Parkinson’s disease is often associated with ageing, but its impact goes far beyond age or profession. With increasing life expectancy and greater awareness, more cases are being diagnosed, yet stigma around the condition, delayed intervention, and limited access to care continue to define the journey.
"Parkinson’s disease is a common neurological condition that gradually affects movement. It usually develops slowly, and early recognition can make a significant difference in quality of life. Early warning signs are subtle and are often overlooked. These may include a slight tremor in one hand at rest, reduced arm swing while walking, soft or low voice, smaller, cramped handwriting, loss of facial expression (masked face) and slowness in routine activities (buttoning a shirt, getting up from a chair). These signs are often mistaken for aging or stress. As the disease progresses, the typical features become more evident, which include resting tremor (often described as pill-rolling), slowness of movement (bradykinesia), muscle stiffness (rigidity) and imbalance or postural instability. Patients may also develop non-motor symptoms such as constipation, sleep disturbances, depression, and a reduced sense of smell, sometimes even before motor symptoms begin," says Dr Sudhir Kumar, Hyderabad-based neurologist.
Several well-known public figures have bravely shared their diagnoses, helping to raise awareness and reduce stigma. From athletes to world leaders and entertainers, these celebrities have shown resilience while living with Parkinson’s disease.

George H. W. Bush
George H.W. Bush was diagnosed with vascular Parkinson's disease, a condition that causes symptoms of parkinsonism due to issues with blood vessels in the brain. As the 41st President of the United States, his health challenges were closely followed by the public and at the time of his death at age 94, Bush was the longest living president in history.
Pope John Paul II
In 2001, Pope John Paul II was diagnosed with Parkinson's disease and his physical decline was visible during his papacy. Despite increasing difficulty with movement and speech, he continued to lead the Catholic Church with full vigour.
Ozzy Osbourne
Heavy metal legend Ozzy Osbourne was diagnosed with PD in 2019. The lead singer of 'Black Sabbath' was open about his health struggles and shed light on the emotional and physical toll of the disease. He passed away in 2025 at the age of 76.
" Although Parkinson’s disease is a chronic condition, it is highly manageable. Modern treatments, including medications, physiotherapy, lifestyle measures, and in some cases advanced therapies like deep brain stimulation, can significantly improve symptoms and maintain independence for many years," explained Dr Kumar.
Parkinson’s disease affects millions globally, but awareness continues to grow, thanks to people who speak openly about their experiences. Understanding their stories can encourage empathy, support, and continued progress toward a better quality of life.
