Chronic traumatic encephalopathy or CTE is a progressive neurodegenerative disease that affects the brain of individuals who have suffered repetitive brain trauma. CTE is found in some football players and other athletes who have sustained frequent and repetitive head trauma. The term was first used as a diagnosis in 2005.
In 2002, Dr. Bennet Omalu, a neuropathologist, performed an autopsy on Mike Webster, a retired center for the NFL Pittsburgh Steelers who had exhibited progressive dementia in middle age. On examining slides of his brain taken during the autopsy, Dr. Omalu discovered abnormal accumulations of tau proteins, with topographic patterns different from other degenerative brain disease such as Alzheimer disease.
In 2005 Dr. Omalu, coauthored an article about these findings, Chronic Traumatic Encephalopathy in a National Football League Player, in the Journal of Neurosurgery, The term chronic traumatic encephalopathy had previously been used as a descriptive term, but not as a diagnosis.
Chronic traumatic encephalopathy is a good example of how ancient words are used to name a modern disease.
- chronic means disease that lasts a long time and is derived from the Greek word chronos meaning time, and has existed since the time of Hippocrates
- traumatic means occurring as a result of injury and is derived from the term trauma an ancient Greek word that means, then as now, injury
- encephalopathy means disease of the brain. It comprises Greek word parts en meaning in; cephal meaning head; path meaning disease
CTE is now used as a diagnosis by physicians and in medical literature. Currently 87 former football players have tested positive for the disease. Research is ongoing and one area of study is focused on using PET scans to diagnose the disease in the living.
