Chronic Traumatic Encephalopathy

چکیده
42 The Hearing Journal May 2017 C oncussions are something of a clinical conundrum. There has been growing concern that one or more blows to the head can cause lasting brain damage, even after symptoms appear to have resolved. The diagnosis of concussions relies on the evaluation of multiple organ symptoms, but it is important to note that patient reports of their symptoms are inherently subjective. Patients are said to have “recovered” from concussions once those symptoms subside. However, it can be difficult to guarantee that a patient has completely recovered because of the lack of a gold standard biological test for concussions. Neuropathological studies offer compelling evidence that repeated blows to the head cause brain injuries. About a century ago, “punch drunk” boxers were found to have motor, cognitive, and speech problems (JAMA. 1928;91[15]:1103). Post-mortem examination of the boxers’ brains revealed consistent neuropathology evocative of dementia, which aligned with their symptoms (Psychol Med. 1973;3[3]:270).
