Insufficient and Excessive Sleep Associated With Faster Cognitive Decline
Both insufficient and excessive sleep are associated with faster cognitive decline compared with sleeping approximately 7 hours per night.
Cognitive Impairment
Insomnia-Linked Short Sleep Duration Associated With Cognitive Impairment
Insomnia with objective short sleep duration has been previously associated with adverse cardiometabolic health outcomes, as well as poorer cognitive performance in otherwise noncognitively impaired adults. However, studies demonstrating an increased prevalence of cognitive impairment in this insomnia phenotype are lacking.
Inverted U-Shaped Link Seen for Sleep Duration, Cognitive Decline
There is an inverted U-shaped association between sleep duration and global cognitive decline.
Cerebrovascular Reactivity Predicts Cognitive Impairment Independent of AD
MRI-based cerebrovascular reactivity is associated with cognitive function independent of Alzheimer disease pathology.
Sleep, Cognition May Be Closely Linked in People With Bipolar Disorder
Sleep abnormalities and cognition in bipolar disorder may be related, and may affect cognition in this patient population.
Frontal Lobe Cognitive Dysfunction Symptom Reduction Associated With Rotigotine Therapy
Researchers conducted a randomized clinical trial to assess whether 24 weeks of treatment with rotigotine can modify cognitive functions in patients with mild to moderate Alzheimer disease.
Left Atrial Enlargement With AF Not Associated With Greater Cognitive Decline
Left atrial enlargement with vs without atrial fibrillation was not found to be associated with greater cognitive decline over a 5-year period.
Economic Hardship Results in Reduced Cognitive Function
Data emphasize the impact of poverty on certain aging outcomes, notably physical performance, cognitive ability, and systemic inflammation.
Cortisol Levels May Contribute to Global Cognitive Decline in Elderly Adults With Depression
These data indicate that cortisol levels may contribute to the cognitive decline observed in elderly adults with late-life depression.

These findings have high clinical relevance because patients with apathy are likely to withdraw from care.
