A 2026 meta-analysis of 4 randomized trials found that GLP-1 receptor agonists reduced obstructive sleep apnea severity by 13.89 apnea-hypopnea events per hour compared with placebo, alongside 12.46 kg more weight loss than placebo.1 The effect looks clinically meaningful for obesity-linked sleep apnea, but high heterogeneity means the result should not be flattened into “GLP-1 …
A 2026 automated MRI analysis of 153 adults with first cortical middle cerebral artery stroke found that remote deep gray nuclei changes were already measurable within 21 days, and 2 asymmetry markers independently predicted 3-month disability change: putamen volume Z-score asymmetry (β = −0.24; p = 0.021) and thalamic apparent diffusion coefficient asymmetry (β = …
A 2026 Australian study involving 2,192 dementia-free adults found that each 10% higher ultra-processed food intake was associated with 0.05-point lower attention and 0.24-point higher modified CAIDE dementia-risk score.1 The memory result was not significant, so the honest read is attention and risk-score signal, not global cognitive collapse. Research Highlights Attention was lower: Each 10% …
A 2026 mixed-methods study of group physical activity inside psychiatric treatment found that 90% of participants joined to have a healthy body and get fresh air, 97% felt supported by activity leaders, and 91% wanted to stay active with others after treatment.1 The useful message is not “tell people with severe mental illness to exercise”; …
A 70-person COPD trial found that 12 weeks of app-based rhythm-guided walking plus singing improved shuttle-walk distance by 56.35 m and lowered HADS-anxiety by 2.31 points vs. usual care; rhythm-guided walking without singing did not clearly separate from usual care.1 Research Highlights Combined training beat usual care: the multimodule group improved incremental shuttle walking test …
A 2026 meta-analysis of 8 controlled trials found that AVATAR therapy reduced auditory verbal hallucination severity after treatment, Hedges’ g = −0.40, 95% CI −0.54 to −0.25, across 978 participants.1 The signal is real, but the strongest reading is short-term symptom calibration rather than a finished replacement for standard psychosis care. Research Highlights Voice severity …
An iScience EEG study found that approximately 80 minutes of natural smartphone use was interleaved with transient beta bursts, especially over bilateral sensorimotor cortex, and touchscreen intervals became longer when sensorimotor bursts were present.1 Research Highlights Natural smartphone behavior carried beta bursts: participants used smartphones with the right thumb for approximately 80 minutes while EEG …
