ASCOD Phenotyping for Stroke

ASCO Criteria:

  • A: atherosclerosis
  • S: small-vessel disease
  • C: cardiac pathology
  • O: other causes

Assigns a degree of likelihood of causal relationship to every potential disease commonly encountered in ischemic stroke describing all underlying diseases in every patient

  • 1 for potentially causal
  • 2 for causality is uncertain
  • 3 for unlikely causal but the disease is present
  • 0 for absence of disease
  • 9 for insufficient workup to rule out the disease
