Significant hyperhidrosis on the paretic side of the body was verified in 55%of the patients at baseline,in 74%after 5 minutes of heating,and in 77% after 10 minutes of heating.Hyperhidrosis was established throughout the body and correlated with the severity of paresis,the presence of reduced muscle tone,and extensor plantar response.The phenomenon of hyperhidrosis in hemiparetic patients reflecting autonomic dysfunction seems to be a common manifestation that should be listed among the expected consequences of brain infarction.This sweating disturbance might be attributed to a lesion of a putative sympathoinhibitory pathway controlling sweat.The failure of this pathway could also be related to other manifestations of sympathetic hyperfunction,e.g.,cardiac complications.Therefore,assessment of sweating may provide a new,important aspect in the evolution of stroke patients. |
