[Clinical and CT aspects of muscular dystonias].

Abstract

Clinical, EMG, genetic and CT investigations were performed on 16 subjects suffering from Torsion Dystonia. We obtained the following results: i) genetically most cases were sporadic, only two could be considered autosomic dominant; ii) one of the pedigrees, with many patients, confirmed that spasmodic torticollis is not a distinct form from that of Dystonia Muscolorum Deformans; the two forms must be included in one disease called "Torsion Dystonia", as maintained by some Authors; iii) we found that the various drugs employed, rarely produced improvement, although benzodiaze4pines have given some benefit; iv) CT findings were not specific, though useful for differential diagnosis.
