Cortical Paralysis of Touch [Die Kortikak Tastlähmung], (Mortals, f. Psychiatr., February, 1906.) Kramer

Published online by Cambridge University Press:  19 February 2018

Extract

It is doubtful if there be a special sense enabling us to recognise the form and consistency of objects independent of other sensations such as pain, pressure, weight, heat, electricity. Nevertheless, cases in which there was greater impairment of the feeling of touch than of the other modes of common sensation have been described under the title of “astereognosis.” To the consiceration of this subject, Dr. Franz Kramer has contributed a paper of thirty pages. He describes ten cases very carefully tested by himself. These are too long to reproduce, but we gather the following considerations from his observations and citations from other writers on the subject. It seems probable, that the loss of sensibility to touch is but a degree in the impairment of common sensation. Where to fix this degree is difficult owing to the complicated feelings and motions used to ascertain the outward form of objects. There are cases described in which the loss of tactile sensibility was much greater in proportion than the derangements of other qualities of common sensation. Perhaps similar inequalities of relation exist in normal persons.
