emotional hyperhidrosis, an autosomal-dominant disorder of the eccrine sweat glands, most often of the palms, soles, and axillae, in which emotional stimuli (e.g., anxiety) and sometimes mental or sensory stimuli elicit volar or axillary sweating (usually not both in the same individual). Eccrine sweat glands in other areas of the body are affected less often and are less sensitive to such stimuli.
