  "summary": "This clinic-based observational study assessed mobile phone usage duration in Parkinson's disease patients and examined associations with motor symptoms, cognition, sleep, and other non-motor features. It reports no significant variation in motor severity or cognitive function with phone use, but higher sleep deprivation in the 40–60 year group. The authors conclude that mobile phone usage is significantly associated with earlier onset of parkinsonism, while also reporting an inverse association with disease progression.",
