McGregor: “When a man is kayoed unconscious, when a man fights me, they need to take 10 months to a year off. You can’t bounce back into a fight. [laughter] And that’s no joke. Everyone laughed there. You can’t take head trauma and bounce back into the gym and spar. These people think you can do that. [Chad] Mendes done it, and now his chin will never recover after the fight. He jumped in too early and went [indecipherable]. You need to take proper time. So I understand that. I bounced José [Aldo]’s head off the canvas like a basketball. [laughter] He needs to take a year to a year and a half off and that’s just for his health. [...] You take head trauma, you sit your ass back in queue and rest, and come back healthy.”
Ten trials involving a total of 185 people were included. Study design and quality, corticosteroid dosages and outcomes varied widely. There was a reduction in oral corticosteroid dose favouring methotrexate in parallel trials ( weighted mean difference - mg per day, 95% confidence interval - to -) and also in cross-over trials ( weighted mean difference - mg per day, 95% confidence interval - to -). There was no difference between methotrexate and placebo for forced expiratory volume in one minute ( weighted mean difference litre, 95% confidence interval - to ). Hepatotoxicity was a common adverse effect with methotrexate compared to placebo ( odds ratio , 95% confidence interval to ).
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.
