No Doubt guitarist Tom Dumont reveals Parkinson's diagnosis before Las Vegas residency

No Doubt guitarist Tom Dumont said he has been diagnosed with early onset Parkinson’s disease, a disclosure that comes just before the band’s high-profile Las Vegas residency and puts a human face on the physical stakes of a major touring schedule.

The 58-year-old musician said in a video posted to Instagram on Saturday, April 11, that he had been dealing with symptoms for a number of years before seeing a doctor and neurologist and undergoing a series of tests. Dumont said the diagnosis has been “a struggle” and “a struggle every day,” but added that he can still play guitar and intends to perform with No Doubt.

The band is set to begin its Sphere engagement in May 2026 at Sphere at The Venetian in Las Vegas, a run being described as No Doubt’s first extended series of shows in nearly 14 years. The originally announced dates were May 6, 8, 9, 13, 15 and 16, and Sphere Entertainment Co. later added six more shows on May 21, 23, 24, 27, 29 and 30 after strong fan demand.

Dumont’s announcement arrives as No Doubt revisits one of the most commercially durable catalogs of the 1990s. The group, fronted by Gwen Stefani and joined by Tony Kanal, Adrian Young and Dumont, reunited for Coachella in April 2024 and again for FireAid in January 2025. The Las Vegas residency comes as coverage around the band marks the 30th anniversary of Tragic Kingdom, the 1995 album that turned No Doubt into global stars.

Beyond the band’s return, the diagnosis highlights a disease that affects more than 1.1 million people in the United States, with nearly 90,000 new diagnoses each year. The Parkinson’s Foundation says the illness is often harder to recognize in younger adults, where symptoms may be mistaken for normal aging or other conditions. Medical sources including Johns Hopkins Medicine describe Parkinson’s diagnosed before age 50 as young-onset or early-onset Parkinson’s disease.

For Dumont, the timing underscores both uncertainty and resolve. He has said the condition has been part of his life for years, yet he remains committed to the stage work ahead as No Doubt prepares to return to Las Vegas.
