American football head impacts tied to increased brain damage and cognitive decline

Repetitive head impacts in former American football players are linked to increased perivascular space volume, which correlates with cognitive decline and neurodegeneration. The study suggests that the force of head impacts may be more critical than frequency, with potential protective effects from β-blocker use.

New ESC guidelines highlight broader approach to managing chronic coronary syndromes

The 2024 ESC Guidelines on the management of chronic coronary syndromes (CCS) include a focus on both larger and smaller blood vessels of the heart; new models to estimate chances of blocked large arteries (so-called obstructive coronary artery disease); optimal selection and sequence of tests; drugs and interventions to prevent disease complications and improve symptoms, and the fundamental role of patient involvement.

PET imaging and proteomics reveal distinct protein signatures in Alzheimer's disease progression

Researchers used PET imaging and proteomic analysis of cerebrospinal fluid to study amyloid β and tau tangle loads in Alzheimer's patients, identifying 127 proteins linked to disease progression. The findings highlight distinct molecular pathways and potential therapeutic targets.
