A study found that sleep-like, high-amplitude slow waves intrude into wakefulness more often in adults with ADHD, correlating with more variable reaction times and more commission errors during a 52-minute attention task; researchers suggest waking slow waves may link sleep regulation to ADHD and could serve as a biomarker, though more replication is needed.
A Monash University-led study of more than 2,000 dementia-free Australians aged 40–70 found that each 10% rise in ultraprocessed food intake was associated with lower attention scores and higher dementia risk, even among people with generally healthy diets; memory effects were not observed. Self-reported data and potential confounding limit the strength of conclusions. Researchers and experts, including Dr. Daniel Amen, call for dietary guidelines to consider processing level and for replacing ultraprocessed foods with real foods to protect brain health.
A cross-sectional study of 2,192 dementia-free Australian adults finds that each 10% rise in ultra-processed food (UPF) intake is tied to lower visual attention scores and higher dementia risk, independent of overall diet quality. The impact persists even among those following a healthy Mediterranean pattern, suggesting that the degree of food processing itself may drive cognitive decline via additives and processing chemicals. The study shows association, not causation, but highlights attention as a foundation for learning and a potential early dementia risk factor.
A study from Australia and Brazil found that ultraprocessed foods can impair attention and cognitive processing speed after just one bag of chips, even in middle-aged adults whose overall diet contained about 41% ultraprocessed foods. The effect, observed in more than 2,100 participants, occurred within minutes and persisted despite otherwise healthy eating patterns like the Mediterranean diet. Researchers say additives and the degree of processing may drive this link, which aligns with prior work showing higher ultraprocessed intake associates with increased dementia risk factors (and a Harvard Medical School study suggesting a 25% higher dementia risk with higher ultraprocessed consumption). The findings highlight that not only nutrition but also ultra-processing itself may impact brain function.
A NIH-funded RECOVER study of 1,976 youths aged 6–17 found that long COVID is linked to worse post-pandemic grades, more difficulty concentrating, and reduced social engagement. School-aged children with long COVID showed 18% worse grades vs 7% without, while adolescents showed 29% vs 11%; concentration problems were 38% vs 14% in younger kids and 37% vs 11% in teens. AEP/IEP pursuit and diminished peer fun were more common in those with long COVID as well. The authors call for expanded school-based supports and targeted interventions to mitigate potential long-term developmental impacts.
Researchers found that adults with ADHD show more frequent sleep-like slow waves during wakefulness while performing attention-demanding tasks, and these bursts are linked to more errors, slower reaction times, and lapses in attention. The study compared 32 adults with ADHD off medication to 31 neurotypical controls. The findings suggest a brain mechanism behind ADHD-related attention difficulties, and future work may test whether sleep-based stimulation to boost slow waves could reduce daytime sleep-like activity and improve focus.
In a study of 63 adults (32 with ADHD, 31 controls), ADHD participants showed more sleep-like slow waves during a sustained attention task—especially in fronto-central brain regions—and these waves predicted missed responses and variable reaction times. The findings support the idea of 'local sleep' during wakefulness as a neural mechanism for ADHD inattention and point to sleep-based interventions and EEG biomarkers, though causality isn’t proven and the results come from a lab task.
New findings show localized sleep-like slow waves occur during wakefulness more often in adults with ADHD, correlating with attention lapses, slower reaction times, and daytime sleepiness, and suggesting a potential nonpharmacological treatment using auditory stimulation to enhance deep sleep and reduce daytime intrusions.
Constant, personalized soundscapes subtly shape how we think by steering attention and mental effort; lyrics can disrupt language tasks, while familiar, simpler sounds may support repetitive work. The piece offers three principles—match the sound to the task, monitor your own signals to adjust audio, and protect silence—and practical tips to design a listening environment that boosts focus and recovery rather than hijacking thinking, with implications for sleep and daily life.
A synthesis of 100+ brain-imaging studies shows that short time in nature triggers a neural reset—reducing amygdala activity, easing sensory processing via fractal patterns, restoring attention, and quieting repetitive self-talk—effects that deepen with longer, real-world immersion and support nature-based health strategies like green design and social prescribing.
MIT researchers found that after sleep deprivation, brief attention lapses coincide with cerebrospinal fluid moving out of the brain—an event normally seen during sleep to clear waste. The brain appears to enter a sleep-like state during wakefulness to restore function, trading attention for fluid flow, with slowing breathing, lower heart rate, and pupil constriction; EEG/fMRI data from 26 volunteers point to the noradrenergic system, and findings were published in Nature Neuroscience.
Despite being always in your field of view, your nose largely disappears from conscious sight because the brain habituates to constant stimuli and filters out familiar inputs, so you only notice it if you deliberately focus on it or change your viewpoint.
A practical plan to rebuild attention spans: first, audit when and why your mind wanders; second, reduce distractions with small frictions, intentional breaks, and task planning; third, extend focus through mindfulness practice, deliberate breaks, nature time, and structured work rituals like batching interruptions.
A meta-analysis shows that physical activity, especially cognitively complex sports like basketball or dance, significantly improves attention and focus, serving as a natural alternative or supplement to medication for attention-deficit disorder. Regular moderate exercise enhances brain function by increasing blood flow and releasing beneficial proteins, with timing and enjoyment being key factors for maximizing benefits.
New research shows that ADHD drugs like Adderall and Ritalin do not directly improve attention but instead increase brain arousal and the feeling of reward, making tasks seem more interesting and easier to focus on. The drugs primarily affect brain regions related to wakefulness and motivation, and their effectiveness can be influenced by sleep quality. This challenges previous beliefs about how these medications work and suggests a need to reevaluate their role in treating ADHD.
