Chronic Traumatic Encephalopathy

This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease described in boxing, but also in contact sports such as American football. Soccer, due to repeated headers, could also be associated, albeit to a lesser degree, with the development of this type of pathology. Indeed, it has been shown that playing soccer can be accompanied by cognitive impairments, and neurodegenerative brain abnormalities have been described in neuropathology studies of former professional soccer players. Subradiological brain abnormalities have been found in multimodal MRI in various sports. Similarly, a decrease in cognitive performance has been described. The discovery of this type of anomaly in a population of professional footballers nearing the end of their careers could lead to: * The implementation of appropriate monitoring for professional footballers through early detection of lesions via MRI and cognitive disorders * The implementation of preventative measures for professional footballers, but also for amateur footballers from a very young age.

CMK-0301 is a multi-site, randomized clinical trial to evaluate the safety and efficacy of \[F-18\]Flornaptitril-PET (F-18 FNT-PET) for the prediction of clinical progression of Mild Cognitive Impairment (MCI) with either Suspected Chronic Traumatic Encephalopathy (CTE) or Alzheimer's Disease (AD). The primary objectives of the study are to: (1) To determine the accuracy of F-18 FNT-PET in prediction of clinical decline and (2) To assess the safety and tolerability of F-18 FNT. The secondary objectives include: (1) To demonstrate the feasibility of F-18 FNT-PET in differentiation of participants with suspected chronic traumatic encephalopathy (CTE) from those with suspected Alzheimer's disease (AD) by trained image readers, (2) To evaluate disease progression in participants with suspected CTE or AD and (3) To evaluate the correlation between F-18 FNT-PET regional and summary visual reads scan and other assessments.

to examine the relationship between repeated concussions and late decline of brain function. In addition, all participants agreeing to participate in the study will be asked to will their brains to The Krembil Neuroscience Centre Concussion Project at the Toronto Western Hospital with the consent and full knowledge of their families and doctors. However, it is possible to participate in the research without agreeing to a brain donation. The Project Team is specifically attempting a clinical-MRI-brain tissue research analysis to determine the exact mechanism of the damage to brain tissue following repeated concussions. This condition is known as chronic traumatic encephalopathy (CTE), and shows an abnormal protein in the brain called tau-protein.
