Document Summary
Adequate language difficulties with communication (use of language) Perceptual impairments: neglect, visuospatial processing, facial recognition (prosopagnosia, constructional, anosognosia, orientation, color recognition, executive function. Reduced sensitivity to stimuli or awareness of space. Can occur for r or l side lesions. Low incidence for left side lesions; much higher for right lesions. Inability to process visual information on left side of body. Stimuli on r-side captures and holds attention. Inability to shift attention from r to l. Reduced tactile perception (although body senses the stimuli) Describing only the right side of a scene from memory (driving down a street) Reading only r side of each page (confabulatory completions of left text) Writing- omission of letter strokes, spelling errors, perseveration of strokes and words, left-margin drift (deviation from left margin) Using only right side of objects (desk drawers) Eat food on right side of plate. Reluctance to scan and explore left hemispace. Right side bias (always starts on right side)
