[Familial neuralgic amyotrophy].

The authors provide the reported data concerned with differential diagnosis of hereditary and sporadic neuralgic amyotrophy. Describe own observations where members of the same family (mother and son) suffered from neuralgic amyotrophy. Attention is concentrated on the fact that in both cases, the disease started at the preschool age and was of recurrent nature. In the mother, an attack of neuralgic amyotrophy occurred in the postnatal period, in the son, successive exacerbation of the disease occurred in the form of 4 consecutive attacks of neuralgic amyotrophy which provoked deep paresis of the muscles of the shoulder girdle and both hands. After 1.5 years the muscles indicated practically regained their power.
