Alzheimer's Disease vs Control: albumin ratio (CSF/Serum and/or Plasma)
Meta-analysis Results: The ratio of albumin protein in the cerebrospinal fluid compared to levels in the plasma or serum was slightly higher in people with Alzheimer’s disease than in controls (effect size = 1.103, p = 0.02564). The effect was marginal. The albumin ratio is considered a measure of blood-brain barrier function.
