The “gunslinger” sign in progressive supranuclear palsy – Richardson variant

Dystonia is a clinical feature that may co-occur with Parkinson's disease as well as atypical parkinsonian disorders, including but not limited to progressive supranuclear palsy and corticobasal degeneration [1]. Over the past years, dystonia in atypical parkinsonian disorders has been thoroughly investigated, with particular interest in the disease-related differences in frequency, severity, body parts involved, relationship with the onset of parkinsonian features, and dopaminergic treatment [1,2].
