Wide variation in UK sleep disorders services which doesn't match need

The UK's sleep disorder services are severely lacking, with high rates of obstructive sleep apnea (OSA) in certain regions going undiagnosed and untreated. Despite the rising demand due to an aging population, many areas have limited access to specialized care, leading to a concerning mismatch between need and supply.

Investigational drug improves sleep disorder among the blind

A study found that patients taking tasimelteon had a significantly higher rate of re-synchronization of their body clock, leading to improved night-time sleep and reduced daytime drowsiness. The medication addresses the root cause of Non-24 Hour Sleep-Wake Disorder in blind individuals by synchronizing their circadian clock.

Acting out dreams linked to development of dementia, Mayo Clinic study finds

A Mayo Clinic study found that men with dementia with Lewy bodies are five times more likely to have rapid eye movement (REM) sleep behavior disorder, which can appear decades before a diagnosis. The study suggests that screening for this sleep disorder could improve diagnosis and treatment of dementia with Lewy bodies.

Overactive bladder linked to sleep apnoea in women

Researchers found a significant link between sleep apnoea and overactive bladder syndrome in women, with symptoms of urgency, frequency, and nocturia prevalent among those diagnosed with sleep apnoea. The study suggests that continuous positive airway pressure therapy may help alleviate bladder control issues.

Salk scientists redraw the blueprint of the body's biological clock

Researchers at Salk Institute find that two cellular switches play a crucial role in maintaining normal sleeping and eating cycles and metabolism. The discovery suggests a powerful link between circadian rhythms and metabolism, potentially leading to new treatments for disorders such as sleep problems, obesity, and diabetes.

Study: Sleep gets better with age, not worse

A new survey of over 150,000 Americans shows that subjective sleep quality improves over a lifetime, with women reporting more sleep disturbances than men. Health problems and depression are associated with poor sleep, but except for an uptick during middle age, sleep quality consistently improves with age.

REM sleep behavior disorder is a risk factor for Parkinson's disease

Patients with REM sleep behavior disorder experience nightmares and increased risk of developing Parkinson's disease. A new study using brain SPECT technology found that dopamine levels in the brain drop quickly in these patients, making it a potential early indicator of disease progression.

Through evolution, cavefish have lost sleep

Researchers studying Mexican Blind Cave Fish found that cave-adapted fish sleep less and are more active than their surface-dwelling relatives. The discovery suggests that the transition to a dark environment may be associated with changes in sleep behavior, potentially due to the need for continuous vigilance to find food.

Sleep-deprived people make risky decisions based on too much optimism

A study found that sleep deprivation leads to increased activity in brain regions assessing positive outcomes and decreased activity in those processing negative outcomes. As a result, sleep-deprived individuals are more likely to choose options with potential gains over those with potential losses.
