Body weight variability linked to higher risk of developing Parkinson’s disease

Takeaway

  • Body weight variability, particularly weight loss, is associated with a higher incidence of Parkinson’s disease in a South Korean population.

Why this matters

    This nationwide cohort study in almost 3 million South Korean adults reveals a link between fluctuating body weight and increased risk of Parkinson’s disease. The observation that the risk was greatest in those who lost, rather than gained, weight supports the need for prevention and surveillance of Parkinson's disease in people experiencing weight fluctuations, especially weight loss.
