we re-examined 11 of these nmTBI subjects approximately 8 yr later. High-spatial resolution T1 weighted magnetic resonance images of the brain (1mm(3)) and standardised memory tests were performed once more in order to compare brain morphology and memory performance originally assessed 3-13 months after head injury (first study) and after 8-10 yr (present study). An overall improvement of memory test performance was demonstrated in the latest assessment, indicating that cognitive recovery in severe nmTBI subjects had not been completed within 3-13 months post-injury. It is notable that the volumes of the fornix and the hippocampus were reduced significantly from normal controls, but these volumes do not differ appreciatively between nmTBI subjects at first (after ∼1 yr) and at second (after ∼8 yr) scans. On the contrary, a clear reduction in the volume of the corpus callosus can be observed after ∼1 yr and a further significant reduction is evident after ∼8 yr, indicating that the neural degeneration in severe nmTBI continues long after the head trauma and relates to specific structures and not to the overall brain.

Urologic dysfunction and neurologic outcome in coma survivors after severe traumatic brain injury in the postacute and chronic phase.

OBJECTIVES: To investigate voiding dysfunction and upper urinary tract status in survivors of coma resulting from traumatic brain injury (TBI), and to compare clinical and urodynamic results with neurologic and psychological features as well as functional outcomes. DESIGN: Observational study focused on urologic dysfunction and neurologic outcome in coma survivors after traumatic brain injury in the postacute and chronic phase. SETTING: A postcoma unit in a rehabilitation hospital. PARTICIPANTS: Consecutive patients (N=57) who recovered from coma of traumatic etiology and who were admitted during a 1-year period to a postcoma unit of a rehabilitation hospital. INTERVENTIONS: Patients underwent clinical urologic assessment, urodynamics with the assessment of the Schafer nomogram and the projected isovolumetric detrusor pressure to evaluate detrusor contractility, ultrasound assessment of the lower and upper urinary tract and voiding cystourethrography, routinely performed, according to the International Continence Society Standards. Neurologic variables assessed were brain injury and disability severity, and neuropsychological status. Neuroimaging identified the site of cerebral lesions. MAIN OUTCOME MEASURES: Urinary symptoms, disability by means of the Glasgow Outcome Scale (GOS), and neuropsychological status by means of the Neurobehavioral Rating Scale (NBRS), and the relationships among them. RESULTS: Of the 57 patients studied, 30 had overactive bladder (urge incontinence) symptoms, 28 had detrusor overactivity, and 18 had detrusor underactivity with associated pseudodyssynergia in 15 of these patients. Eleven patients had hypertrophic bladder; 3, bilateral pyelectasia; and 2, vesicoureteral reflux. Disability measured by GOS was severe in 8 patients and moderate in 27, while recovery was good in 22 patients. The mean NBRS total score indicated a mild cognitive impairment. Neuroimaging showed diffuse brain injury in all patients. Statistically significant relationships were found between urge incontinence, detrusor overactivity, and poor neurologic functional outcome, between detrusor overactivity and right hemisphere damage (P=.0001), and between impaired detrusor contractility and left hemisphere injuries (P=.0001). CONCLUSIONS: Most patients who recovered from coma resulting from TBI have symptoms of overactive bladder syndrome and voiding difficulties. These urinary problems correlate with cerebral involvement and neurologic functional outcome.

Metacognitive unawareness correlates with executive function impairment after severe traumatic brain injury.

UNLABELLED: The aim of this study was to evaluate clinical, neuropsychological, and functional differences between severe traumatic brain injury (TBI) outpatients with good and/or heightened metacognitive self-awareness (SA) and those with impaired metacognitive SA, assessed by the Patient Competency Rating Scale (PCRS). Fifty-two outpatients were recruited from a neurorehabilitation hospital based on the following inclusion criteria: 1) age > or = 15 years; 2) diagnosis of severe TBI; 3) availability of neuroimaging data; 4) post-traumatic amnesia resolution; 5) provision of informed consent. MEASURES: A neuropsychological battery was used to evaluate attention, memory and executive functions. SA was assessed by the PCRS, which was administered to patients and close family members. Patients were divided into two groups representing those with and without SA. Patients with poor SA had more problems than those with good SA in some components of the executive system, as indicated by the high percentage of perseverative errors and responses they made on the Wisconsin Card Sorting Test. Moreover, a decrease in metacognitive SA correlated significantly with time to follow commands (TFC). This study suggests the importance of integrating an overall assessment of cognitive functions with a specific evaluation of SA to treat self-awareness and executive functions together during the rehabilitation process.

Executive function and metacognitive self-awareness after severe traumatic brain injury.

The objective of this study is to identify the clinical, neuropsychological, neuropsychiatric, and functional variables that correlate with metacognitive self-awareness (SA) in severe traumatic brain injury (TBI) outpatients and to assess the influence of the same variables on the sensory-motor, cognitive, and behavioral-affective indicators of SA. This cross-sectional observational study evaluated 37 outpatients from May 2006 to June 2007 in a neurorehabilitation hospital on the basis of the following inclusion criteria: (1) age 8); (3) posttraumatic amnesia (PTA) resolution; (4) capacity to undergo formal psychometric evaluation despite cognitive and sensory-motor deficits; (5) absence of aphasia; (6) availability of informed consent. A neuropsychological battery was used to evaluate attention, memory, and executive functions. SA was assessed by the awareness questionnaire (AQ), administered to both patients and relatives. Decreased metacognitive self-awareness is significantly correlated with increased problems in some components of executive system, even when the AQ subscales were considered separately. The significant correlation found between some components of executive system and metacognitive self-awareness confirmed the importance of addressing this issue to treat SA contextually in the rehabilitation of executive functions.
