Michael J. Fox's recent surprise performance with Coldplay at the Glastonbury Festival has highlighted his ongoing battle with Parkinson's disease, diagnosed when he was just 29. Fox, who played guitar during the band's set, shared the emotional experience on Instagram, describing it as 'mind-blowing.' The event has drawn attention to young-onset Parkinson's disease, affecting individuals under 50, as Fox's involvement has been pivotal in raising awareness. Concurrently, new research from University College London reveals that people over 50 who develop anxiety are twice as likely to develop Parkinson's, indicating that anxiety could be an early sign of the disease. This study emphasizes the need for early diagnosis and treatment, potentially improving patient care by linking anxiety to Parkinson's. The findings underscore the increasing prevalence of Parkinson's, which affects over 8.5 million people globally and is the fastest-growing neurological condition.
