Sumary of Having trouble falling asleep associated with cognitive impairment 14 years later:
- A study of nearly 2,500 adults found that having trouble falling asleep, as compared to other patterns of insomnia, was the main insomnia symptom that predicted cognitive impairment 14 years later..
- Specifically, more frequent trouble falling asleep predicted poorer episodic memory, executive function, language, processing speed, and visuospatial performance..
- Further analysis found that associations between sleep initiation and later cognition were partially explained by both depressive symptoms and vascular diseases in 2014 for all domains except episodic memory, which was only partially explained by depressive symptoms..
- While there is growing evidence for a link between insomnia and cognitive impairment in older adults, it has been difficult to interpret the nature of these associations given how differently both insomnia and cognitive impairment can present across individuals..
- By investigating associations between specific insomnia complaints and cognition over time using strong measures of cognitive ability, we hoped to gain additional clarity on whether and how these different sleep problems may lead to poor cognitive outcomes.”.
- In 2016 the participants’ cognition was assessed as part of the Harmonized Cognitive Assessment Protocol and operationalized with a comprehensive neuropsychological battery tapping episodic memory, executive function, language, visuoconstruction, and processing speed..
- These results suggest that regular screening for insomnia symptoms may help with tracking and identifying people with trouble falling asleep in mid-to-late life who might be at risk for developing cognitive impairments later in life…
