Steps Predict Parkinson's: Early Sign or Cause?
8 Dec
Summary
- Lower daily step counts are linked to later Parkinson's disease diagnoses.
- Activity tracker data showed a correlation between steps and Parkinson's risk.
- Low activity may be an early symptom, not a direct cause of Parkinson's.
A large-scale study analyzing activity tracker data from nearly 95,000 adults has revealed a notable link between daily step count and the later diagnosis of Parkinson's disease. The research indicated that individuals taking fewer steps each day exhibited a higher risk of developing the condition. This correlation was particularly pronounced in the years immediately preceding a formal diagnosis, suggesting that decreased mobility might be an early symptom rather than a causal factor.
The study, which followed participants for an average of 7.9 years, controlled for various lifestyle and demographic factors. However, the researchers emphasized that the observed relationship does not imply step counts can diagnose Parkinson's. Instead, the findings add to evidence that wearable devices could help identify subtle, early changes in movement associated with the disease's prodromal phase.
While the study highlights the potential for technology in Parkinson's research, experts stress that reduced physical activity can stem from numerous health issues. They recommend adhering to general physical activity guidelines for overall health, noting that this research is more about understanding the early stages of Parkinson's than a diagnostic tool for the general public.
