Topic: Risk, prevention and care in population studies
Cognitive impairment is common in Parkinson's disease (PD). There is a critical need for a brief, standard cognitive screening measure for use in PD trials whose primary focus is not on cognition. The Parkinson Study Group (PSG) Cognitive/Psychiatric Working Group formed a Task Force to make recommendations for a cognitive scale that could screen for dementia and mild cognitive impairment in clinical trials of PD where cognition is not the primary outcome.

Key findings
- There is a critical need for a brief, standard cognitive screening measure for use in PD trials whose primary focus is not on cognition.
- The Parkinson Study Group (PSG) Cognitive/Psychiatric Working Group formed a Task Force to make recommendations for a cognitive scale that could screen for dementia and mild cognitive impairment in clinical trials of PD where cognition is not the primary outcome.
- This Task Force conducted a systematic literature search for cognitive assessments previously used in a PD population.
- Scales were then evaluated for their appropriateness to screen for cognitive deficits in clinical trials, including brief administration time (<15 minutes), assessment of the major cognitive domains, and potential to detect subtle cognitive impairment in PD.
Why it matters
A Parkinson Study Group task force reviewed the literature to recommend a brief cognitive screening scale for Parkinson's disease trials where cognition is not the main outcome. It is about measuring cognition in trials, not about treating, curing or preventing Alzheimer's disease.

How this study scored 46/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomized / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 44 of the 96 points we could judge it on, which is 46 out of 100.
