Today, I review and link to the results of a Google Search: Parkinson’s Disease Rating Scales.

All that follows is from the above resource.

MDS Unified Parkinson's Disease Rating Scale (MDS-UPDRS ...

The primary rating scale for Parkinson’s disease is the Unified Parkinson’s Disease Rating Scale (UPDRS) and its updated version, the Movement Disorder Society-Sponsored Revision (MDS-UPDRS). Doctors use it as the global gold standard to measure the severity and progression of motor and non-motor symptoms. [1, 2, 3]

Structure of the MDS-UPDRS
The evaluation is split into four main parts, generally scored on a 0 to 4 scale (where higher numbers indicate greater severity): [1, 2]

  • Part 1 (Non-Motor Experiences of Daily Living): Evaluates cognitive function, depression, anxiety, hallucinations, sleep disorders, and pain. [1, 2]

  • Part 2 (Motor Experiences of Daily Living): Assesses self-reported practical tasks like speech, swallowing, handwriting, dressing, and walking. [1]

  • Part 3 (Motor Examination): A clinician-administered physical check of rigidity, tremors, facial expression, posture, gait, and slowing of movement. [1, 2]

  • Part 4 (Motor Complications): Evaluates treatment-related side effects such as dyskinesia (involuntary movements) and unpredictable “off” periods. [1, 2]
Complementary Scales

Clinicians often pair the UPDRS with other tools to get a complete picture: [1]

  • Hoehn and Yahr Scale: A 5-stage scale used to track how the physical symptoms progress from mild unilateral involvement (Stage 1) to severe disability requiring 24/7 care (Stage 5). [1]
