Recently identified brain rhythm during sleep may play a crucial role in clearing neurotoxic waste and protecting against dementia. Unlike wakefulness, when major neuromodulators such as norepinephrine, acetylcholine, serotonin, and dopamine act relatively independently, sleep synchronizes their activity into coordinated oscillations occurring approximately every 50 seconds. These rhythmic fluctuations are […]
A US community-based study found that middle-aged adults with blood biomarkers indicating Alzheimer’s disease neuropathology already showed worse cognition and faster cognitive decline years before dementia diagnosis. Researchers analyzed 1,350 participants from the Coronary Artery Risk Development in Young Adults (CARDIA) study who underwent plasma biomarker testing at year 35 […]
A randomized clinical trial found that a single 25 mg dose of psilocybin produced rapid antidepressant effects in patients with moderate to severe recurrent major depressive disorder (MDD), with benefits emerging by day 2 and persisting for more than 3 months on several secondary measures. Conducted at the Northern Stockholm […]
A US prospective real-world study of 357 adults with Irritable Bowel Syndrome (IBS) found that higher daily stress levels were strongly associated with worse IBS symptom severity, and stress and symptoms appeared to reinforce each other especially from the afternoon into the evening. Researchers followed adults meeting Rome IV criteria […]
A longitudinal study using data from the Alzheimer’s Disease Neuroimaging Initiative found that omega-3 fatty acid supplementation was associated with accelerated cognitive decline in older adults, challenging the common belief that omega-3 universally protects brain health. Participants taking omega-3 supplements showed faster worsening in MMSE, ADAS-Cog13, and CDR-SB scores over […]
Accelerometer-derived sleep-wake cycle patterns were associated with a higher risk of future dementia and modestly improved dementia prediction beyond traditional risk factors, with predictive value comparable to APOE genotype when added to an age-only model. In this large prospective cohort study involving more than 53,000 older adults from the UK […]
A US prospective study found that moderate egg consumption was associated with a significantly lower risk of Alzheimer’s disease, with participants eating eggs ≥5 times per week showing a 27% lower risk compared with those who rarely or never ate eggs. Researchers analyzed data from 39,498 participants in the Adventist […]
Anxiety disorders are common yet often underrecognized in primary care, but a review shows that cognitive-behavioral therapy (CBT), selective serotonin and serotonin-norepinephrine reuptake inhibitors (SSRIs/SNRIs), and collaborative care models can substantially improve outcomes. Current recommendations support anxiety screening for adults younger than 65 years, with assessment including symptom questionnaires, clinical […]
Two-dose recombinant zoster vaccination (RZV) was associated with a significantly lower risk of new-onset dementia, including Alzheimer’s disease (AD) and vascular dementia (VD), among U.S. adults aged 65 years or older. In this Medicare-based study, individuals who received RZV were matched to unvaccinated counterparts by age, sex, and race/ethnicity, all […]
Higher consumption of ultra-processed foods (UPFs) is associated with poorer attention and increased modifiable dementia risk, independent of overall diet quality. In this cross-sectional study of 2,192 dementia-free Australian adults aged 40–70 years, dietary intake was assessed using a validated food frequency questionnaire and categorized by the Nova classification system, […]
