A study found that older adult dementia caregivers have significantly worse sleep patterns than non-caregivers, with less total sleep time and increased daytime sleepiness. Caregivers also reported lower subjective sleep quality and higher depressive symptom scores.
A 14-year follow-up study found that individuals with moderate to severe obstructive sleep apnea had a significantly higher mortality rate compared to those with mild OSA or no sleep apnea. The study, which involved a community-based sample of adults, provides strong evidence linking sleep apnea to all-cause mortality.
A study found that people with severe sleep apnea have a much higher mortality risk than those without, with an adjusted hazard ratio of 3.2. Regular CPAP use may protect against cardiovascular death, but the mechanisms are unclear.
Research suggests a strong association between depression, sleep deprivation, and suicidal behavior in children and adolescents. Sleep complaints during depressive episodes can be an indicator of suicidal behavior, particularly in pediatric bipolar disorder patients.

A study by the University of Chicago found that restricting bedtime led to increased energy from snacks, including more carbohydrates. This behavior may be driven by changes in reward-seeking and motivation. Getting adequate sleep is essential for maintaining a healthy weight.
Research finds a strong correlation between migraines and sleep disorders in children, including obstructive sleep apnea (OSA) and tooth grinding. Children with migraines are twice as likely to have OSA and experience shorter REM sleep, highlighting the importance of addressing sleep issues in pediatric headache management.
A study published by the American Academy of Sleep Medicine found that children with Down Syndrome have more fragmented sleep and frequent awakenings compared to typically developing children. The study suggests that this may be an independent issue and may impact cognitive, behavioral, and physical growth.
A recent study has found that increased fat intake is associated with lower REM sleep, higher arousal and apnea-hypopnea indexes, and reduced sleep efficiency. Healthy adults who consume high amounts of fat before bed may experience negative effects on their sleep patterns.
A recent study found that prenatal drug exposure is associated with greater sleep problems in children. Early sleep problems also predict later sleep problems, and nicotine has a unique effect on sleep patterns.
A study of 215 children found that those with bigger neck sizes are more likely to have a sleep-related breathing disorder, with predicted neck size correlating strongly with apnea-hypopnea index. This suggests that neck size should be considered in the clinical evaluation of children with snoring and apnea.
A study of 1,956 pre-schoolers found that tooth grinding during sleep was associated with worse pre-school adjustment, including social withdrawal and behavioral issues. Parents' reports of tooth grinding may be a sensitive indicator of bruxism in young children.
