In traumatic brain injury (TBI) and stroke rehabilitation, the question of reintegration of the driver into traffic is faced very often. Driving is an important domain and for some patients, return to driving represents a crucial event for community inclusion. The aim of our study was to examine the utility of Glasgow Coma Scale within the first 24 h of injury and the Functional Independence Measure (FIM) at rehabilitation admission for predicting the return to driving. We included 72 patients after TBI or stroke...

Cerebral ischemia affects millions of people worldwide and survivors suffer from long-term functional and cognitive deficits. While stroke and cardiac arrest are typically considered when discussing ischemic brain injuries, there is much evidence that smaller ischemic insults underlie neurodegenerative diseases, including Alzheimer's disease. The "regenerative" capacity of the brain relies on several aspects of plasticity that are crucial for normal functioning; less affected brain areas may take over function previously performed by irreversibly damaged tissue...

In response to injury, the brain produces different neuroprotective molecules, such as insulin-like growth factor I (IGF-I). However, IGF-I is also taken up by the brain from the circulation in response to physiological stimuli. Herein, we analyzed in mice the relative contribution of circulating and locally produced IGF-I to increased brain IGF-I levels after insult. Traumatic brain injury (TBI) induced by a controlled impact resulted in increased IGF-I levels in the vicinity of the lesion, but mice with low serum IGF-I showed significantly lower increases...

Intrauterine growth restriction (IUGR) is a major cause of antenatal brain injury. We aimed to characterize cerebellar deficits following IUGR and to investigate the potential underlying cellular and molecular mechanisms. At embryonic day 18, pregnant rats underwent either sham surgery (controls; n = 23) or bilateral uterine vessel ligation to restrict blood flow to fetuses (IUGR; n = 20). Offspring were collected at postnatal day 2 (P2), P7, and P35. Body weights were reduced at P2, P7, and P35 in IUGR offspring (p < 0...

BACKGROUND: Various reports have suggested that epidemiological patterns of Traumatic Brain Injury (TBI) are changing in high-income countries, but the evidence to support this is often indirect and only a few longitudinal studies exist. We aimed to explore epidemiological patterns of TBI in Belgium over a 10-year period. METHODS: A retrospective analysis of Minimum Hospital Data provided by Statistics Belgium was performed for the period 2003-2012. ICD-9 classification was used to identify TBI and to differentiate subtypes...

Perinatal hypoxic-ischemic brain injury is a major health problem. Adjuvant treatments that improve the neuroprotective effect of the current treatment, therapeutic hypothermia, are urgently needed. The growing knowledge about the complex pathophysiology of hypoxia-ischemia (HI) has led to the discovery of several important targets for neuroprotection. Early interventions should focus on the preservation of energy metabolism, the reduction of glutamate excitotoxicity and oxidative stress, the maintenance of calcium homeostasis, and the prevention of apoptosis...

Epilepsy is a chronic neurological disorder that is increasingly prevalent in developing countries. It is critical to provide appropriate support to patients during seizures in order to prevent injuries. False beliefs regarding the etiology or pathogenesis of the epilepsy and inadequate health information may put patients with epilepsy or other seizure disorders at increased risk of injury. Our objective was to assess the level of epilepsy awareness amongst the general population in Grenada and educate the participants regarding proper first-aid measures...

OBJECTIVES: Vasopressors are not recommended by current trauma guidelines, but recent reports indicate that they are commonly used. We aimed to describe the early hemodynamic management of trauma patients outside densely populated urban centers. METHODS: We conducted a single-center retrospective cohort study in a Canadian regional trauma center. All adult patients treated for traumatic injury in 2013 who died within 24 hours of admission or were transferred to the intensive care unit were included...

Cocaine induces vasoconstriction in cerebral vessels, which with repeated use can result in transient ischemic attacks and cerebral strokes. However, the neuroadaptations that follow cocaine's vasoconstricting effects are not well understood. Here, we investigated the effects of chronic cocaine exposure (2 and 4 weeks) on markers of vascular function and morphology in the rat brain. For this purpose we measured nitric oxide (NO) concentration in plasma, brain neuronal nitric oxide synthase (nNOS or NOS1), HIF-1α, and VEGF expression in different brain regions, i...

In the study of adult stem cells and regenerative mechanisms, planarian flatworms are a staple in vivo model system. This is due in large part to their abundant pluripotent stem cell population and ability to regenerate all cell and tissue types after injuries that would be catastrophic for most animals. Recently, planarians have gained popularity as a model for eye regeneration. Their ability to regenerate the entire eye (comprised of two tissue types: pigment cells and photoreceptors) allows for the dissection of the mechanisms regulating visual system regeneration...

Cardiac arrest affects >550,000 people annually in the USA while 80-90% of survivors suffer from a comatose state. Arousal from coma is critical for recovery but mechanisms of arousal are undefined. Orexin-A, a hypothalamic excitatory neuropeptide, has been linked to arousal deficits in various brain injuries. We investigated the orexinergic system's role in recovery from cardiac arrest-related neurological impairments, including arousal deficits. Using an asphyxial cardiac arrest and resuscitation model in rats, we examine neurological recovery post-resuscitation in conjunction with changes in orexin-A levels in cerebrospinal fluid and orexin-expressing neurons...

OBJECTIVE: Acquired brain injury (ABI) is associated with many physical and psychiatric conditions. Oftentimes, the individual's family members are responsible for providing long-term care, leaving caregivers vulnerable to negative effects of caregiving including stress, depression, and decreased quality of life. Attribution theory suggests that caregivers may blame the individual with the ABI for their injury as a way to understand their own circumstances. The objective of this study was to investigate caregiver coping strategies as possible mediators between caregiver family member blame and caregiver psychosocial outcomes among caregivers of individuals with ABI...

INTRODUCTION: Cerebral ischemia and reperfusion causes physiological and biochemical changes in the neuronal cells that will eventually lead to cell damage. Evidence indicates that exercise reduces the ischemia and reperfusion-induced brain damages in animal models of stroke. In the present study, the effect of exercise preconditioning on brain edema and neurological movement disorders following the cerebral ischemia and reperfusion in rats was investigated. METHODS: Twenty-one adult male wistar rats (weighing 260-300 g) were randomly divided into three groups: sham operated, exercise plus ischemia, and ischemia group (7 rats per group)...

The evolution of adaptive immunity provides enhanced defence against specific pathogens, as well as homeostatic immune surveillance of all tissues. Despite being 'immune privileged', the CNS uses the assistance of the immune system in physiological and pathological states. In this Opinion article, we discuss the influence of adaptive immunity on recovery after CNS injury and on cognitive and social brain function. We further extend a hypothesis that the pro-social effects of interferon-regulated genes were initially exploited by pathogens to increase host-host transmission, and that these genes were later recycled by the host to form part of an immune defence programme...

This article provides a detailed outline of the recovery of a young male patient during his emergence from a vegetative state (VS) 19 months after suffering a severe traumatic brain injury. Several similar cases have been documented, but these tend not to consider the subjective experience of the patient or family; our aim was therefore to provide a detailed account that emphasises our neuropsychological exploration of the impact of the injury on this person, and looks at the experience of his mother along the timeline from his accident to the end of a successful period in rehabilitation...

The neonatal brain is highly susceptible to oxidative stress as developing endogenous antioxidant mechanisms are overwhelmed. In the neonate, superoxide dismutase (SOD) overexpression worsens hypoxic-ischemic injury due to H2O2 accumulation in the brain. Erythropoietin (EPO) is upregulated in 2 phases after HI, early (4 h) and late (7 days), and exogenous EPO has been effective in reducing the injury, possibly through reducing oxidative stress. We hypothesized that exogenous EPO would limit injury from excess H2O2 seen in SOD1-overexpressing mice, and thus enhance recovery after HI...
