Grandparents who provided childcare for their grandchildren scored higher on tests of memory and verbal fluency than those who did not, according to research published in the American Psychological Association’s journal *Psychology and Aging*. The study, based on long-running survey data in England, found the association held regardless of how often grandparents helped or what kinds of caregiving tasks they performed.
Talking to oneself out loud is a common habit that many people practice at home or while walking, and psychology views it as an external expression of internal dialogue. This phenomenon helps organize ideas, make decisions, and regulate emotions, without being a sign of mental imbalance. It only raises concern if it interferes with daily life or accompanies other symptoms.

A new brain imaging study has found that recalling facts and personal experiences activates nearly identical neural networks, challenging long-held views on memory systems. Researchers from the University of Nottingham and University of Cambridge used fMRI scans on 40 participants to compare these memory types. The results, published in Nature Human Behaviour, suggest a rethink in how memory is studied and could inform treatments for Alzheimer's and dementia.
Researchers at Karolinska Institutet have identified how alpha oscillations in the brain help distinguish the body from the surroundings. Faster alpha rhythms enable precise integration of visual and tactile signals, strengthening the feeling of bodily self. The findings, published in Nature Communications, could inform treatments for conditions like schizophrenia and improve prosthetic designs.

A large-scale international study has found that age-related memory decline stems from broad structural changes across the brain, rather than a single region or gene. Analyzing over 10,000 MRI scans from thousands of healthy adults, researchers observed that brain shrinkage's impact on memory intensifies nonlinearly in later life. The findings highlight a distributed vulnerability that accelerates memory loss once a tipping point is reached.
In a Jan. 2, 2026 post on Wellness Mama, founder Katie Wells argues that irritation with other people’s behavior can sometimes point to unresolved issues within ourselves. She suggests that approaching these moments with curiosity—rather than blame—can support emotional regulation, empathy and a greater sense of agency.

A new international study shows that adults with ADHD who recognize and use their personal strengths report higher well-being and fewer mental health issues. Researchers from the University of Bath, King's College London, and Radboud University Medical Center examined strengths like creativity and hyperfocus in 400 participants. The findings, published in Psychological Medicine, support strengths-based approaches in ADHD care.
