The body signals in advance? How to identify signs of Parkinson's years before diagnosis

A new study found that changes in walking, such as a slower pace and fewer steps, may predict Parkinson's up to seven years before diagnosis. Researchers identified five key changes by analyzing data from over 100,000 people. Early diagnosis allows lifestyle changes, but there is no cure.

A new study published in the Journal of Neural Transmission found that changes in walking patterns may predict the development of Parkinson's disease up to seven years before official diagnosis. Researchers analyzed data from over 100,000 people using motion-tracking bracelets and identified five key changes: fewer steps per day, a slower pace, shorter walking segments, irregular step rhythm, and reduced arm movement. The disease affects the central nervous system and disrupts signals from the brain to muscles, causing tremor, slow movement, stiffness, and instability. The article emphasizes that there is no cure to stop the disease, but early diagnosis allows adopting lifestyle changes, mainly regular physical activity, which may slow progression. It is recommended to consult a doctor if such changes are noticed, but not to panic, as walking problems can stem from a variety of other neurological conditions.
