- Older adults tend to fall asleep during the day and the prevalence is 50%.
- Recurrent awakenings due to disrupted breathing leads to excessive sleep during the day.
- Obstructive Sleep apnea was more common in adults aged over 65 with cognitive impairment.
Sleep-disordered breathing (SDB), a disruption of normal breathing during sleep causes recurrent awakenings and subsequent excessive daytime sleepiness in the elderly.
Compared with younger adults, the elderly spend more time in bed but have deterioration in both the quality and quantity of sleep. A Boston University School of Medicine (BUSM) researcher stresses that it is now time for physicians to consider the association between these sleep conditions and cognitive impairment in the elderly.
In the same issue of the journal, researchers of the "HypnoLaus Study" investigated an older population (over the age of 65), with and without cognitive impairment. They performed sleep studies on these groups and found that the group with cognitive impairments had more sleep disturbances attributed to SDB.
According to Auerbach the causal link between SDB /obstructive sleep apnea (OSA) and cognitive impairment in the elderly is not entirely clear.
"Nevertheless, it does raise the issue that clinicians evaluating OSA in the elderly should screen for cognitive impairments. Furthermore, clinicians evaluating cognitive impairment in the elderly should also screen their patients for sleep disturbance and OSA."
Even though it is not clear that treatment of OSA will delay or prevent the cognitive impairment and possible development of dementia, Auerbach believes that treatment of OSA will certainly improve the quality of life for these patients.
