The initial autopsy shows no evidence of brain damage:
Nothing in the autopsy report lists concussions or brain damage as related or contributory to the manner or cause of death. Nor is there anything that suggests the mood changes and irritability often associated with concussions and brain damage. In its description of the central nervous system, Nelson wrote that features of the brain were symmetrical, showed no signs of injury or lesions, and that the arteries at the base of the brain "have no atherosclerotic changes or aneurysms."The autopsy and toxicology results were released after San Diego news agencies requested them as public documents. Officials at the county medical examiner's office, citing respect for the Seau family, declined to discuss the findings.
The "release of materials for study was done at the request of the next of kin," said Sarah Gordon, a spokeswoman for the medical examiner.
