They regulate the extracellular ionic and chemical environment, and "reactive astrocytes" (along with MICROGLIA) respond to injury.
Recurrent seizures causally related to CRANIOCEREBRAL TRAUMA. Seizure onset may be immediate but is typically delayed for several days after the injury and may not occur for up to two years. The majority of seizures have a focal onset that correlates clinically with the site of brain injury. Cerebral cortex injuries caused by a penetrating foreign object (CRANIOCEREBRAL TRAUMA, PENETRATING) are more likely than closed head injuries (HEAD INJURIES, CLOSED) to be associated with epilepsy. Concussive convulsions are nonepileptic phenomena that occur immediately after head injury and are characterized by tonic and clonic movements.

The terminal deoxynucleotidyl transferase nick end labeling, or TUNEL, assay labels apoptosis on a single-cell level, making it more sensitive than agarose gel electrophoresis for analysis of DNA FRAGMENTATION.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Restoration of blood supply to tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. It is primarily a procedure for treating infarction or other ischemia, by enabling viable ischemic tissue to recover, thus limiting further necrosis. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing REPERFUSION INJURY.

A(2A) adenosine receptor deficiency attenuates brain injury induced by transient focal ischemia in mice. (1/72)

Extracellular adenosine critically modulates ischemic brain injury, at least in part through activation of the A(1) adenosine receptor. However, the role played by the A(2A) receptor has been obscured by intrinsic limitations of A(2A) adenosinergic agents. To overcome these pharmacological limitations, we explored the consequences of deleting the A(2A) adenosine receptor on brain damage after transient focal ischemia. Cerebral morphology, as well as vascular and physiological measures (before, during, and after ischemia) did not differ between A(2A) receptor knock-out and wild-type littermates. The volume of cerebral infarction, as well as the associated neurological deficit induced by transient filament occlusion of the middle cerebral artery, were significantly attenuated in A(2A) receptor knock-out mice. This neuroprotective phenotype of A(2A) receptor-deficient mice was observed in different genetic backgrounds, confirming A(2A) receptor disruption as its cause. Together with complimentary pharmacological studies, these data suggest that A(2A) receptors play a prominent role in the development of ischemic injury within brain and demonstrate the potential for anatomical and functional neuroprotection against stroke by A(2A) receptor antagonists.  (+info)

Reversible neuropsychological deficits after mild traumatic brain injury. (2/72)

OBJECTIVES: To determine the influence of motivation on performance in a divided attention test of patients after mild traumatic brain injury (MBI). METHODS: Comparison of the performance of 12 patients with MBI with 10 patients with severe brain injury (SBI) and 11 healthy controls in a computer supported divided attention task before (T1) and after (T2) verbal motivation. RESULTS: At T1, the MBI group performed the same as the SBI group but significantly worse than the controls in all variables. At T2, the MBI group performed worse than the controls at T2 but the results were equal to the results of the controls at T1 and significantly better than the SBI group at T1 or T2. At T2 the MBI group performed at the level of published norms for the rest. CONCLUSION: Before verbal motivation the MBI group's results in the divided attention task were comparable with those from patients with severe brain injury. They failed to exploit their performance potential when it depended on self motivation but were able to perform at the level of the control group when external motivation was applied.  (+info)

Visual search and visual working memory in patients with chronic focal cortical lesions. (3/72)

Visually guided behavior is known to involve temporo-parietal, inferotemporal, and prefrontal cortex and each of these areas appears to contribute to visual working memory. We explored the extent to which chronic lesions in one of these cortical areas affect visually guided oculomotor performance. We also explore whether possible impairments become more pronounced with increasing memory load. With this aim we recorded saccadic eye movements in 19 patients with a chronic focal postsurgical lesion in either temporo-parietal, inferior temporal or prefrontal cortex. Their results are compared to those of 19 age-matched volunteers. The subjects performed three different visual search tasks with increasing memory load: Instructed search, cue-guided search and memory-guided search. In addition, the latter task was performed with a short (1 s) and a long (6 s) delay. All tasks required the subjects to make a saccade to a single target presented together with one or three distractors. The results indicate that patients with inferotemporal lesions make the most task-related errors. Saccadic reaction times (SRTs) were significantly prolonged in patients with temporo-parietal and prefrontal lesions, but were unaffected in the patients with lesions in the inferotemporal cortex. The spatial accuracy of saccades was lowest in patients with temporo-parietal lesions. An increase in memory load led to more errors, to longer reaction times and to lower saccadic precision. However, the effect was similar across the three patient groups and the controls. An error analysis indicated that both patients and controls tended to weight global (luminance contrast and form) features higher than local features (line-segment orientation) when making difficult perceptual decisions.  (+info)

The structural basis of moderate disability after traumatic brain damage. (4/72)

The objective was to discover the nature of brain damage in survivors of head injury who are left with moderate disability. Macroscopic and microscopic examination was carried out on the brains of 20 persons who had died long after a head injury that had been treated in a neurosurgical unit. All had become independent but had various disabilities (moderate disability on the Glasgow outcome scale) Most deaths had been sudden, which had led to their referral from forensic pathologists. Post-traumatic epilepsy was a feature in 75%. An intracranial haematoma had been evacuated in 75%, and in 11 of the 15 with epilepsy. Diffuse axonal injury was found in six patients, five of the mildest type (grade 1) and one of grade 2. No patient had diffuse thalamic damage but one had a small focal ischaemic lesion in the thalamus. No patient had severe ischaemic brain damage, but three had moderate lesions which were bilateral in only one. No patient had severe cortical contusions. In conclusion, the dominant lesion was focal damage from an evacuated intracranial haematoma. Severe diffuse damage was not found, with diffuse axonal injury only mild and thalamic damage in only one patient.  (+info)

Effectiveness of bed rest after mild traumatic brain injury: a randomised trial of no versus six days of bed rest. (5/72)

BACKGROUND: Outcome after mild traumatic brain injury (MTBI) is determined largely by the appearance of post-traumatic complaints (PTC). The prevalence of PTC after six months is estimated to be between 20 and 80%. Bed rest has been advocated to prevent PTC but its effectiveness has never been established. OBJECTIVE: To evaluate the effect of bed rest on the severity of PTC after MTBI. METHODS: Patients presenting with MTBI to the emergency room were randomly assigned to two intervention strategies. One group was advised not to take bed rest (NO) and the other to take full bed rest (FULL) for six days after the trauma. The primary outcome measures were severity of PTC on a visual analogue scale and physical and mental health on the medical outcomes study 36 item short form health survey (SF-36) at two weeks and three and six months after the trauma. RESULTS: Between October 1996 and July 1999, 107 (54 NO, 53 FULL) patients were enrolled. Outcome variables in both groups clearly improved between two weeks and six months. After adjustment for differences in baseline variables, most PTC tended to be somewhat more severe in the FULL group six months after the trauma, but no significant differences were found. Neither were there any significant differences in the outcome parameters between the two groups after three months. Two weeks after the trauma, most PTC in the FULL group were slightly less severe than those in the NO group, and physical subscores of the SF-36 in the FULL group were slightly better. These differences were not significant. Patients in the FULL group reported significantly less dizziness during the intervention period. CONCLUSIONS: As a means of speeding up recovery of patients with PTC after MTBI, bed rest is no more effective than no bed rest at all. Bed rest probably has some palliative effect within the first two weeks after the trauma.  (+info)

Increased diffusion in the brain of professional boxers: a preclinical sign of traumatic brain injury? (6/72)

BACKGROUND AND PURPOSE: Professional boxing is associated with chronic, repetitive head blows that may cause brain injuries. Diffusion-weighted imaging is sensitive to microscopic changes and may be a useful tool to quantify the microstructural integrity of the brain. In this study, we sought to quantify microscopic alterations associated with chronic traumatic brain injury in professional boxers. METHODS: MR and diffusion-weighted imaging were performed in 24 boxers and in 14 age- and sex-matched control subjects with no history of head trauma. Using distribution analysis, the average diffusion constant of the entire brain (BD(av)) and diffusion distribution width (sigma) were calculated for each subject; findings in professional boxers were compared with those of control subjects. In the boxer group, correlations between diffusion changes and boxing history and diffusion changes and MR imaging findings were assessed. RESULTS: The measured diffusion values in the boxer group were significantly higher than those measured in the control group (BD(av), P <.0001; sigma, P <.01). In the boxer group, a robust correlation was found between increased BD(av) and frequency of hospitalization for boxing injuries (r = 0.654, P <.05). The most common MR finding in the boxer group was volume loss inappropriate to age followed by cavum septum pellucidum, subcortical white matter disease, and periventricular white matter disease. CONCLUSION: Boxers had higher diffusion constants than those in control subjects. Our data suggest that microstructural damage of the brain associated with chronic traumatic brain injury may elevate whole-brain diffusion. This global elevation can exist even when routine MR findings are normal.  (+info)

Diffuse axonal injury associated with chronic traumatic brain injury: evidence from T2*-weighted gradient-echo imaging at 3 T. (7/72)

BACKGROUND AND PURPOSE: Diffuse axonal injury is frequently accompanied by tissue tear hemorrhages. We examined whether high field strength T2*-weighted gradient-echo imaging performed during the chronic stage of traumatic brain injury may have advantages in the evaluation of diffuse axonal injury as compared with T1- and T2-weighted MR imaging. METHODS: Prospective MR imaging of 66 patients (age range, 17-57 years) was performed using a 3-T system 3 to 292 months (median, 23.5 months) after traumatic brain injury. T1-, T2-, T2*-hypointense and T2-hyperintense foci of 1- to 15-mm diameter were registered in 10 brain regions by two readers separately. Foci that appeared hypointense both on the T1- and T2- and/or on the T2*-weighted images were defined as traumatic microbleeds. RESULTS: For 46 (69.7%) of the patients, T2*-weighted gradient-echo imaging revealed traumatic microbleeds. Hyperintense foci were observed on the T2-weighted images of only 15 (22.7%) patients. T2*-weighted imaging showed significantly more traumatic microbleeds (P =.000) than did T1- and T2-weighted imaging. Interobserver agreement was strong (kappa = 0.79, tau = 0.749, P =.000). For 14 (21.2%) of the patients, T2*-weighted gradient-echo imaging revealed traumatic microbleeds in the corpus callosum, whereas for only two (3%), hyperintense callosal lesions were seen on the T2-weighted images. Although a significant correlation existed between the total amount and callosal appearance of traumatic microbleeds and Glasgow Coma Scale scores (P =.000), no correlation existed with extended Glasgow Outcome Scale scores. CONCLUSION: T2*-weighted gradient-echo imaging at high field strength is a useful tool for the evaluation of diffuse axonal injury during the chronic stage of traumatic brain injury. Diffuse axonal injury-related brain lesions are mainly hemorrhagic. The relevance of diffuse axonal injury for long-term clinical outcome is uncertain.  (+info)

Diffusion-weighted imaging of acute corticospinal tract injury preceding Wallerian degeneration in the maturing human brain. (8/72)

BACKGROUND AND PURPOSE: Wallerian degeneration, the secondary degeneration of axons from cortical and subcortical injury, is associated with poor neurologic outcome. Since diffusion-weighted (DW) imaging is sensitive to early changes of cytotoxic edema, DW imaging may depict the acute injury to descending white matter tracts that precedes Wallerian degeneration; this injury is not visible on conventional CT or MR images in the maturing human brain. METHODS: Two neuroradiologists retrospectively analyzed clinical MR images in six children (aged 3 days to 5 months) with DW findings consistent with acute injury of the descending white matter tract due to territorial anterior or middle cerebral artery infarction. In five patients, images were obtained as a part of routine clinical evaluation. The remaining patient was a part of a prospective study of brain injury. Imaging findings were correlated with clinical outcomes. RESULTS: In all six patients, DW imaging performed 2-8 days after the onset of ischemia depicted injury to the descending white matter tract ipsilateral to the territorial infarct. Conventional MR images of the ipsilateral descending white matter tracts were abnormal in three patients. In all five patients for which follow-up results were available, the presence of DW changes was correlated with persistent neurologic disability. CONCLUSION: As shown in this retrospective analysis, DW imaging can depict acute injury to the descending white matter tract in neonates and infants, when conventional MR imaging may show normal findings. These DW findings likely precede the development of Wallerian degeneration, and they may portend a poor clinical outcome.  (+info)

Blast exposure is associated with traumatic brain injury (TBI), neuropsychiatric symptoms, and long-term cognitive disability. We examined a case series of postmortem brains from U.S. military veterans exposed to blast and/or concussive injury. We found evidence of chronic traumatic encephalopathy (CTE), a tau protein-linked neurodegenerative disease, that was similar to the CTE neuropathology observed in young amateur American football players and a professional wrestler with histories of concussive injuries. We developed a blast neurotrauma mouse model that recapitulated CTE-linked neuropathology in wild-type C57BL/6 mice 2 weeks after exposure to a single blast. Blast-exposed mice demonstrated phosphorylated tauopathy, myelinated axonopathy, microvasculopathy, chronic neuroinflammation, and neurodegeneration in the absence of macroscopic tissue damage or hemorrhage. Blast exposure induced persistent hippocampal-dependent learning and memory deficits that persisted for at least 1 month and ...

The study is a retrospective review of the authors experience treating chronic brain injury with HBOT, supplemented by cases communicated to the author, who developed untoward effects during or after their HBOT. The object of the study was to affirm or refute the authors general impression that there was an optimal dose of HBOT in chronic brain injury which was lower than the traditional dose applied in chronic non-central nervous system wounding. Furthermore, when this lower dosage range was exceeded and approached the traditional doses for non-CNS wounding oxygen toxicity would result. To address these impressions the study seeks to review the authors medical records and other patient/doctor communications to the author where side effects of HBOT occurred in the treatment of chronic brain injury and abstract signs, symptoms, and the dose of HBOT employed ...

Chronic neurodegeneration following a history of neurotrauma is frequently associated with neuropsychiatric and cognitive symptoms. In order to enhance understanding about the underlying pathophysiology linking neurotrauma to neurodegeneration, a multi-model pre-clinical approach must be established to account for the different injury paradigms and pathophysiologic mechanisms. We investigated the development of tau pathology and behavioral changes using a multi-model and multi-institutional approach, comparing the pre-clinical results to tauopathy patterns seen in post-mortem human samples from athletes diagnosed with chronic traumatic encephalopathy (CTE). We utilized a scaled and validated blast-induced traumatic brain injury model in rats and a modified pneumatic closed-head impact model in mice. Tau hyperphosphorylation was evaluated by western blot and immunohistochemistry. Elevated plus maze and Morris water maze were employed to measure impulsive-like behavior and cognitive deficits
The diagnosis of chronic traumatic encephalopathy (CTE) upon autopsy in a growing number of athletes and soldiers alike has resulted in increased awareness, by both the scientific/medical and lay communities, of the potential for lasting effects of repetitive traumatic brain injury. While we have come to better understand the clinical presentation and underlying pathophysiology of CTE, the diagnosis of CTE remains autopsy-based, which prevents adequate monitoring and tracking of the disease. The lack of established biomarkers or imaging modalities for diagnostic and prognostic purposes also prevents the development and implementation of therapeutic protocols. In this work the clinical history and pathologic findings associated with CTE are reviewed as well as imaging modalities that have demonstrated some promise for future use in the diagnosis and/or tracking of CTE or repetitive brain injury. Biomarkers under investigation are also discussed with particular attention to the timing of release and

Novel strategies for the Chronic Traumatic Encephalopathy Traumatic brain injury (TBI) is a leading cause of mortally and morbidity in modern warfare. TBI is also a major cause of death and disability in the US, in particular in those under age 40, and ~2% of the US population is living with a chronic TBI-related disability. It is well recognized that a significant percentage of patients including active duty service members (ADSM) and veterans, after sustaining mild traumatic injury (mTBI) may complain of a syndrome including poor concentration, memory dysfunction, and altered mood that may persist for years, which may be defined as the chronic traumatic encephalopathy (CTE). In fact, the long-term pathological consequences of CTE have remained underexplored. In particular, whether chronic post traumatic processes exacerbate chronic neuroinflammation and suppressed neurogenesis is not fully understood. Dr. Shi is focus on the molecular and cellular mechanisms, and novel treatment strategies ...
Two pioneering researchers of brain disease among athletes in violent sports recommended Saturday that investigators conduct special autopsy tests on amateur boxer Tamerlan Tsarnaev to determine whether the Boston Marathon bombing suspect could have been affected by boxing-related brain damage. The researchers expressed serious doubt the disease - chronic traumatic encephalopathy, or CTE - could have factored in the wave of violence that led to Tsarnaevs death early Friday in a firefight with police. But they suggested investigators would be remiss if they did not autopsy Tsarnaevs brain for signs of the disease. Both Cantu and Dr. Robert Stern, cofounders co-founders of the Center for the Study of Chronic Traumatic Encephalopathy Encephelopathy at BU, were personally touched by the tragedy. They have friends and relatives who remain hospitalized from injuries they suffered in the Marathon bombings.
One question theyd like to answer is how much brain injury a person can handle before CTE sets in.

Association football (soccer) is the most popular sport in the world, and the growing recognition that playing soccer is associated with CTE has significant public health implications. However, the health benefits of playing sport are also recognised to reduce all cause mortality, particularly from cardiovascular causes. A public health policy limiting or restricting access to contact sports, which is not carefully considered, may therefore cause more harm than good. This retrospective case control study identified former professional footballers and compared mortality outcomes with a cohort of matched controls.. 7,676 registered soccer players were recruited by searching the records of the Scottish football museum and professional soccer clubs for registered professionals. The records (name and date of birth) were then linked with the community health number (a health record number unique to each individual in Scotland) on a probabilistic basis. Former soccer players were matched to other ...

Such use of a diagnostic test designed for deer is possible because CWD is in a family of neurodegenerative ailments called prion diseases, characterized by protein misfolding that triggers a cascade of ultimately fatal brain damage. Protein misfolding in prion diseases is strikingly similar to cellular malfunction that occurs in human neurological conditions including concussion, chronic traumatic encephalopathy, Alzheimers disease and Parkinsons disease, said University Distinguished Professor Edward Hoover, who works in the CSU Infectious Disease Research and Response Network.. In the last five years, theres been an interest in applying this new technology to other neurological diseases, Davin Henderson, a researcher in the Hoover Laboratory, explained. Chronic traumatic encephalopathy, or CTE, is similar to prion disease..

Damaging tangles of the protein tau dot the brains of people with Alzheimers and many other neurodegenerative diseases, including chronic traumatic encephalopathy, which plagues professional boxers and football players. Such tau-based diseases can lead to memory loss, confusion and, in some, aggressive behavior. But there is no easy way to determine whether peoples symptoms are linked to tau tangles in their brains.. Now, however, a team led by scientists at Washington University School of Medicine in St. Louis has found a way to measure tau levels in the blood. The method accurately reflects levels of tau in the brain that are of interest to scientists because they correlate with neurological damage. The study, in mice and a small group of people, could be the first step toward a noninvasive test for tau.. While further evaluation in people is necessary, such a test potentially could be used to quickly screen for tau-based diseases, monitor disease progression and ...
Mild traumatic brain injuries (mTBI) and/or concussions can negatively affect memory, judgment, reflexes, speech, balance, coordination, and sleep patterns, particularly when more than one injury has been sustained. Additionally, repetitive brain trauma increases the risk for depression, posttraumatic stress disorder (PTSD), and suicide and can lead to impulse control problems, aggressiveness, behavior and personality disturbances, and progressive cognitive decline and neurodegenerative diseases such as chronic traumatic encephalopathy and Alzheimers disease. Both active duty service members and athletes involved in physical contact sports are at an increased risk for suffering from mTBI and may be at increased for functional decline, neurodegenerative dementia, and possible death from repetitive mTBI. Diagnosing mTBI is difficult because it does not have a standardized definition, those with mTBI often do not seek treatment for some time following the injury, an mTBI diagnosis is based on the ...
Hyperbaric oxygen therapy (HBOT) is an intermittent inhalation of 100% oxygen in a hyperbaric chamber at a pressure higher than 1 absolute atmosphere (ATA). There is a growing body of evidence that HBOT can enhance ability of brain to changes its structure (neuroplasticity) in order to recover. Exercise program during HBOT can augment the effect. Although, recent randomized controlled trials in patients with chronic brain injury showed promising results, there are no studies demonstrating combine effect HBOT and exercise rehabilitation program on stroke recovery ...
In a prospective community cohort study in Finland (New England Journal of Medicine1998;338:1715-22) 220 children with epilepsy were followed up for 30 years. Forty four died, most of whom (39) had continued to have seizures which, in 33, were remote symptomatic (resulting from chronic brain injury). Of the survivors, 64% had been seizure free for five years or more and almost half (47%) had stopped antiepileptic drug treatment. They were, however, more likely than people without epilepsy to be unemployed, unmarried, and childless, even in the absence of neurological impairment.. Data from the British Births Survey (now called the Child Health and Education Study) of children born in one week in April 1970 (New England Journal of Medicine1998;338:1723-8) have confirmed the benign nature of febrile convulsions. Neither simple nor complex nor repeated febrile convulsions were followed by detectable impairment of school progress, intelligence, or behaviour at the age of 10.. Flucloxacillin ...
brightcove:5114194401001 default]. This article originally appeared on Time.com.. The link between football and traumatic brain injury continues to strengthen. Now, one of the largest studies on the subject to date finds that 110 out of 111 deceased NFL players had chronic traumatic encephalopathy (CTE), a degenerative brain disorder associated with repetitive head trauma.. Several studies have linked CTE to suicidal behavior, dementia and declines in memory, executive function and mood. Professional athletes may be at higher risk for CTE because of their high likelihood for concussions and other traumatic brain injuries; up to 3.8 million sports-related concussions occur in the United States each year. In 2016, a health official with the NFL acknowledged the link between football and CTE for the first time.. In the new study, published in the Journal of the American Medical Association, researchers looked at the brains of 202 deceased people who had played football at various levels, from high ...
Advanced tests done at the National Institutes of Health on the brain of football star Junior Seau, who committed suicide in May, showed he had signs of a degenerative brain disease, the Associated Press reported.. The examination of Seaus brain showed abnormalities consistent with chronic traumatic encephalopathy (CTE), the kind of injury associated with repetitive head injuries, the AP said.. An initial autopsy on Seau performed by the San Diego County medical examiner found no apparent damage to his brain from years of football. But the Seau family, searching for a reason the 43-year-old Seau took his life, asked for a more in-depth examination by the NIH.. PHOTOS: Junior Seau , 1969 - 2012. Seau killed himself May 2 in his beachfront home in Oceanside with a gunshot to the chest. He left no note and his live-in girlfriend, who was at the gym at the time, told investigators he had given no indication that he was contemplating suicide.. The issue of brain injuries among football players has ...
Researchers at the largest U.S. brain bank have found 87 of 91 NFL players whose brains were analyzed post-mortem tested positive for chronic traumatic encephalopathy (CTE). The degenerative disease is caused by repeated blows to the head-a common occupational risk for football players. CTE may lead to a spectrum of neurological and psychiatric symptoms, including memory…. ...
Long-term traumatic brain injury, or chronic traumatic encephalopathy (CTE), was identified by neuropathologist Dr. Bennet Omalu in 2002. The finding resulted from a brain autopsy performed on Mike Webster, a well-known former Steelers football player. According to a recently produced FRONTLINE documentary called
Examinations of NFL players postmortem brains turned up chronic traumatic encephalopathy in 99 percent of samples in large dataset.
Studies in vivo and in vitro have suggested that the mechanism underlying Alzheimers disease (AD) neuropathogenesis is initiated by an interaction between the cellular prion protein (PrPC) and amyloid-β oligomers (Aβo). This PrPC-Aβo complex activates Fyn kinase which, in turn, hyperphosphorylates tau (P-Tau) resulting in synaptic dysfunction, neuronal loss and cognitive deficits. AD transgenic mice lacking PrPC accumulate Aβ, but show normal survival and no loss of spatial learning and memory suggesting that PrPC functions downstream of Aβo production but upstream of intracellular toxicity within neurons. Since AD and traumatic brain injury (TBI)-linked chronic traumatic encephalopathy are tauopathies, we examined whether similar mechanistic pathways are responsible for both AD and TBI pathophysiologies. Using transgenic mice expressing different levels of PrPC, our studies investigated the influence and necessity of PrPC on biomarker (total-tau [T-Tau], P-Tau, GFAP) levels in brain and blood as

A new JAMA study reveals chronic traumatic encephalopathy was present in a high number of brains of former football players. Researchers looked at the brains of former high school, college and NFL football players. Of the 202 brains analyzed, 177 showed signs of CTE. 110 of the 111 former NFL players brains were diagnosed with CTE. Researchers say that, while the findings are significant, the findings could have limitations due to the players families being motivated to donate the brains as a result of public awareness of the lasting effects of head injuries in football players....

An article published May 16, 2012 in the New York Times discusses similarities between combat veterans who are exposed to roadside bombs and a degenerative brain disease found in athletes. Essentially, football players who are tackled and punched have brain injuries similar to veterans who have lived through explosions.. This research was done at a Veterans Affairs center in Bedford, Massachusetts. The scientists call the damage to the brain by explosions chronic traumatic encephalopathy, or CTE. They replicated explosions on mice and found that within two weeks of the explosion, the CTE was evident. This research caused scientists to believe that many combat veterans have undiagnosed brain trauma and are in jeopardy of having neurological disease. Currently, the only way to determine if someone has CTE is through an autopsy, which is of course too late. This study will hopefully lead to the development of diagnostic testing and drug therapies for this disease.. These new findings cause many to ...

Chronic traumatic encephalopathy (CTE) has garnered greater public attention in recent years after it was diagnosed in several deceased football players, including former New England Patriot Aaron Hernandez and Hall of Famer Junior Seau. CTE is linked to repetitive blows to the head and is thought to lead to mood, behavior and cognitive changes. It can afflict hockey players, combat veterans and others in addition to football players, and currently can be diagnosed only after death through microscopic examination of brain tissue. Some experts caution that media coverage has gotten ahead of the science, which is in the early stages of trying to answer such critical questions as how common CTE is and who is most at risk. Several state legislators want to ban tackle football for younger children, and many parents are questioning whether they should let their children play contact sports. Participation in tackle football among 6- to 12-year-olds is falling. The NFL, meanwhile, has faced increased ...
The pre- teens less than age 12 playing American football leads to symptoms of cognitive, behavioral and mood disorders.. The Researchers study at the Boston University School of Medicine talks on the schools website examined brain injuries for pre-teens playing American football, which includes chronic traumatic encephalopathy (CTE). 246 American football players deceased. out of which, 211 were diagnosed with CTE after death.. When they start to play football in early age, the earlier the symptoms began, says Michael Alosco, an assistant professor of neurology, Boston University School of Medicine and lead author on the study. This is published on Monday in the Annals of Neurology.. Pre-teens starting to play American football at 12 or even earlier than 12 mostly shows the signs of brain injury issues for 13 years on an average before those who start playing the sport after age 12.. The study also supports the fact that each year pre- teens less than 13 began playing American football is ...
Purpose: A role for the tau protein in the pathogenesis of chronic traumatic encephalopathy and the consequences of repeated mild traumatic brain injury (r-mTBI) has received recent attention because of the evidence from high profile autopsy cases and the increased amount of significant health consequences of repetitive mTBI. However data from animal models are limited, and there are no data focusing on effects of tau on the visual system after TBI. Thus, the current study was designed to evaluate the long-term effects of r-mTBI on the visual system of mice expressing human tau protein.. Methods: Male mice expressing human tau protein on a null murine tau background (hTau, Jackson Laboratory, aged 3 months) were used. Single mTBI (s-mTBI; n= 4) was induced according to an established model. According to the same model, repetitive mild traumatic brain injury (r-mTBI; n =4) was induced by applying 5 impacts with an interinjury interval of 48 hours, while repetitive sham (r-sham; n = 3) received ...
Chronic traumatic encephalopathy (CTE) may be more prevalent among football players than feared, according to a new study published in JAMA.. Researchers examined the brains of 202 deceased football players who donated their brains for research. Overall, CTE was diagnosed in 177 players - or 87 percent of those studied. That percentage increased significantly, however, among National Football League players: 110 of the 111 NFL players had CTE, or 99 percent of the donated brains studied.. CTE is a progressive neurodegenerative syndrome associated with repetitive head trauma. It was discovered in 2002 by forensic pathologist Bennet Omalu, MD. While working in the county coroners office in Pittsburgh, Omalu performed an autopsy of Iron Mike Webster, the legendary Pittsburgh Steelers lineman who died at age 50. A Hall-of-Famer, Webster was known for his durability, never missing a game during a stretch between 1975 and 1986. He spent the last decades of his life struggling with dementia, ...

The word concussion evokes a fear these days more so than it ever has, and I know this personally. I played 10 years of football, was struck in the head thousands of times, and I have to tell you, though, what was much worse than that was a pair of bike accidents I had where I suffered concussions, and Im still dealing with the effects of the most recent one today as I stand in front of you.. There is a fear around concussion that does have some evidence behind it. There is information that a repeated history of concussion can lead to early dementia, such as Alzheimers, and chronic traumatic encephalopathy. That was the subject of the Will Smith movie Concussion. And so, everybody is caught up in football and what they see in the military, but you may not know that bike riding is the leading cause of concussion for kids, sports-related concussion, that is. And so another thing that I should tell you that you may not know is that the helmets that are worn in bicycling and football and many ...
All people carry the APOE gene, which has many variations. A 2010 study found that athletes carrying three of the genes four minor variations were 10 times aslikely as those who did not to have reported a concussion and more than eight times as likely to have suffered brain injury as a result. - - - Scientists have known about the dangers of getting hit on the head since the 1920s, when they diagnosed a form of dementia in boxers. They called it dementia pugilistica or punch-drunk syndrome. In recent years, the same condition has become known as chronic traumatic encephalopathy, or CTE. Last year, McAllister and his colleagues completed a study comparing college football players with a group of track and field athletes from the same university. They tested both groups for cognition and memory, and they performed sophisticated imaging that measured changes in their brain cells from the beginning of the season to the end. While the two groups scored equally on the tests, they found that about ...

Football is one of Americas favorite pastimes. In recent years the health risks associated with football have stepped into the national spotlight. The NFL continues to be slammed with head injury lawsuits from well-known players like Tony Doresett, and Jim McMahon. Even with the negative publicity, the NFL has not made serious strides to prevent brain injuries and the traumatic impact they have on players lives.. Because an NFL players careers put them at risk for injury, it falls under the guise of workers compensation. Players from the 1970s through the 1990s, were instructed by NFL staff to use their helmets as a method of blocking opponents, putting their heads and necks directly in harms way. Tracy Scroggins, former Detroit Lions Defensive End, filed a lawsuit citing this, and alleging that the league knew the risks associated with the game and its teachings, specifically with head injuries.. One of the debilitating side effects of head injuries is Chronic Traumatic Encephalopathy ...
WEDNESDAY, May 8, 2019 (HealthDay News) -- High levels of a protein linked with the brain disease chronic traumatic encephalopathy (CTE) were found in the cerebrospinal fluid of ex-athletes who suffered multiple concussions, Canadian researchers say.. The protein tau has been tied to CTE, a rare, degenerative brain disease believed to stem from repeated impacts to the head. People with CTE develop symptoms such as dementia, personality disorders or behavior problems.. This study included 22 former professional athletes, average age 56, with a history of multiple concussions. The men included 12 Canadian Football League players, nine hockey players and one snowboarder. They were compared to 12 people with Alzheimers disease and five healthy people.. Researchers checked tau levels in the participants cerebrospinal fluid, which surrounds the spine and brain.. Of the former athletes, 12 (54%) had high levels of tau. Their levels (averaging 349 picograms per milliliter) were higher than the healthy ...
It could be weeks before the results of toxicology tests are known.. Her manager, Anthony Anzaldo, told NBC4 in Los Angeles that her brain has been given to researcher Dr. Bennet Omalu to see whether there were any effects of chronic traumatic encephalopathy (CTE).. We want to donate her brain, Anzaldo told The New York Daily News. We want to know what made Chyna tick.. CTE, which is believed to be caused by repeated blows to the head, can be diagnosed only after death via an examination of brain tissue.. Dozens of football players who died have been diagnosed with CTE -- including Ken Stabler, Frank Gifford and Junior Seau.. The tall, muscle-bound, raven-haired Laurer billed herself as the 9th Wonder of the World because her wrestling predecessor Andre the Giant had already called himself the eighth. She was a member of the wrestling squad D-Generation X, often wrestled against men and at one point was the WWE womens champion.. After leaving WWE in 2001, Laurer was determined to stay ...
Concussion is, perhaps fittingly, a confused film, one that cant decide whether it wants to be a message movie about a hot-topic issue or a somewhat softer look at a man apart, fighting for what he believes in while (swoon) falling in love.. So director Peter Landesman tries to settle for both, with mixed results. Will Smith, acting again for a change (as opposed to just Being a Big Star or taking on vanity projects that his kids can appear in), is good at both things. But hes much better served as the hard-charging agent of change than the out-of-his-element would-be boyfriend, a side plot that stops the movie cold every time it appears, and it appears fairly often.. Too bad. Brain injuries among football players are at the forefront of discussion about the National Football League, with an alarming number of players suffering from chronic traumatic encephalopathy, or CTE, as a result of violent collisions. Memory loss, violent behavior (off the field; its required in games), even suicides ...
A new imaging technique has allowed the detection of protein abnormalities in the concussed brains of living retired football players that are identical to the autopsy findings of chronic traumatic encephalopathy (CTE) in deceased athletes, researchers reported. Positron emission tomography (PET) scanning using a tracer for tau protein known as FDDNP found significantly higher binding values among retired players than in controls in several regions of the brain, including the amygdala and caudate, according to Dr. Gary Small of the University of California Los Angeles and colleagues. Read this story on www.medpagetoday.com. In addition, the tau binding values were highest in the players who had experienced the most concussions during their careers, which suggests a link between the players history of head injury and FDDNP binding, the researchers wrote in the February American Journal of Geriatric Psychiatry. If this research continues in the direction we expect, it would have a big impact ...
Eanna Falvey addressed the challenges of deciding on return to play in concussion and he challenged what many US newspapers are taking as gospel - that repeated concussion leads to chronic traumatic encephalopathy (CTE). BJSMs 4th issue of 2014 addressed this question and Paul McCrory is on BJSM podcasts (LISTEN HERE).. Senior Associate Editor Peter Brukner (@PeterBrukner) reviewed the challenges of managing groin pain in sport. He argues that Copenhagens Per Holmichs entities approach is a useful one. You can see watch Per Holmich talk about history and clinical examination on YouTube (HERE) and read about the entities (HERE).. To close off the educational event, BJSM Editor in Chief Karim Khan reviewed the pathogenesis of tendinopathy arguing that collagen failure and abnormal tendon cells/matrix needs to be respected even if there are some biochemical changes that have loosely been linked to inflammatory pathways. The new BJSM paper Time to revisit inflammation (OPEN ACCESS) is a ...
The National Football League (NFL) will donate $30 million to the Foundation for the National Institutes of Health in support of research on serious medical conditions prominent in athletes and relevant to the general population.. With this contribution, NFL becomes the founding donor to a new Sports and Health Research Program, which will be conducted in collaboration with institutes and centers at the National Institutes of Health (NIH). Specific plans for the research to be undertaken remain to be developed, but potential areas under discussion include concussion; chronic traumatic encephalopathy; the potential relationship between traumatic brain injury and late life neurodegenerative disorders, especially Alzheimer disease; chronic degenerative joint disease; the transition from acute to chronic pain; sudden cardiac arrest in young athletes; and heat and hydration-related illness and injury.. The announcement of the philanthropic gift, the largest that NFL has given in the leagues 92-year ...

After examining the brains of former professional football players, researchers might be a step closer to diagnosing the devastating brain disease chronic traumatic encephalopathy in the living, according to a study published Wednesday in the New England Journal of Medicine.
Dear Mr. Bettman:. Its time to act. The National Hockey League must take immediate steps to ban fighting and outlaw all blows to the head. And you, Mr. Bettman, as league commissioner, must lead the way.. Fighting in hockey can no longer be a long-debated issue pitting those who find it barbaric and unsportsmanlike and those who argue that its an integral part of the fabric of the game. The growing mound of research on sports concussions and brain injuries has taken the fighting issue to an entirely different level. Were talking about short-and-long-term damage to the brain, the very foundation of who we are as people.. Commissioner Bettman, its very possible that concussions and degenerative brain disease caused by blows to the head - such as chronic traumatic encephalopathy (CTE) - will be the biggest issue in sports in the coming decade. Continuing to downplay what we know about sports-based brain injuries, while simultaneously supporting fighting as an elemental aspect of theNHLgame, is ...

CN) - The risk of developing serious brain diseases among athletes of sports other than football could be more significant than previously expected, after new research shows signs of such issues in the brains of six deceased soccer players.. In findings published Tuesday in the journal Acta Neuropathologica, researchers at University College London present the results of post-mortem tests on the players brains - which revealed that four of the six brains examined had chronic traumatic encephalopathy, or CTE. All of the brains had signs of Alzheimers disease.. While the study population is small, the findings highlight the risks posed by repeated blows to the head in sports and athletic leagues other than the National Football League, which has received criticism over what critics consider the leagues insufficient response to evidence of former players developing - and sometimes dying from - severe brain diseases.. The rate of CTE identified in the subjects brains far exceeds the 12 percent ...
Researchers studying the link between football and chronic traumatic encephalopathy found that 99 percent of the brains donated by families of former NFL players showed signs of the neurodegenerative disease, according to a new study published Tuesday.

The application of hyperbaric oxygen therapy (HBOT) to chronic traumatic brain injury (TBI) can be traced to clinical practice and research in South Florida and New Orleans, Louisiana. It is well known that the practice of HBOT in chronic neurological conditions was pioneered by the late Dr. Richard Neubauer in the 1970s. Beginning with a serendipitous finding of gratuitous neurological improvement in two multiple sclerosis patients undergoing HBOT for chronic bone infections, Dr. Neubauer began applying HBOT to patients with other neurological conditions, primarily stroke. In 1994, he published his first case of HBOT treatment of chronic TBI in the Southern Medical Journal.. ...
Boxing is a striking combat sport that is contested in both amateur and professional competitions with the Olympic Games the pinnacle of amateur boxing. Bouts consist of 3 x 3 minute rounds for men and 4 x 2 minute rounds for women with 1-minute rest between rounds. Successive bouts in a tournament are fought over a number of days with one bout per day. The format in professional boxing varies widely and may include up to 10 or more rounds in a bout. Boxing bouts are characterised by high paced, high intensity action requiring both aerobic and anaerobic fitness as well as considerable skill.. A key feature of boxing competition is the grouping of athletes into weight divisions in an attempt to create an even playing field in which one competitor does not have a significant size or strength advantage over another (see table below for amateur boxing weight division details).. To ensure athletes have made weight, official weigh-ins are held prior to competition. Generally weigh-in occurs the ...
Nathan Croucher, a 24 year old construction worker and champion amateur boxer has been banned from professional boxing after a compulsory brain scan showed an abnormality which makes him susceptible to brain injury. About the ban, he said I am very disappointed but Im just focussing on my family and my work now.1 Croucher is the third boxer in the last 12 months found to have a brain abnormality and to be banned from professional fighting.1-4 The other two boxers were already fighting professionally. One is reported to be upset by the ban, while the other understood the potential dangers and did not object to his licence being revoked.5. The State Government introduced compulsory brain scans after the death of boxer Ahmad Popal in April 2001. Popal was the third boxer since 1974 to die from blows sustained in the ring.5 Since June 2001, Victorias professional boxers must undergo a magnetic resonance imaging (MRI) brain scan when they register as professional, every three years when then ...

Although PD and Parkinsonism are sometimes interchanged, theyre not exactly the same and some brain experts explain that its actually Parkinsonism that is linked more to boxing. Parkinsonism is actually the general condition and PD is just a type of it.. Repetitive head trauma. Permanent injury to the brain cells results from repetitive head trauma. The brain cells or neurons in an area of the brain called substantia nigra deteriorate; hence unable to produce a vital brain chemical known as dopamine. Dopamine serves as a chemical messenger responsible for coordinating smooth and balanced muscle movement. When theres dopamine deficiency, one loses the ability to control body movements.. In boxing, the head is hit at a high speed and with great force, causing shear movement between different brain tissues, resulting in small bleeding areas called microhemorrhages. This could not be detected with the old CT scans but with modern brain imaging techniques, theyre able to identify these.. Some ...
For some eye-opening examples of how Americans compile toplists read Heavyweight Boxing Rankings (3) TOP 10 by boxing experts -OR- Grandpas champions. Actually even the last statement (Number of world championships won) is using an outside-of-the-ring-achievement because world championship is merely a NAME / TAG for a fight. It has nothing to do with the fight itself:. When a boxing organization calls a fight world championship its mainly an orientation point for the audience or a PR stunt to raise ticket prices.. Thats the main reason why there are so many world championships, so many weight divisions and so many boxing organizations: Because 300+ world championships (17 weight classes * 20 world boxing governing bodies) generate more money than just 8 world championships.. Other than that world championship has hardly any value. Would you like to watch a fight between Wladimir Klitschko and Lennox Lewis? I guess you would. Would you still like to watch the fight even when I told you ...
This past week, heavyweight world champion Tyson Fury voluntarily vacated multiple titles on the grounds that he was medically unfit to compete due to mental illness. The British Board of Boxing Control has since suspended his boxing license in addition to stripping his World Boxing Organization, World Boxing Association and International Boxing Organization accolades.. There has already been a great deal of controversy surrounding Fury, who was accused of doping and doing cocaine last year. The former charge is currently under investigation by the UK Anti-Doping body.. His yearslong battle with manic depression only came to light this past month in a Rolling Stone interview, in which Fury admitted to using cocaine as a coping mechanism. He cited his increased visibility as the reason he sank so deeply into depression, and discussed the racial hatred he has faced as a Traveller, a term used for an ethnic group of people in the UK and Ireland who have historically faced discrimination Today, ...

Most bodyweight workouts end up making you lose muscle and strength. By ignoring that athletes have been doing simple bodyweight workouts for decades and have gained strength and speed while losing fat, there is a reason why boxing bodyweight workouts are better than ancient bodyweight workouts and i.e. Boxers are fighters. They train for a battle, so they have to get tougher and leaner without losing their agility and muscles. Following are the three major reasons that clarify Why boxing bodyweight workouts are healthier than simple bodyweight workouts:.

What appeals most to me about acting is the ability to step into the shoes of others. Being able to experience different human emotions and walk away (mostly unscathed). I love creating characters. I love being able to surprise people. When I was younger, I always enjoyed a good action movie. But I feel now, as Ive matured, I prefer films with strong performances - the genre doesnt matter.

In time, with the help of trainer Maurice Eudeline (Paolo Seganti), Carnera rose to the top of the fight game and became an international sports star. However, Carneras business savvy didnt match his physical power; he discovered in his later years that See and ...
