The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Placental health in late pregnancy linked to childhood ADHD

Attention deficit/hyperactivity disorder (ADHD) in children may be associated with problems with the health of the placenta during late pregnancy, according to a new study by University of Iowa Health Care researchers.

Swedish study links lower midlife cognitive scores to future strokes

Adults in their 60s who scored lower on tests of overall thinking ability, memory and how quickly they processed information were more likely to have a stroke years later, according to new research conducted in Sweden, published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

Fractionated radiation reduces brain cancer recurrence and boosts survival

Mayo Clinic researchers led a multicenter study that found dividing radiation into several treatments, known as fractionated stereotactic radiosurgery, reduced the risk of cancer returning after surgery for brain metastases and was associated with improved survival compared with delivering radiation in a single treatment.

What older adults do on screens may matter more than total screen time

Across 8,996 older adults in four cohorts, television viewing was associated with poorer global cognition, while computer use was associated with better cognitive performance, with the strongest positive associations at low-to-moderate levels of use. Mendelian randomization supported these opposing patterns and linked genetically predicted television viewing time to lower left insula volume, which accounted for an estimated 14.8% of its association with poorer cognitive performance.

Radioactive collagen tiles double survival for brain metastasis patients

A multicenter clinical trial led by researchers at The University of Texas MD Anderson Cancer Center has found that implanting collagen tiles during brain surgery to deliver targeted radiation therapy dramatically improved tumor control, lowered the risk of recurrence and improved overall survival compared to current standard of care for patients with newly diagnosed brain metastases in need of surgical resection.
