TL;DR: At a leading London children’s hospital, 77 children with PRES, a sudden brain-swelling syndrome, were reviewed over 20 years. Nearly 4 in 5 first showed up with seizures, almost all had another serious illness, and about a third of those given seizure…

TL;DR: In a German study of 34 people recovering from LGI1 encephalitis, a rare autoimmune brain disease, brain scans showed changes well beyond the memory centers usually blamed. People with more of these changes had poorer thinking scores and recovered less.…

TL;DR: People with a common type of heart failure scored lower on thinking tests than healthy people of similar age, and an MRI sign of the brain’s fluid-clearing system was lower on the left side of their brains. Lower values of that sign went with lower thin…

TL;DR: In 86 people from one hospital in China, those with Parkinson’s and mild thinking problems showed changes in how water moves through parts of the hippocampus, a memory center. The hippocampus was not measurably smaller, suggesting a diffusion scan may p…

TL;DR: A 2026 systematic review and meta-analysis in Journal of Alzheimer’s Disease found that choroid plexus volume, an MRI-visible structure involved in cerebrospinal-fluid regulation and immune signaling, was larger in Alzheimer’s disease than in healthy co…
