Numerous music icons have publicly shared their diagnoses with degenerative diseases, raising public awareness and inspiring many with their courage. These conditions, which progressively worsen over time, often present unique challenges for performers whose careers depend on precise physical and vocal control.
ALS: The Impact on Vocal Legends
Amyotrophic Lateral Sclerosis (ALS), or Lou Gehrig's disease, is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. It is a devastating diagnosis, as it eventually leads to the loss of voluntary muscle control.
One of the most notable singers affected was the Grammy-winning musician Roberta Flack. In November 2022, her representatives announced that she had been diagnosed with ALS, a condition that left her unable to sing and made speaking difficult. Known for timeless hits like 'Killing Me Softly with His Song,' Flack's diagnosis marked a profound shift in her career, forcing her to retire from performing. Despite the physical toll, her representatives noted that her spirit and love for music remained vibrant, and she continued her creative pursuits through her foundation.
Another example is legendary jazz composer Charles Mingus, who was also diagnosed with ALS. While primarily a bassist, the illness severely impacted his ability to perform and compose in his later years, ultimately leading to his death.
Parkinson's Disease in the Music World
Parkinson's disease is a neurodegenerative disorder that primarily affects the dopamine-producing neurons in a specific area of the brain. Symptoms typically progress slowly over time and can include tremors, slowed movement (bradykinesia), and changes in speech.
- Ozzy Osbourne: In January 2020, the Black Sabbath frontman revealed he had been diagnosed with Parkinson's, though he had been managing symptoms for years. While the disease has significantly affected his mobility and balance, his wife, Sharon Osbourne, has stated that it has not affected his voice, although he requires assistance to stand and walk on stage. Osbourne’s story highlights the varying progression and symptoms of the disease. He passed away in July 2025 at the age of 76.
- Morten Harket: The lead singer of the Norwegian synth-pop group a-ha, Morten Harket, revealed his Parkinson's diagnosis in June 2025. The 65-year-old explained that vocal issues were a primary symptom, making it difficult for him to control his voice. The announcement cast uncertainty on his future touring plans, emphasizing how even managed symptoms can pose major obstacles for a performer.
- Linda Ronstadt: Initially diagnosed with Parkinson's in 2013, Linda Ronstadt later discovered she had a related, but distinct, condition called progressive supranuclear palsy. The illness robbed the folk-rock legend of her singing voice, but she has since become a vocal advocate for neurological disease awareness.
Stiff-Person Syndrome and the Fight for Control
Stiff-person syndrome is a rare neurological disorder characterized by muscle rigidity and painful spasms. As an autoimmune condition, its exact cause is unknown, but it severely impacts motor function and can disrupt a singer's ability to control their vocal cords and breathing.
Céline Dion publicly revealed her diagnosis with stiff-person syndrome in December 2022. The disease has caused her severe muscle spasms that make it feel like "somebody is strangling" her when she tries to sing, according to a 2024 interview. Despite the devastating impact, Dion remains determined to perform again and has been undergoing intensive therapy to manage her symptoms. Her story, featured in the documentary 'I Am: Céline Dion,' showcases her fight to regain control and her commitment to her career and fans.
Multiple Sclerosis and Performing Artists
Multiple Sclerosis (MS) is an autoimmune disease that affects the brain and spinal cord, leading to communication problems between the brain and the rest of the body. Symptoms vary widely but can include muscle weakness, numbness, and issues with coordination.
- Walter Williams: The founding member of The O'Jays was diagnosed with MS in 1983. He kept his diagnosis private for nearly 30 years, continuing to perform and tour despite experiencing difficulties with dance moves. His dedication and professional approach enabled him to maintain an active career well into his 70s.
- Clay Walker: Country singer Clay Walker was diagnosed with relapsing-remitting MS in 1996, receiving a grim prognosis at the time. With medical treatment and lifestyle changes, he achieved remission in 1998 and has since become a prominent advocate for MS awareness through his organization, Band Against MS.
Lesser-Known Degenerative Conditions
Some singers face other, less common degenerative conditions that impact their ability to perform.
- Alan Jackson: In September 2021, the country music star announced his diagnosis with Charcot-Marie-Tooth (CMT) disease, a hereditary neurological condition affecting the peripheral nerves. While the disease has impacted his balance and mobility on stage, Jackson has clarified that it does not affect his voice. He has adapted his live performances but continues to record and tour when he can, showcasing his perseverance.
A Comparison of Singers and Their Conditions
| Singer | Degenerative Disease | Primary Impact on Career | Adaptation/Outcome |
|---|---|---|---|
| Roberta Flack | ALS (Amyotrophic Lateral Sclerosis) | Inability to sing and speak easily | Retired from live performance; remained active through foundation |
| Linda Ronstadt | Progressive Supranuclear Palsy (initially suspected Parkinson's) | Loss of singing voice | Retired from singing; became advocate for awareness |
| Ozzy Osbourne | Parkinson's Disease (Parkin 2) | Mobility and balance issues | Adapted live shows (using a throne); continued recording |
| Céline Dion | Stiff-Person Syndrome | Muscle spasms affecting voice and mobility | Focus on recovery and physical therapy; gradual return to performance |
| Alan Jackson | Charcot-Marie-Tooth Disease | Balance and mobility issues on stage | Adapted performances; continued to record and tour |
A Community of Resilience
The stories of these singers serve as powerful examples of human resilience in the face of debilitating health challenges. They have used their platforms to share their vulnerabilities, demystify complex diseases, and raise crucial awareness and funds for research. By being open about their struggles, they have helped others feel less isolated in their own battles with chronic conditions.
Overcoming Adversity
Many of these artists have found new ways to engage with their music and their fans, whether through writing, advocating, or recording. Linda Ronstadt's memoir, for example, shares her journey and coping mechanisms. Similarly, Céline Dion's documentary aims to raise awareness and help others with stiff-person syndrome. Their narratives demonstrate that a diagnosis does not have to be the end of one's creative spirit, but rather a catalyst for a new chapter of purpose.
Conclusion
The question of what singer has a degenerative disease? reveals that many beloved artists have courageously battled severe illnesses behind the scenes. From ALS and Parkinson's to Stiff-Person Syndrome and CMT, their stories shed light on the challenges of living with a progressive condition, especially one that impacts their core professional skills. Their public journeys, marked by resilience, advocacy, and a deep love for their craft, have not only inspired fans but also significantly contributed to wider health awareness and support for others facing similar diagnoses.

The Future of Music and Illness
The conversation started by these public figures encourages a more empathetic and informed understanding of chronic illness. As medical advancements continue, there is hope that future artists with degenerative diseases will have better access to treatments and technologies that allow them to continue sharing their gifts with the world. Their legacies will undoubtedly be defined not only by their music but also by their bravery and honesty in the face of immense adversity.
