The<unk> <unk>  is used to follow the longitudinal course of<unk> 's disease. The UPD<unk><unk>  is the most commonly used<unk>  in the clinical study of<unk> 's disease. The<unk>  is made up of these sections: *Part I: evaluation of mentation, behavior, and mood *Part II: self-evaluation of the activities of daily life (ADLs) including speech, swallowing, handwriting, dressing, hygiene, falling, salivating, turning in bed, walking, and cutting food *Part III: clinician-scored monitored motor evaluation *Part IV: complications of therapy *Part V: Hoehn and Yahr staging of severity of<unk> 's disease *Part VI: Schwab and England ADL<unk>  These are evaluated by interview and clinical observation. Some sections require multiple grades assigned to each extremity. Clinicians and researchers alike use the<unk>  and the motor section in particular to follow the progression of a person's<unk> 's disease. Scientific researchers use it to measure benefits from a given therapy in a more<unk>  and accepted<unk>  system. Neurologists also use it in clinical practice to follow the progression of their patients' symptoms in a more objective manner. Following the<unk>  scores over time provides insight into the patient's disease progression. For instance Michael J. Fox's symptoms started with a slight tremor, so his motor score would have been less than 10. For most patients, the "mentation, behavior and mood" scores increase later in the disease, but a subset exists for whom those symptoms develop early on.
