A Total Anterior Circulation Infarct (TACI) is a type of cerebral infarction affecting the entire anterior circulation supplying one side of the brain.
Total Anterior Circulation Stroke Syndrome (TACS) refers to the symptoms of a patient who clinically appears to have suffered from 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)
For more information, see stroke.

Famous quotes containing the words total, anterior and/or circulation:
“The word infant derives from Latin words meaning “not yet speaking.” It emphasizes what the child cannot do and reflects the baby’s total dependence on adults. The word toddler, however, demonstrates our change in perspective, for it focuses on the child’s increased mobility and burgeoning independence.”
—Lawrence Kutner (20th century)
“I find it more credible, since it is anterior information, that one man should know heaven, as the Chinese say, than that so many men should know the world.”
—Ralph Waldo Emerson (1803–1882)
“The circulation of confidence is better than the circulation of money.”
—James Madison (1751–1836)
