We studied 171 consecutive patients with an acute hemispheric stroke (69 right hemisphere, 102 left), at 2-3 days post-stroke. A standardized test battery, previously validated in patients with acute stroke, was used to detect a wide variety of neglect phenomena and related disorders. Visual neglect was found in 82% of assessable right hemisphere patients and 65% of left hemisphere patients. Hemi-inattention was found in 70% of right and 49% of left hemisphere strokes. Tactile extinction was found in 65% of right and 35% of left hemisphere patients; allaesthesia in 57% (right), and 11% (left); visual extinction in 23% (right) 2% (left). Anosognosia was found in 28% (right), and 5% (left); anosodiaphoria in 27% (right), and 2% (left); non-belonging in 36% (right) and 29% (left). Visual neglect occurred more commonly in left hemisphere stroke than previously reported. Although neglect phenomena and related disorders were associated with right hemisphere damage, it is possible that language difficulties obscured their presence in some patients with a left hemisphere stroke.
