Stereognosis

Stereognosis

Stereognosis is the ability to perceive the form of an object by using the sense of touch. This sense, along with tactile spatial acuity, vibration perception, texture discrimination and proprioception, are mediated by the Dorsal Column-Medial Lemniscal system of the Central Nervous System. People suffering from Alzheimer's Disease show a reduction in stereognosis [F. J. Huff, J. T. Becker, S. H. Belle, R. D. Nebes, A. L. Holland, and F. Boller. (1987). Cognitive deficits and clinical diagnosis of Alzheimer's disease. Neurology, 37:1119] . For other types of dementia, stereognosis does not appear to decline. According to the GP Notebook at http://www.gpnotebook.co.uk, stereognosis is a higher cerebral associative cortical function.
