This cross-sectional study of 100 acute ischemic stroke patients examined whether signal intensity in normal-appearing white matter on FLAIR MRI correlates with leukoaraiosis burden. Results showed that white matter signal intensity increased near leukoaraiosis borders and was independently associated with leukoaraiosis volume, suggesting structural abnormalities extend into apparently normal brain tissue.
This retrospective study of 970 stroke/TIA patients found that elevated sST2 levels independently predicted atrial fibrillation detection after stroke (AFDAS), with sST2 showing superior predictive value (AUC 0.815) compared to conventional risk factors. Adding sST2 to a conventional risk model significantly improved prediction accuracy for AFDAS in acute stroke patients.
This review examines the relationship between loneliness and social isolation as major risk factors for Alzheimer's disease and cognitive decline, with particular attention to sex differences. The authors discuss mechanisms linking isolation to AD pathology and propose approaches for developing prevention and treatment strategies based on understanding these associations.
Researchers developed a tablet-based software application designed to slow cognitive and communicative decline in individuals with Alzheimer's disease for home use. A randomized controlled trial with 32 participants (mild, moderate, and severe stages) compared outcomes between those using the application plus pharmacological treatment versus pharmacological treatment alone.
This health economics study examines costs associated with using neuroimaging (PET and MRI) to identify Alzheimer's disease patients most likely to benefit from lecanemab treatment over three years. The authors highlight a critical concern: approximately 78% of patients with mild cognitive impairment do not progress to dementia, making prophylactic treatment in all MCI patients costly and ethically problematic; they identify combined fluorodeoxyglucose and MRI imaging as the most cost-efficient approach at $177,000 per positive outcome with adjusted lecanemab pricing.
