Short sleep duration and dementia: a narrative review
Emily R Stephens, Ashish Sarangi, Jayasudha Gude. Proceedings (Baylor University. Medical Center), 2022-01-31
Topic: Brain imaging, connectivity and assessment
Short sleep duration has been linked to the development of neurocognitive disorders. Still, current evidence for this relationship is conflicting. In this review, we summarize evidence regarding the relationship between short sleep duration and neurocognitive disorders, which shows that short sleep duration increases the risk of incident major neurocognitive disorders beginning as early as midlife. The pathological brain changes attributed to poor sleep may be related to changes in brain microstructure and accumulation of debris in the brain. More evidence is needed to fully understand the relationship between sleep duration and cognitive decline and the molecular changes that link the two. Measures of sleep quality such as sleep duration represent a potentially modifiable risk factor for the prevention of cognitive decline and neurocognitive disorders.

How this study scored 41/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people 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, multi-centre collaboration and free to read, so those were left out: it earned 23 of the 56 points we could judge it on, which is 41 out of 100.
