That didn't stop him." Seau had insomnia for at least the last seven years of his life, and he was taking zolpidem (Ambien), a prescription drug commonly prescribed for sleep disorders. Seau's autopsy report released later in August 2012 by the San Diego County medical examiner indicated that his body contained no illegal drugs or alcohol, but did show traces of zolpidem. No apparent signs of brain damage were found, nor was he determined to have exhibited mood changes and irritability often apparent with concussions and brain damage. There was speculation that Seau suffered brain damage due to CTE, a condition traced to concussion-related brain damage with depression as a symptom, as dozens of deceased former NFL players were found to have CTE. Seau's family donated his brain tissue to the National Institute of Neurological Disorders and Stroke, part of the NIH; other candidates included the Center for the Study of Traumatic Encephalopathy and the Brain Injury Research Institute. Citing the Seau family's right to privacy, NIH did not intend to release the findings. On January 10, 2013, Seau's family released the NIH's findings that his brain showed definitive signs of CTE. Russell Lonser of the NIH coordinated with three independent neuropathologists, giving them unidentified tissue from three brains including Seau's. The three experts along with two government researchers arrived at the same conclusion. The NIH said the findings on Seau were similar to autopsies of people "with exposure to repetitive head injuries." On January 23, 2013, Seau's family sued the NFL over the brain injuries he had over his career. In 2014, his family continued to pursue the lawsuit while opting out of the NFL concussion lawsuit's proposed settlement, which was initially funded with $765 million. The family reached a confidential settlement with the league in 2018. The Seaus' attorney said that they were "pleased" with the resolution. Legacy Seau was known for his passionate playing style, including a fist-pumping dance he performed after big plays. Rick Gosselin of The Dallas Morning News said Seau "probably was the most dynamic player of his era". NFL head coach Norv Turner, who coached Seau as well as faced him as an opponent, said, "The No. 1 thing about Junior was that he was such an explosive player he'd defeat one-on-one blocks and he was a great tackler." Seau's quickness allowed him to freelance, which sometimes put him out of position. "People
