Total anterior circulation stroke syndrome (TACS) refers to the symptoms of a patient who clinically appears to have had a total anterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.

It is diagnosed when it causes all 3 of the following symptoms:

  • Higher dysfunction
    • Dysphasia
    • Visuospatial disturbances
    • Decreased level of consciousness
  • Homonymous hemianopia
  • Motor and Sensory Defects (≥2/3 of face, arm, leg)
