Sleep disorders, like insomnia and sleep-disordered breathing (SDB), significantly impact cognitive function. This review explores sex-specific effects of sleep disorders on cognitive impairment and dementia risk.
Area of Science:
- Neuroscience
- Sleep Medicine
- Gerontology
Background:
- Sleep is vital for health, and sleep disorders disrupt its quality and duration.
- Common sleep disorders include insomnia and sleep-disordered breathing (SDB).
- Sleep disorders are linked to medical and mental health conditions, notably cognitive dysfunction.
Purpose of the Study:
- To review how sleep disorders affect cognitive impairment.
- To explore sex-specific consequences of sleep disorders as a dementia risk factor.
- To investigate potential underlying mechanisms and suggest future research directions.
Main Methods:
- Narrative review of existing literature.
- Examination of the relationship between sleep disorders and cognitive function.
- Analysis of sex differences in sleep disorder-related cognitive changes.
Main Results:
- Sleep disorders are established risk factors for cognitive dysfunction.
- The precise mechanisms linking sleep disorders to cognitive decline are not fully understood.
- Sex differences in how sleep disorders affect cognition and dementia risk require further investigation.
Conclusions:
- Sleep disorders significantly impact cognitive health.
- Understanding sex-specific mechanisms is crucial for targeted interventions.
- Further research is needed to elucidate the complex interplay between sleep, sex, and cognition.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
