  • Sarcopenia is when people lose muscle mass and strength as they get older, and there's no clear agreement on what it exactly means worldwide.
  • A group called the Global Leadership Initiative in Sarcopenia (GLIS) worked to define sarcopenia better by getting experts from around the world to share their opinions.
  • They found that most experts agreed that things like muscle mass and strength are really important to understanding sarcopenia and that it becomes more common as people age.

Article Synopsis
  • Brain perfusion and blood-brain barrier integrity are compromised early in Alzheimer's disease, leading to increased vascular issues.
  • Single nucleus RNA sequencing revealed that endothelial cells in Alzheimer's patients show gene expressions linked to AD susceptibility, particularly involving β-amyloid and impairments in vascular signaling.
  • The study suggests that targeting vascular inflammation and enhancing angiogenesis may help reduce vascular dysfunction and potentially slow down the onset or progression of Alzheimer's disease.
