Behavioral and affective disorders after brain injury: French guidelines for prevention and community supports

AbstractObjectiveThe purpose of this study was to elaborate practice guidelines for the prevention of behavioral and affective disorders in adult outpatients after traumatic brain injury (TBI); but also to identify the support systems available for family, caregivers of patients with TBI within the community.MethodsThe elaboration of these guidelines followed the procedure validated by the French health authority for good practice recommendations, close to the Prisma statement. This involved a systematic and critical review of the literature looking for studies that investigated the impact of programs in community settings directed to behavioral and affective disorders post-TBI. Recommendations were than elaborated by a group of professionals and family representatives.ResultsOnly six articles were found comprising 4 studies with a control group. Two studies showed a beneficial effect of personalized behavior management program delivered within natural community settings for persons with brain injury and their caregivers. Two other studies showed the relevance of scheduled telephone interventions to improve depressive symptoms and one study emphasized the usefulness of physical training. One study investigated the relevance of an outreach program; this study showed an improvement of the patients’ independence but did not yield any conclusions regarding anxiety and depression.Discussion and recommendationsIn addition to the application of care pathways already established by the SOFMER, prevention of behavioral and affective disorders for brain-injured outpatients should involve pain management, as well as development of therapeutic partnerships. It is recommended to inform patients, their family and caregivers regarding the local organization and facilities involved in the management of traumatic brain injury. The relevance of therapeutic education for implementing coping strategies, educating caregivers on behavioral disorder management, follow-up telephone interventions, and holistic therapy seems established. The level of evidence is low and preliminary studies should be confirmed with larger controlled trials

Repetitive transcranial magnetic stimulation and transcranial direct current stimulation in motor rehabilitation after stroke: An update

AbstractStroke is a leading cause of adult motor disability. The number of stroke survivors is increasing in industrialized countries, and despite available treatments used in rehabilitation, the recovery of motor functions after stroke is often incomplete. Studies in the 1980s showed that non-invasive brain stimulation (mainly repetitive transcranial magnetic stimulation [rTMS] and transcranial direct current stimulation [tDCS]) could modulate cortical excitability and induce plasticity in healthy humans. These findings have opened the way to the therapeutic use of the 2 techniques for stroke. The mechanisms underlying the cortical effect of rTMS and tDCS differ. This paper summarizes data obtained in healthy subjects and gives a general review of the use of rTMS and tDCS in stroke patients with altered motor functions. From 1988 to 2012, approximately 1400 publications were devoted to the study of non-invasive brain stimulation in humans. However, for stroke patients with limb motor deficit, only 141 publications have been devoted to the effects of rTMS and 132 to those of tDCS. The Cochrane review devoted to the effects of rTMS found 19 randomized controlled trials involving 588 patients, and that devoted to tDCS found 18 randomized controlled trials involving 450 patients. Without doubt, rTMS and tDCS contribute to physiological and pathophysiological studies in motor control. However, despite the increasing number of studies devoted to the possible therapeutic use of non-invasive brain stimulation to improve motor recovery after stroke, further studies will be necessary to specify their use in rehabilitation

Predictors and indicators of disability and quality of life 4 years after a severe traumatic brain injury. A Structural Equation Modelling analysis from the PariS-TBI study

ObjectiveTo assess the predictors and indicators of disability and quality of life four years after a severe traumatic brain injury (TBI), using a Structural Equation Modelling (SEM). SEM is a multivariate approach permitting to take into account the complex inter-relationships between individual predictors, in order to disentangle factors which have a direct or indirect relationship with the dependant variable.MethodsThe Paris-TBI study is a longitudinal inception cohort study of 504 patients with severe TBI in the Parisian area [1]. Among 245 survivors, 147 patients were assessed four years post-injury. Two outcome measures were analysed separately using SEM: the Glasgow Outcome Scale-extended (GOS-E) [2], which is a global measure of disability after TBI, and the QOLIBRI, a disease-specific measure of quality of life after TBI [3]. Four groups of variable were entered in the model: demographics; injury severity; psychological and cognitive impairments; somatic impairments.ResultsThe GOS-E was directly significantly related to all four groups of variables (age, gender, severity of injury, psycho-cognitive and somatic impairments). Education duration had an indirect effect, mediated by psycho-cognitive impairments. In contrast, the QOLIBRI was only directly predicted by psycho-cognitive impairments. Age and somatic impairments had an indirect influence on the QOLIBRI, via psycho-cognitive impairments.Discussion/ConclusionDisability and quality of life were directly influenced by different factors. While disability appeared to result from an interaction of a wide range of factors, including demographics, injury severity, psycho-cognitive and somatic deficiencies, quality of life was solely directly related to psycho-cognitive factors. Other factors, such as age and somatic impairments only had an indirect effect

Physical and rehabilitation medicine (PRM) care pathways: Adults with severe traumatic brain injury

AbstractThis document is part of a series of guidelines documents designed by the French Physical and Rehabilitation Medicine Society (SOFMER) and the French Federation of PRM (FEDMER). These reference documents focus on a particular pathology (here patients with severe TBI). They describe for each given pathology patients’ clinical and social needs, PRM care objectives and necessary human and material resources of the pathology-dedicated pathway. ‘Care pathways in PRM’ is therefore a short document designed to enable readers (physician, decision-maker, administrator, lawyer, finance manager) to have a global understanding of available therapeutic care structures, organization and economic needs for patients’ optimal care and follow-up. After a severe traumatic brain injury, patients might be divided into three categories according to impairment's severity, to early outcomes in the intensive care unit and to functional prognosis. Each category is considered in line with six identical parameters used in the International Classification of Functioning, Disability and Health (World Health Organization), focusing thereafter on personal and environmental factors liable to affect the patients’ needs
