Do Hyperhidrosis Patients Have Poor Tactile Acuity?
That is the $ 64,000 question.
What is tactile acuity? It is defined as “the keenness or sharpness of the sense of touch, usually measured by the two-point threshold. Also called touch acuity.
Investigators at the Unit of Movement Disorders and Neuromagnetism, Section of Neurology, Fundacion Santa Fe, Bogota, Colombia; Uni.ciencias Research Group, Universidad Nacional, Bogota, Colombia looked at this phenomenon of tactile acuity in patients with hyperhidrosis and published the article in Neuroscience Letters in August 2008 (volume 29, pages 332-334).
To test this hypothesis, they investigated tactile acuity and cortical plastic changes in patients with primary hyperhidrosis and their relatives who do not have hyperhidrosis. They found that “sensory processing is abnormal in primary hyperhidrosis, with a lack of plastic cortical somatosensory changes regardless of clinical condition. These modulatory abnormalities would affect gating processes in the somatosensory cortex of the brain.”
These findings are interesting and their clinical significance should be elucidated in the future.
