Without a doubt guitarist Tom Dumont shared a personal update on social media, revealing his Parkinson’s disease diagnosis ahead of the group’s upcoming Las Vegas residency. He spoke candidly about his health, offering insight into his journey while reassuring fans as No Doubt prepares to take the stage at one of entertainment’s biggest hubs.
Tom Dumont suffers from early onset Parkinson’s disease
On April 11, Tom Dumont took to Instagram to share an update on his health. According to the 58-year-old guitarist, he had been experiencing symptoms in recent years, prompting him to see a neurologist and undergo a series of tests to discover the underlying cause of his problems.
“I was diagnosed with early onset Parkinson’s. It’s been a struggle. It’s a struggle every day. And I’ll be doing another video with details on what Parkinson’s entails,” Dumont said.
Parkinson’s disease, according to the Mayo Clinic, is a degenerative neurological disorder whose symptoms can include tremors, stiff muscles, poor balance and speech changes. Although the disease is not cured, patients receive medication or may undergo rehabilitation to reduce symptoms and improve their quality of life. According to statistics, more than 1.1 million Americans are affected by Parkinson’s disease, and approximately 90,000 people are diagnosed each year.
The guitarist shared his story to raise awareness
Dumont reveals his diagnosis because he was inspired by others who have shared their own health journeys with Parkinson’s. “I think it helps erase some of the stigma and it obviously raises awareness. And awareness is really important for prevention and for research,” Dumont said.
Notable people who have been diagnosed with the disease include Michael J. Fox, Muhammad Ali, Neil Diamond and Ozzy Osbourne.
Dumont’s fans and peers reacted to his announcement, praising him for his courage and sharing words of encouragement. His No Doubt bandmate Tony Kanal wrote: “I love you beyond words my friend. I can’t wait to get back on stage with you.”
Despite his diagnosis, Dumont said he was “doing very well.” “The good news is I can still play music. I can still play guitar,” he shared. Elsewhere in the video, he revealed that he was preparing for No Doubt’s Las Vegas residency and had fun revisiting old footage and photos from years past.
“It kind of made me think about how grateful I am for the life that I’ve led as a musician all these years, you know,” the guitarist said, adding his gratitude to the people who have supported him and no doubt over the years. “It’s thanks to our families, our friends, our listeners and you, and everyone who has come to our shows over the years. Thank you,” Dumont said with gratitude.
A true honor to perform at #FireAidLA ❤️

Dumont joined No Doubt as a guitarist in 1988. The ska-punk band released two albums before achieving mainstream success with the release of their third album in 1995, “Tragic Kingdom.” From there, the group had several hit songs, including “Just a Girl”, “Don’t Speak”, “Bathwater”, “It’s My Life” and “Hella Good”.
In 2004, No Doubt went on hiatus, with the members focusing on their personal projects and their families. They reunited several times before taking another hiatus in 2015. In 2024, the group reunited to perform at Coachella, and in January 2025, No Doubt performed for the FireAid LA benefit concert.
No Doubt received nine Grammy nominations and won two awards for Best Pop Performance, first for “Hey Baby” in 2003, followed by “Underneath It All” in 2004.
No Doubt’s upcoming Las Vegas residency
No Doubt’s reunion at the 2025 benefit concert reignited fans’ enthusiasm, eventually leading the band to secure a Las Vegas residency at the Sphere. In December 2025, Gwen Stefani opened up about the reunion, sharing that she and her bandmates had been discussing their comeback for a while. “I think the Sphere is the future, you know what I’m saying? It’s kind of a cross between a concert and a movie,” she said on “The Tonight Show Starring Jimmy Fallon.”
Stefani said their performances were going to be “really nostalgic” for fans and make them feel like they were “going back in time.” “They are a big part of our lives and we want to see them in Vegas,” she exclaimed.
No Doubt’s 18-show residency “Live at Sphere” kicks off May 6.
