A 2026 study of 250 mothers of children with intellectual and developmental disabilities (IDDs) found that family burden was strongly tied to lower social support, lower family quality of life, and lower happiness. In the structural model, the burden-happiness link was explained by perceived support and family quality of life rather than a direct burden-to-happiness …
A 2026 longitudinal study found reassuring cognitive trajectories after mild-to-moderate COVID-19: Alpha/Delta and Omicron groups both improved by follow-up, and neither group showed persistent neuropsychological test deficits vs. population norms. Psychiatric symptoms and fatigue were also broadly similar across variants.1 Research Highlights 55 adults were assessed: 27 were infected during the Alpha/Delta era and 28 …
Daytime agitation in dementia fluctuates day-to-day, and a 2026 explanatory study from Liu et al. used contactless under-mattress sensors in 55 long-term-care residents and an external 17-person home-monitoring cohort to show that lower nocturnal respiratory rate and higher activity instability robustly predict next-day agitation occurrence — but not severity.1 Research Highlights Lower breathing rate: adjusted …
A 2026 behavioral-variant frontotemporal dementia MRI study found that simple visual ratings of orbitofrontal and frontoinsular brain atrophy helped separate probable from possible bvFTD, with baseline left orbitofrontal atrophy predicting 3.77-fold higher odds of probable bvFTD classification.1 Research Highlights 143 people were rated: the study included 93 probable bvFTD cases, 15 possible bvFTD cases, and …
A 2026 community survey of 945 older adults in Nepal's Far-Western Sudurpaschim Province found geriatric depression in 43.9% of participants and a strong inverse link between depression scores and quality of life. The clearest adjusted predictors were age 75 or older and hill-region residence, while income and sex weakened after multivariable adjustment.1 Research Highlights Depression …
Coffee is widely framed as cognitively friendly, but a 2026 prospective study from Boscaini et al. published in Nature Communications used shotgun metagenomics, metabolomics, and cognitive testing in 62 healthy adults to show that coffee drinkers and non-coffee drinkers differ on the gut microbiome, key neurotransmitter-related metabolites, and behavioral measures — with coffee drinkers showing …
Resting-state fMRI studies of postpartum depression have produced inconsistent results for years. A 2026 voxel-based meta-analysis pooled 12 studies of 475 patients and found 4 reliable regional differences (amygdala, precuneus, occipital, precentral cortex) at uncorrected thresholds, none of which held up under strict family-wise error correction.1 Research Highlights 12-study fMRI pool: Chen et al. analyzed …
