A new form of clinical treatment is proposed for dystonias and torticollis using flunitrazepan (FN), a powerful agonist of all benzodiazepine receptors of GABA neurons. FN has a specific effect in dystonic patients, specially those in which the hypnotic effect of this drug is absent or diminished, thus suggesting the existence of two different neurochemical categories of dystonias.
