Researchers have found a genetic link between the nighttime production of the sleep hormone melatonin and ADHD symptom severity in children. The study enhances our understanding of the complexities associated with this prevalent neurodevelopmental condition. Sleep disturbances, including insomnia, restless sleep, and daytime drowsiness, are common in people with attention-deficit hyperactivity disorder, or ADHD. It’s been hypothesized that people with the condition have a disrupted circadian rhythm. However, the exact mechanism connecting sleep problems and ADHD has remained elusive. A new study led by the Nagoya University Graduate School of Medicine in Japan may have provided the answer. The researchers...

A common sleep aid restores healthier sleep patterns and protects mice from the brain damage seen in neurodegenerative disorders, such as Alzheimer's disease, according to new research. The drug, lemborexant, prevents the harmful buildup of an abnormal form of a protein called tau in the brain, reducing the inflammatory brain damage tau is known to cause in Alzheimer's. The study suggests that lemborexant could help treat or prevent the damage caused by tau in multiple neurodegenerative diseases, including Alzheimer's, progressive supranuclear palsy, corticobasal syndrome and some frontotemporal dementias. "In this new study, we have shown that lemborexant improves sleep and...

Scientists have long recognized the brain's need for energy, but new research has now illuminated how the brain's energy utilization significantly influences our sleep patterns. The team discovered certain channels in the brain, called ATP-sensitive potassium (KATP) channels, act as energy sensors and play a pivotal role in maintaining stable sleep-wake cycles and facilitating smooth transitions between cycles. "Our study shows that even small changes in energy usage can profoundly impact behavior," said Macauley. These changes impact when we sleep, how we sleep and the overall quality of our sleep. The study identified a previously unknown function of KATP channels...

Poor sleep among older adults is linked to disruptions in the brain's "waste removal system," according to researchers. A recent study offers valuable insight into how sleep quality impacts brain functioning. Many studies have linked poor sleep with a decline in brain functioning. Professor Lee's team focused on the glial-lymphatic (glymphatic) system, a fluid transport pathway that plays a vital role in clearing waste from the brain. The system's efficiency is a critical determinant of brain health, particularly in aging populations. Professor Lee and her team sought to understand the glymphatic-brain relationship in poor sleepers, which underlies memory decline. Dysfunction...

Research has found that inadequate sleep duration and late sleep onset are associated with increased glycemic variability in adults. Blood sugar regulation plays a critical role in metabolic health, with fluctuations in glucose levels linked to diabetes complications. Previous research has identified insufficient sleep as a risk factor for impaired glucose metabolism. In the study, researchers conducted a prospective cohort study to evaluate the relationship between long-term sleep duration and onset timing with glycemic variability. The study analyzed 1,156 participants, aged 46 to 83, from the Guangzhou Nutrition and Health Study. Participants underwent self-reported sleep assessments across multiple visits and...

Resistance or muscle-strengthening exercise, using weights or the body itself, may be the best type of exercise for tackling insomnia in older age, suggests a pooled data analysis of the available research. Aerobic exercise or a mix of strength, aerobic, balance, and flexibility exercises also seem to be effective. The researchers scoured research databases for relevant clinical trials, published up to October 2022, that compared physical exercise with routine activities, usual care, other non-physical activity, or health education in people formally diagnosed with insomnia, using the Global Pittsburgh Sleep Quality Index (GPSQI). The types of exercise covered by the studies...

Amber Monaghan’s journey into sound healing wasn’t just a career shift—it was a calling. Decades ago, she experienced what she describes as a spiritual awakening, one that sent electrical sensations through her body and left her searching for answers. That search led her to Dr. Jeffrey Thompson, founder of the Neuroacoustic Research Foundation in San Diego, and his work in therapeutic audio research. Thompson had developed a method of recording personalized sounds said to shift the nervous system from a state of stress and imbalance into a space of deep healing, emotional release and spiritual clarity. From the moment Monaghan...

Blue-enriched light can improve sleep quality and daily activity in older adults living at home, according to new research. Researchers found that this type of light therapy led to greater daytime activity, earlier bedtimes, regular sleep patterns and improved sleep quality, offering a promising, non-pharmacological approach to address age-related sleep challenges. As people age, their sleep patterns often change, leading to difficulties falling asleep, waking up earlier, more frequent nighttime awakenings, and overall poorer sleep quality. These changes are linked to age-related changes in the eyes and reduced exposure to daylight, often due to decreased mobility and social interactions, alongside...

New research reveals insight into the impact sleep quality has on a person's immune system, and how it could be linked to the development of diseases such as obesity, diabetes, and cardiovascular diseases. The study found that even a single night of 24-hour sleep deprivation in young, lean, and healthy individuals altered the profile of immune cells that help regulate the immune system to resemble that of individuals with obesity—a condition known to drive chronic inflammation. This suggests that the immune system is highly sensitive to sleep and may adapt rapidly to changes in sleep pattern. According to the researchers,...

Getting enough quality sleep is essential for maintaining overall health. It supports better brain function, strengthens the immune system, and promotes a healthy heart. On the other hand, sleep disorders like insomnia and sleep apnea can harm both health and quality of life. Poor sleep has also been linked to the early onset of neurodegenerative diseases and can serve as an early warning sign of dementia. ---SNIP--- The study also holds a warning for people who use the commonly prescribed sleep aid zolpidem. The drug suppressed the glymphatic system, potentially setting the stage for neurological disorders like Alzheimer’s, which are...

The short-term boost our brains get after we do exercise persists throughout the following day, suggests a study. The study found that, on average, people aged 50 to 83 who did more moderate to vigorous physical activity than usual on a given day did better in memory tests the day after. More deep (slow-wave) sleep also contributed to memory function, and the research team found this accounted for a small portion of the link between exercise and better next-day memory. The research team looked at data from 76 men and women who wore activity trackers for eight days and took...

Around 15 percent of the world's population suffers from tinnitus, a condition which causes someone to hear a sound (such as ringing or buzzing) without any external source. It's often associated with hearing loss. Not only can the condition be annoying for sufferers, it can also have a serious effect on mental health, often causing stress or depression. This is especially the case for patients suffering from tinnitus over months or years. There's currently no cure for tinnitus. So finding a way to better manage or treat it could help many millions of people worldwide. And one area of research...

A study has linked low levels of oxygen in the blood overnight—a common sign of obstructive sleep apnea—with wet age-related macular degeneration. The findings suggest obstructive sleep apnea (OSA) could be a modifiable risk factor associated with the "wet" form of late-stage age-related macular degeneration (AMD). The team conducted a sleep study involving 225 participants aged over 50 with different stages of AMD and measured their oxygen levels over three nights with a home-based finger oximeter. Their level of OSA was calculated based on the oxygen levels in their blood overnight. The results showed that moderate-to-severe OSA, which results in...

Researchers have discovered that changes in sleep patterns as we age are associated with lower odds of successful aging. In the study, researchers analyzed 3,306 participants who were free of major chronic diseases at baseline in 2011 and had reached age 60 or older by 2020. Sleep duration was assessed in 2011, 2013, and 2015 by combining nighttime sleep and daytime naps to calculate total daily sleep hours. The researchers identified five distinct sleep duration trajectories over the nine-year period: normal-stable (26.1% of participants), long-stable (26.7%), decreasing (7.3%), increasing (13.7%), and short-stable (26.2%). Logistic regression models adjusted for factors like...

Some say the early bird catches the worm, while some studies suggest that night owls have better cognitive function (intelligence, reasoning, and memory) compared to early risers. Personally, I'm not a huge fan of rising early. You'd think that after waking up early all my life — first as a student and then as a mum — I'd be used to it by now. But nope, I firmly belong to the sleep-in brigade. Are you an "Early to bed, early to rise" sort, or a "Stay up late and sleep in" night owl? If you're not an early bird, check...
