Researchers tracked 32 people with early Parkinson’s disease for three years using wearable technology and annual qualitative interviews. Core motor symptoms-including tremor, stiffness, slow movement, and gait difficulties-remained relatively stable in perceived severity.
But functional impact escalated: participants reported steadily increasing effort required for daily activities by year three. Gait and balance were the only motor domains showing significant change; non-motor symptoms like fatigue and sleep disturbance remained prevalent but stable.
The findings challenge conventional clinical metrics-highlighting that patient-reported functional burden, not just symptom scores, must guide care. Adaptive coping strategies emerged over time, underscoring the value of personalized, supportive management.
