LAS VEGAS — Tom Dumont, the 58-year-old guitarist for ska band No Doubt, revealed in a video posted to Instagram that he has been diagnosed with early-onset Parkinson's disease. Dumont filmed the video from his home.

He said he started experiencing symptoms years ago, prompting visits to a doctor and a neurologist. A series of medical tests followed, leading to the early-onset Parkinson's disease diagnosis.

"It's a struggle every day, and I'll make another video with details about what Parkinson's entails. The good news is I can still play music, I can still play guitar. I've been doing really well," he said in the video.

"It helps erase some of the stigma, and it raises awareness obviously, and awareness is really important for prevention and for research," Dumont said.

No Doubt is set to perform at the Sphere venue in Las Vegas from May 6 to June 13.

Bandmates responded publicly to the announcement. No Doubt drummer Adrian Young wrote, "My friend, bandmate, and hero, I love you brother." Bassist Tony Kanal wrote, "Love you beyond words my friend. Can't wait to get on stage with you again."

Dumont joined No Doubt in 1988, two years after the band formed in 1986. The group has gone on hiatus multiple times since its formation and reunited for a performance at the Coachella music festival in 2024 after nearly a decade apart. No Doubt's most recent performance before the Las Vegas residency was at the FireAid LA benefit concert in January 2025.

Parkinson's disease is a neurological disorder that progresses over time and affects movement, according to the Parkinson's Foundation. Symptoms typically include tremors, rigidity, and balance issues that can worsen as the disease progresses.

Other public figures have disclosed Parkinson's diagnoses over the years. Actor Michael J. Fox began experiencing symptoms in 1991 while filming Doc Hollywood and revealed his diagnosis in 1998 in an interview with People magazine while his show Spin City was on the air. Fox has a foundation dedicated to awareness, research, and education about the disease. Boxer Muhammad Ali was diagnosed with Parkinson's in 1982, one year after retiring from boxing. In 2002, Fox testified alongside Ali before Congress to lobby for increased funding for medical research through the National Institutes of Health, and Lonnie Ali spoke on her husband's behalf.
