Researchers at Toronto Western Hospital's Canadian Concussion Centre discover chronic traumatic encephalopathy in the brain of a deceased patient without a history of concussions, according to researchers at the Canadian Concussion Center at Toronto Western Hospital, who say it is the first known case of that class.
This discovery was obtained by an autopsy that examined the brain of a said patient, who in his history had seven years of amyotrophic lateral sclerosis. In the investigation, relatives of the patient were consulted, who reported that he had no history of head trauma or participation in activities associated with the risk of a concussion.
Dr. Lili-Naz Hazrati, the neuropathologist who was part of the research team was responsible for performing the autopsy, says that the patient not only had no known head trauma but also showed no signs of dementia or cognitive impairment, in fact, he had a high mental functioning until the day of his death.
Hazrati also mentions that they do not question that there may be a relationship between repetitive brain trauma and brain degeneration, but now there are more questions than answers regarding the causes of CTE, which generates more reasons to continue with the investigations.
According to Dr. Charles Tator, director of the concussion center and co-author of the study, he believes that as researchers, they should continue to where the evidence leads, with the possibility that the CTE could affect a wider range of people. As more information is obtained from such a disease, it can be better understood to the extent that it can be treated and perhaps prevented.
