In patients with Obstructive Sleep Apnea (OSA), cognitive and depressive symptoms are linked to dysfunctional connectivity within the posterior default mode network (DMN) and its disconnection from the frontoparietal network.
For OSA patients, cognitive issues like memory loss or brain fog are not just because they are tired; they are linked to changes in the brain's 'default mode network'. This highlights the importance of consistent OSA treatment (like CPAP) to potentially reverse or mitigate these network disruptions, and suggests that cognitive symptoms may persist even if daytime sleepiness is managed.
dysfunctional connectivity of the posterior default mode network appears to underlie cognitive and depressive symptoms of obstructive sleep apnoea
Why this rating
Supported by multiple rs-fMRI studies (seed-based FC, ICA, ReHo) showing consistent DMN alterations in OSA patients.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
