<P> Omalu is a professor in the UC Davis Department of Medical Pathology and Laboratory Medicine . </P> <P> Omalu's autopsy of former Pittsburgh Steelers player Mike Webster in 2002 led to the re-emergence of awareness of a neurologic condition associated with chronic head trauma called chronic traumatic encephalopathy, or CTE, which had been previously described in boxers and other professional athletes . Webster had died suddenly and unexpectedly following years of struggling with cognitive and intellectual impairment, destitution, mood disorders, depression, drug abuse, and suicide attempts . Although Webster's brain looked normal at autopsy, Omalu conducted independent and self - financed tissue analyses . He suspected that Webster suffered from dementia pugilistica, which is a form of dementia that is induced by repeated blows to the head, a condition found previously in boxers . Using specialized staining, Omalu found large accumulations of tau protein in Webster's brain, which affect mood, emotions, and executive functions similar to the way that clumps of beta - amyloid protein contribute to Alzheimer's disease . </P> <P> Together with colleagues in the Department of Pathology at the University of Pittsburgh, Omalu published his findings in the journal Neurosurgery in 2005 in a paper titled "Chronic Traumatic Encephalopathy in a National Football League Player ." In it, Omalu called for further study of the disease: "We herein report the first documented case of long - term neurodegenerative changes in a retired professional NFL player consistent with chronic traumatic encephalopathy (CTE). This case draws attention to a disease that remains inadequately studied in the cohort of professional football players, with unknown true prevalence rates ." Omalu believed the National Football League (NFL) doctors would be "pleased" to read it and that his research could be used to "fix the problem ." The paper received little attention initially, but members of the NFL's Mild Traumatic Brain Injury (MTBI) Committee later called for its retraction in May 2006 . Their letter requesting the retraction characterized Omalu's description of CTE as "completely wrong" and called the paper "a failure ." </P> <P> Omalu later partnered with Julian Bailes, a neurosurgeon, concussion researcher, and then chairman of the Department of Neurosurgery at West Virginia University School of Medicine, and West Virginia attorney Robert P. Fitzsimmons to found the Brain Injury Research Institute which established a brain and tissue bank . </P>
