Acquired idiopathic sensory neuropathy. Report of three cases with a prolonged follow-up.

We have followed for more than ten years three women suffering from a S.N. which appeared in their fourth decade. In these patients no malignancy or other known toxic and infectious aetiologies could be found. According to the authors the clinical symptomatology as far as the C.S.F. and the neurophysiological findings justify the separation of S.N. from G.B.S., being the first disorder characterized by an elective damage of the neurones of the ganglia of the posterior roots. Therefore the eponym of "ganglio-neuronopathy" seems appropriate.
