Riassunto

Il termine distonia definisce un movimento involontario patologico, conseguenza di un’alterazione del tono muscolare, caratterizzato dalla presenza di movimenti e posture anomale [1]. La distonia deve essere differenziata da altri movimenti patologici come il mioclono e la corea ed è il risultato di una disfunzione del sistema extrapiramidale, in particolare del circuito cortico-sottocortico-talamo-corticale [2]. La distonia può essere classificata, in base all’età di esordio, in infantile (0–12 anni), adolescenziale (13–20 anni) e adulta oppure, in base al coinvolgimento dei segmenti corporei, in focale, segmentaria, generalizzata ed emidistonia. La classificazione eziologica include la distonia primaria (DP), le sindromi distoniche plus, le distonie associate a malattie eredodegenerative e le distonie secondarie a condizioni patologiche acquisite.
