Bilateral tactile agnosia: a case report.
This study reports a 64-year-old right-handed male who manifested bilateral tactile recognition deficits. They were diagnosed as bilateral tactile agnosia, since the patient showed difficulty in semantic association of objects despite preserved hylognosis and morphognosis. The patient had a bilateral lesion in the subcortical region of the angular gyrus. The case reported by Endo et al. (1992) ...
متن کاملPure Amorphagnosia without Tactile Object Agnosia
A 54-year-old female showed amorphagnosia without ahylognosia and tactile agnosia 40 days after the onset of right cerebral infarction. Her basic somatosensory functions were normal. The appreciation of substance qualities (hylognosia) was preserved, but the patient's inability to recognize the size and shape (morphagnosia) was confined to 2- and 3-dimensional shapes (amorphagnosia) in the left...
متن کاملLeft hand tactile agnosia after posterior callosal lesion.
We report a patient with a hemorrhagic lesion encroaching upon the posterior third of the corpus callosum but sparing the splenium. She showed marked difficulties in recognizing objects and shapes perceived through her left hand, while she could appreciate elementary sensorial features of items tactually presented to the same hand flawlessly. This picture, corresponding to classical description...
متن کاملThe nature of tactile agnosia: a case study.
A chronic tactile agnosic with a small, MRI-documented left inferior parietal infarction underwent detailed somesthetic testing to assess (1) the acquisition of sensory data, (2) the manipulation of somatosensory percept and its association with previous knowledge, and (3) recognition occurring at a deeper taxonomic level. Results suggest that tactile agnosia can arise from faulty high-level pe...
متن کاملTactile agnosia. Underlying impairment and implications for normal tactile object recognition.
In a series of experimental investigations of a subject with a unilateral impairment of tactile object recognition without impaired tactile sensation, several issues were addressed. First, is tactile agnosia secondary to a general impairment of spatial cognition? On tests of spatial ability, including those directed at the same spatial integration process assumed to be taxed by tactile object r...
