Some sleep apnea patients stay sleepy even when their CPAP is used 6+ hours a night and apnea events have been driven back to normal range. A 2026 cross-sectional study of 65 PAP-adherent adults found those residually sleepy patients performed measurably worse on global cognition, memory, executive function, attention, and processing speed than their well-rested …
Patients with chronic insomnia frequently end up on both a sleep medication and cognitive behavioral therapy for insomnia (CBT-I), and a 2026 AASM meta-analysis of 15 RCTs from Buysse et al. found a clear asymmetry: adding CBT-I to medication helps, while adding medication to CBT-I adds little and may even worsen daytime depression scores.1 Research …
A 2026 Shanghai study of 1,589 preschoolers found that children sleeping ≤9 hours at night had higher parent-rated anxiety scores than children sleeping >10 hours. The effect sizes were small, but the pattern appeared across total anxiety, physical injury fears, social phobia, obsessive-compulsive symptoms, and generalized anxiety symptoms.1 Research Highlights 1,589 preschoolers were analyzed: Zhang …
A 2026 arterial spin labeling MRI study found that 34 patients with non-auditory tinnitus and cerebral venous congestion had lower corrected cerebral blood flow across multiple brain regions than venous-congestion patients without tinnitus and healthy controls.1 Compared with those 2 groups, the tinnitus group had poorer sleep quality, higher depression scores, and slightly lower cognitive …
A 2026 scoping review screened 174 records and found 7 human studies linking sleep bruxism with gastroesophageal reflux disease.1 The signal was consistent but messy: case-control studies reported roughly 5- to 6-fold higher odds of bruxism with GERD, while instrumental studies suggested reflux episodes, arousals, swallowing, and jaw-muscle bursts may cluster during sleep. Research Highlights …
Popular coverage of chronotype neuroimaging usually claims that late chronotypes (evening types, often called “night owls”) show smaller cortical regions and faster brain aging than early chronotypes (morning types). A 2026 multimodal structural MRI analysis from Beheshti and Elkana ran the comparison in 136 healthy young adults using strict whole-brain correction, and the group differences …
A 2026 randomized trial in early postmenopausal women found that 8 weeks of app-based combined aerobic and resistance exercise reduced Beck Depression Inventory scores by 7.30 points, compared with 2.20 points after education-only control and 5.65 points after face-to-face exercise. A structured home program delivered through a mobile platform improved depression, fatigue, sleep quality, and …
