Characteristics of strokes in subjects with hemi-neglect. Columns as labeled. ’The right column summarizes the results by the thermal pain submodality as indicated by the words Hot or Cold, as labeled.’ The type of abnormality of thermal extinction attention is indicated as follows: Extinction ratio (ext) for thermal stimulation on the left over both sides versus the right over both sides, Mislocalization (ML) proportion of mislocalized thermal stimulation with stimulus presentation on the left versus the right side or Misidentification (MI) proporteion of mislocalized stimulation on the left versus the right side. All strokes were on the right hand side and all symptoms were on the left. See Methods: tests of extinction. Abbreviation: AF – atrial fibrillation,, DM – diabetes mellitus, FAL – face arm leg, HBP – high blood pressure, hyperchol – hypercholesterolemia, MCA – middle cerebral artery.
