Abstract:
QSART (quantitative sudomotor axon reflex testing) was performed in a patient with idiopathic pure sudomotor failure. Generalized reduction in thermoregulatory sweating and complete absence of axon reflex sweating were observed, suggesting a deficit of sweat gland cholinergic synaptic transmission or receptors. QSART responded promptly to treatment. Putative pathophysiological mechanisms are discussed.
