MDS-UPDRS Part I – Non-Motor Experiences of Daily Living
Non-motor experiences of daily living in Parkinson’s disease. 13 items, total 0 to 52.
By Claire White
- Completed by the patient (and partly by clinician); approximately 5 to 10 minutes.
- 13 items covering cognitive impairment, hallucinations, depressed mood, anxious mood, apathy, dopamine dysregulation, sleep, daytime sleepiness, pain, urinary problems, constipation, light-headedness, and fatigue.
- Each item 0 to 4; total 0 to 52 (0 = no impairment).
What it measures
Part I covers 13 non-motor symptoms experienced in daily life. Items 1.1 to 1.6 (cognitive impairment, hallucinations, delusions, depressed mood, anxious mood, apathy, dopamine dysregulation syndrome) are completed with clinician input. Items 1.7 to 1.13 (sleep problems, daytime sleepiness, pain, urinary problems, constipation, light-headedness, fatigue) are completed by the patient independently.
What the result tells you
Higher Part I scores indicate greater non-motor burden. Non-motor symptoms are often undertreated in Parkinson’s disease, and Part I quantifies them systematically. It is used in trials of symptomatic therapies and in longitudinal registry studies tracking disease progression.
