#6: Mauro Ranallo
The Medical condition he has struggled with: Bipolar disorder--a condition in which the victim's brain is unable to easily regulate mood. The exact cause remains unknown but is believed to be a combination of brain chemistry and life experience trauma.
Mauro Ranallo is, simply put, the best announcer on any professional wrestling program in any company, period. Not since the days of Lord Alfred Hayes and Gordon Solie has an on-air personality dazzled with his wit, smooth delivery, and emotional resonance with the match and the fans, both in the arena and watching at home.
However, Ranallo has struggled with a serious condition for his entire career, which encompasses both pro wrestling and mixed martial arts; Bipolar depression. This condition actually led to him stepping away from his announce duties for a time. JBL--well known for 'hazing' other WWE employees, though some would call him more of a bully--had apparently been giving Ranallo a hard time from the get go, and things got worse when a jealous Layfield mouthed off to Ranallo about winning a 'best announcer' award from a pro wrestling magazine.
The backlash may have led to JBL's departure from the company, and has certainly led to closer scrutiny of what goes on backstage by WWE management. For example, 'wrestler's court' is now forbidden, as WWE believes it led in part to the bullying culture backstage.
Ranallo then moved to NXT before announcing in 2020 that he is leaving the WWE for a similar role with MMA organization Bellator.
