          Shared Brain Circuit Links Insomnia, Anxiety, and Depression

          A large brain imaging study suggests that insomnia, depression, and anxiety—often co-occurring—share overlapping brain abnormalities. Researchers found reduced cortical surface area, smaller thalamic volume, and weaker brain connectivity across all three disorders, while each also displayed unique neural patterns.

          What Poor Sleep Really Does to Your Brain

          Chronic sleep disorders and short-term sleep deprivation affect different regions of the brain, highlighting distinct neural impacts. A meta-analysis of 231 brain studies showed that chronic sleep disorders alter regions involved in emotions and memory, while short-term deprivation primarily affects attention and movement regulation.

          Screen Time in Bed Linked to Less Sleep, Higher Insomnia Risk

          A new study of over 45,000 young adults found that using screens in bed increases the risk of insomnia by 59% and cuts sleep by 24 minutes. Surprisingly, the type of activity—whether social media, movies, or studying—didn’t make a difference; it was the screen time itself that mattered most.

          Sleep-Deprived Fruit Flies Show Sharper Memory via PKA Signaling

          Fruit flies with genetic mutations that severely reduce sleep show enhanced performance in olfactory memory tasks, challenging assumptions about sleep’s role in cognition. This paradox appears to be driven by increased protein kinase A (PKA) signaling in the mushroom body, a brain region responsible for memory and sleep regulation.

          Poor Sleep Linked to Difficulty Controlling Unwanted Thoughts

          Sleep deprivation impairs brain regions responsible for suppressing unwanted thoughts, contributing to mental health challenges. Functional neuroimaging revealed reduced activation in the prefrontal cortex and increased hippocampal activity in sleep-deprived individuals, suggesting memory control deficits.

          Lack of Sleep in Childhood Linked to Increased Psychosis Risk

          Children who consistently experience insufficient sleep from infancy through early childhood are significantly more likely to develop psychosis as young adults. Analyzing data from the Avon Longitudinal Study of Parents and Children, researchers found that chronic sleep deprivation is a strong predictor of both psychotic disorders and psychotic episodes later in life.

          Children and teens from racial and ethnic minority groups, especially Black children, are more likely to suffer from insomnia that begins in childhood and persists into adulthood. The study underscores the chronic nature of insomnia symptoms starting from a young age and their link to significant health issues, including cardiometabolic diseases and mental health disorders.

          Researchers unveiled a link between sleep quality and subjective age, demonstrating that insufficient sleep can make individuals feel significantly older. Through two studies involving over 600 participants, they found that each night of inadequate sleep contributed to feeling 0.23 years older, with sleep restriction causing participants to feel on average 4.4 years older.

          Distinct Sleep Patterns Linked to Health Outcomes

          Researchers have identified four distinct sleep patterns linked to long-term health outcomes, revealing the profound impact of sleep habits on chronic health conditions. Utilizing data from the Midlife in the United States study, the team found that "insomnia sleepers" and "nappers" dominate the population, with insomnia sleepers facing a higher risk of chronic illnesses like cardiovascular disease, diabetes, and depression over a decade.

          unveiled the science behind the buoyant mood many feel after acute sleep deprivation, like pulling an all-nighter. The study in mice showed that not only does dopamine release rise during these short periods without sleep, but the brain also rewires itself, enhancing synaptic plasticity for several days.

          How Sleep Loss Amplifies Pain

          Researchers discovered how sleep deprivation can exacerbate pain. Their study demonstrates that a neurotransmitter, N-arachidonoyl dopamine (NADA), decreases in a brain region called the thalamic reticular nucleus (TRN) due to sleep loss.
