After the double-murder suicide, former wrestler Christopher Nowinski contacted Benoit's father, suggesting that years of trauma to his son's brain may have led to his actions. Tests were conducted on Benoit's brain by Julian Bailes, the head of neurosurgery at West Virginia University, and results showed that "Benoit's brain was so severely damaged it resembled the brain of an 85-year-old Alzheimer's patient." He was reported to have had an advanced form of dementia, similar to the brains of four retired NFL players who had suffered multiple concussions, sank into depression, and harmed themselves or others. Bailes and his colleagues concluded that repeated concussions can lead to dementia, which can contribute to severe behavioral problems.

Its traditional bases of support not only took mutually exclusive positions, but found themselves increasingly at odds with each other. Smuts' reluctance to consider South African foreign policy against the mounting tensions of the Cold War also stirred up discontent, while the nationalists promised to purge the state and public service of communist sympathisers.
