Urban residents with more greenery within 100 metres of their homes have a lower risk of developing dementia over time. This is the finding of a new study from Stockholm University and Karolinska Institute, which followed nearly 3,000 older adults for 16 years. Published in the journal Alzheimer’s & Dementia, the study highlights the importance of greenspace in the immediate surroundings of the home for sustainable urban planning that supports brain health.

A new study finds that mental health after trauma follows different paths—and tracking changes over time can help identify who may need lasting support. Following 1,035 Israeli adults for six months after October 7, researchers found that most maintained relatively low distress or recovered over time, while others experienced persistent or worsening symptoms. These patterns helped predict later post-traumatic stress symptoms beyond distress levels at a single assessment. Early positive emotions and viewing the world as safe were associated with better outcomes, while empathy, reflecting emotional resonance with others' suffering, was linked to greater distress. The findings highlight that severe early distress does not necessarily signal lasting difficulties—and that repeated assessments can help distinguish recovery from an ongoing need for care.

Better electronic health (e-health) literacy actively drives young adult patients into doctors' offices rather than replacing professional consultations with self-treatment. This is the conclusion of a new study published in the De Gruyter Brill’s journal Open Medicine, titled “e-health literacy, health-seeking behaviors, and perceived ease of use of digital health systems in outpatients.”
