Topic: Risk, prevention and care in population studies
Cognitive impairment is one of the earliest, most common, and most disabling non-motor symptoms in Parkinson's disease (PD). Thus, routine screening of global cognitive abilities is important for the optimal management of PD patients. Few global cognitive screening instruments have been developed for or validated in PD patients.
Key findings
- Thus, routine screening of global cognitive abilities is important for the optimal management of PD patients.
- Few global cognitive screening instruments have been developed for or validated in PD patients.
- The Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Dementia Rating Scale-2 (DRS-2) have been used extensively for cognitive screening in both clinical and research settings.
- Determining how to convert the scores between instruments would facilitate the longitudinal assessment of cognition in clinical settings and the comparison and synthesis of cognitive data in multicenter and longitudinal cohort studies.
Why it matters
This cohort study worked out how to convert scores between the MMSE, Montreal Cognitive Assessment and Dementia Rating Scale-2 in Parkinson's disease. It is about comparing cognitive screening scores over time, not about treating, curing or preventing Alzheimer's disease.

How this study scored 61/100
Published in a peer-reviewed journal, and it is a cohort study following people over time. Scored zero for effect reported and randomised / blinded because the record does not state it.
