Dystonia--a potential psychiatric pitfall.
D G Owens


The manifold presentations of dystonia have been acknowledged as a spectrum of illness. Dystonia is primarily idiopathic or drug-induced; purely psychogenic causes would seem to be rare, although such an aetiology is commonly assumed. Response to medication in idiopathic cases is unpredictable, although anticholinergic medication and behavioural programmes are being evaluated.
