Austin Carlile formed Of Mice & Men in 2009 after his departure from Attack Attack!. According to historical records, the band would undergo significant changes throughout their career. Carlile’s journey with the band eventually ended due to health issues and creative differences.
The Health Battle

The band’s European tour reached a turning point in October 2016. They canceled their remaining dates for Carlile to seek medical treatment. His battle with Marfan syndrome, a genetic disorder affecting the body’s connective tissue, had reached a critical point. Carlile acknowledged through social media in late November that his condition wouldn’t “get better.” He revealed he had undergone multiple surgeries. On December 30, 2016, he announced his official departure to focus on his health and relocated to Costa Rica.
Creative Differences

Health issues were the primary public reason for Carlile’s departure. However, another significant factor emerged in February 2017. The creative direction of the band’s follow-up to ‘Restoring Force’ became contentious. Carlile explained in response to a fan’s Instagram comment: “They weren’t going to let me write what I wanted on next record. That’s not gonna happen. I will write what I want despite what that means giving up.” This revealed the artistic tensions that contributed to his exit.
Controversy And Response

Multiple women came forward with allegations of sexual assault against Carlile years after his departure. The claims spanned several years. As reported by Consequence, Carlile responded to these allegations. He stated that the accusations “have been investigated by the appropriate authorities as well as independent journalists and were determined to be unfounded.” He maintained his innocence and extended apologies to various organizations and his former bandmates.
Medical Complications

ABC News reported that Carlile’s performances caused him “violent pain” due to spinal tears from Marfan syndrome. Medical professionals warned that continued performing could cause permanent damage to his spinal cord and nervous system.
His condition worsened in 2018. Loudwire reported that he was hospitalized at Stanford University Hospital due to spinal fluid leaking into his head. This required immediate medical intervention.
Ongoing Treatment

Loudwire later revealed the extent of Carlile’s medical treatment. His treatment regimen included 12 to 24 injections weekly to manage his Marfan syndrome symptoms.
This intensive medical routine demonstrated the severity of his condition. It validated his decision to leave the demanding lifestyle of a touring musician. The situation fundamentally changed both his career path and personal life.
