INTRODUCTION: Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to repetitive head injuries. CTE symptoms include changes in mood, behavior, cognition and motor function, however CTE is only currently diagnosed post-mortem. Using a rat model of recurrent traumatic brain injury (TBI) we demonstrate rodent deficits that predict the severity of CTE-like brain pathology. METHODS: Bilateral, closed skull, mild TBI was administered once per week to 35 WT rats, 8 rats received 2 injuries ('2xTBI'), 27 rats received 5 injuries ('5xTBI') and 13 rats were sham controls...

Chronic traumatic encephalopathy (CTE) is a progressive degenerative disorder associated with repetitive traumatic brain injury. One of the primary defining neuropathological lesions in CTE, based on the first consensus conference, is the accumulation of hyperphosphorylated tau in gray matter sulcal depths. Post-mortem CTE studies have also reported myelin loss, axonal injury and white matter degeneration. Currently, the diagnosis of CTE is restricted to post-mortem neuropathological analysis. We hypothesized that high spatial resolution advanced diffusion MRI might be useful for detecting white matter microstructural changes directly adjacent to gray matter tau pathology...

In retired professional association football (soccer) players with a past history of repetitive head impacts, chronic traumatic encephalopathy (CTE) is a potential neurodegenerative cause of dementia and motor impairments. From 1980 to 2010, 14 retired footballers with dementia were followed up regularly until death. Their clinical data, playing career, and concussion history were prospectively collected. Next-of-kin provided consent for six to have post-mortem brain examination. Of the 14 male participants, 13 were professional and 1 was a committed amateur...

BACKGROUND AND PURPOSE: Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease occurring most commonly in athletes and is caused by repeated concussive or subconcussive blows to the head. The main purpose of this review is to evaluate the published literature on chronic traumatic encephalopathy (CTE) in athletes participating in high-impact sports. In particular, we highlight the significance of concussive and subconcussive impacts in multiple sports, elucidate the differences between clinical/pathological features of CTE and related neurodegenerative diseases, and provide an explanation for the variation in clinical presentation between athletes of different sports...

The chronic effects of repetitive head impacts (RHI) on the development of neuroinflammation and its relationship to chronic traumatic encephalopathy (CTE) are unknown. Here we set out to determine the relationship between RHI exposure, neuroinflammation, and the development of hyperphosphorylated tau (ptau) pathology and dementia risk in CTE. We studied a cohort of 66 deceased American football athletes from the Boston University-Veteran's Affairs-Concussion Legacy Foundation Brain Bank as well as 16 non-athlete controls...

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disorder most commonly associated with repetitive traumatic brain injury (TBI) and characterized by the presence of neurofibrillary tangles of tau protein, known as a tauopathy. Currently, the diagnosis of CTE can only be definitively established postmortem. However, a new positron emission tomography (PET) ligand, [(18)F]T807/AV1451, may provide the antemortem detection of tau aggregates, and thus various tauopathies, including CTE. Our goal was to examine [(18)F]T807/AV1451 retention in athletes with neuropsychiatric symptoms associated with a history of multiple concussions...

Diagnostic and prognostic biomarkers for mild traumatic brain injury (TBI), also known as concussion, remain a major unmet clinical need. Moderate to severe TBI can be diagnosed definitively by clinical assessment and standard neuroimaging techniques that detect the gross damage to the brain parenchyma. Diagnostic tools for mild TBI are lacking and, currently, the diagnosis has to be made on clinical grounds alone, because most patients show no gross pathological changes on CT. Most patients with mild TBI recover quickly, but about 15% develop an ill-defined condition called postconcussive syndrome (PCS)...

Chronic traumatic encephalopathy (CTE) is a progressive neurodegenerative disorder associated with repetitive traumatic brain injury. Multiple system atrophy (MSA) is a Parkinsonian disorder that can result in repetitive falls with associated head trauma. We hypothesized that patients with neurodegenerative disorders like MSA could develop CTE pathology. Therefore, we assessed CTE pathology in 139 MSA cases in our brain bank. Sections from convexity cerebral cortices were screened by immunohistochemistry with anti-phospho-tau antibody...

With regard to persistent posttraumatic headache, there is legitimate concern that duration of symptoms may have an impact on the efficacy of future treatment attempts. Without neuropathologic confirmation, a clinical diagnosis of chronic traumatic encephalopathy cannot be made with a high degree of confidence. Sport-related headaches are challenging in a return-to-play context, because it is often unclear whether an athlete has an exacerbation of a primary headache disorder, has new-onset headache unrelated to trauma, or is in the recovery phase after concussion...

IMPORTANCE: Chronic traumatic encephalopathy (CTE) refers to pathologic changes that have been found in some individuals with a history of repetitive traumatic impact to the head (hereinafter referred to as head trauma). These changes cannot be assessed during the clinical evaluation of a living patient. OBSERVATIONS: The neuropathologic features, taxonomy, history, role of biomarkers in diagnosis, and existing criteria of CTE are reviewed. Previous criteria have been proposed to approach the living patient; however, a unified, specific approach is needed for the practicing clinician...

Brain injuries are becoming increasingly common in athletes and represent an important diagnostic challenge. Early detection and management of brain injuries in sports are of utmost importance in preventing chronic neurological and psychiatric decline. These types of injuries incurred during sports are referred to as mild traumatic brain injuries, which represent a heterogeneous spectrum of disease. The most dramatic manifestation of chronic mild traumatic brain injuries is termed chronic traumatic encephalopathy, which is associated with profound neuropsychiatric deficits...

BACKGROUND: Chronic traumatic encephalopathy (CTE) is a tauopathy associated with prior exposure to repetitive head impacts, such as those incurred through American football and other collision sports. Diagnosis is made through neuropathological examination. Many of the clinical features of CTE are common in the general population, with and without a history of head impact exposure, making clinical diagnosis difficult. As is now common in the diagnosis of other neurodegenerative disorders, such as Alzheimer's disease, there is a need for methods to diagnose CTE during life through objective biomarkers...

Traumatic brain injury (TBI) remains a major public health and socio-economic problem, and 70-90% of all TBIs are classified as mild. Mild TBIs and concussions are mostly considered to be non-serious conditions with symptoms subsiding within a few days or weeks. However in 10-15% of patients, the symptoms persist one year after concussion and mostly include headache, fatigue, irritability, and cognitive problems (e.g. memory, concentration). These persisting symptoms negatively influence patient daily activities as postconcussion syndrome (PCS)...

CONTEXT: The diagnosis of chronic traumatic encephalopathy (CTE) can only be made pathologically, and there is no concordance of defined clinical criteria for premorbid diagnosis. The absence of established criteria and the insufficient imaging findings to detect this disease in a living athlete are of growing concern. EVIDENCE ACQUISITION: The article is a review of the current literature on CTE. Databases searched include Medline, PubMed, JAMA evidence, and evidence-based medicine guidelines Cochrane Library, Hospital for Special Surgery, and Cornell Library databases...

In this review we present the most recent advances in nuclear medicine imaging as a diagnostic and management tool for dementia. The clinical diagnosis of dementia syndromes can be challenging for physicians, particularly in the early stages of disease. Given the growing number of individuals affected by dementia, early and accurate diagnosis can lead to improved clinical management of patients. Although tests are available for exclusion of certain causes of cognitive impairment, the results rarely allow the clinician to make a definitive diagnosis...

Chronic traumatic encephalopathy (CTE) is a neurodegeneration characterized by the abnormal accumulation of hyperphosphorylated tau protein within the brain. Like many other neurodegenerative conditions, at present, CTE can only be definitively diagnosed by post-mortem examination of brain tissue. As the first part of a series of consensus panels funded by the NINDS/NIBIB to define the neuropathological criteria for CTE, preliminary neuropathological criteria were used by 7 neuropathologists to blindly evaluate 25 cases of various tauopathies, including CTE, Alzheimer's disease, progressive supranuclear palsy, argyrophilic grain disease, corticobasal degeneration, primary age-related tauopathy, and parkinsonism dementia complex of Guam...

Despite the extensive media coverage associated with the diagnosis of chronic traumatic encephalopathy (CTE), our fundamental understanding of the disease pathophysiology remains in its infancy. Only recently have scientific laboratories and personnel begun to explore CTE pathophysiology through the use of preclinical models of neurotrauma. Some studies have shown the ability to recapitulate some aspects of CTE in rodent models, through the use of various neuropathological, biochemical, and/or behavioral assays...

Aggregated tau protein is a major neuropathological substrate central to the pathophysiology of neurodegenerative diseases such as Alzheimer's disease (AD), frontotemporal dementia, progressive supranuclear palsy, corticobasal degeneration and chronic traumatic encephalopathy. In AD, it has been shown that the density of hyperphosphorylated tau tangles correlates closely with neuronal dysfunction and cell death, unlike β-amyloid. Until now, diagnostic and pathologic information about tau deposition has only been available from invasive techniques such as brain biopsy or autopsy...
