Cognitive executive function in Down's syndrome
Rowe J, Lavender A, Turk V.. The British journal of clinical psychology, 2006-03-01
Topic: Brain imaging, connectivity and assessment
Objectives The study investigated executive function in adults with Down's syndrome. Design Participants with Down's syndrome (N=26) were compared with non-Down syndrome learning disabled participants (N=26). Method The two group's performance on a range of tests of executive function were compared. Groups were matched on age and a measure of vocabulary. Results The Down's syndrome group performed at a significantly lower level on a number of tests of executive function. Conclusion It is suggested that impaired executive function in Down's syndrome is due to abnormal development of the prefrontal cortex in Down's syndrome. Tests of executive function may be sensitive to cognitive changes with the onset of dementia in people with Down's syndrome. Longitudinal studies examining changes in executive function in people with Down's syndrome are recommended.

How this study scored 59/100
Published in a peer-reviewed journal, and it is a longitudinal study following the same people over time. Scored zero for effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 34 of the 58 points we could judge it on, which is 59 out of 100.
